Need Another GT Hit

After reviewing the Carisma GT24R, a miniature Pikes Peak replica and thoroughly enjoying racing it around the House, Garden, outside on Tarmac (hell, anywhere I could find an imaginary Rally Course to test it on!). I next wanted to stay with small form factor RC, but with a vehicle that had more Off Road capabilities (Putting it bluntly: I wanted to get some jumps in!). A few phone calls later and along came a small box, it contained both of the GT24R’s freshly born siblings …

The GT24T (Monster Truck) and the GT24TR (Truggy)

Big Similarities – Subtle Differences

Who doesn’t love a cool Monster Truck or Truggy?

Both of these share the same chassis as the GT24R with its fantastic micro brushless power system and well designed and manufactured suspension and steering, however there are a few differences.Apart from the obvious body shell change, the wheels are different too. Larger wheels with deeper and wider tyres, allowing for more grip on the loose stuff, body posts are present but not used and the rear bumper from the GT24R is not installed or needed

Chassis Rear
Underneath the bodyshells the Monocoque Chassis and running gear is the same
Chassis top
The hologram sticker ensures the authenticity of this Cariama product

Unlike many other small scale RC manufacturers who like to offer smaller form factor Transmitters with their products, Carisma have coupled the GT24 series of cars with the very much full sixed CTX8000 transmitter.

Controller
The cars may be small, but the Tx is full sized (and featured!)

It’s both ergonomic (fits the hand nicely), and full featured. It also offers trims for steering and throttle, servo reversing along with an adjustable steering rate thumb wheel conveniently placed on the handle by your thumb (you will see later why this is a good idea).

Good for Kids N Newbies Too

The CTX98000 also comes with a rubber throttle limiter that you can slide over the trigger, so it stops the driver using full throttle. Something that would be useful when you hand the remote to a new to RC driver or young child for example.

Chassis top close
Note the Velcro on the side…no body posts required!

Chassis under close

The chassis is a vented enclosed monocoque design and is super sleek, hiding inside under more than adequate protection all of the electrics  like the fast steering servo, and the 8000kv brushless motor. Keeping little fingers (or big ones) away from any hot or moving parts. (no scorching fingers on hot motors here) alongside keeping all the muck outside where it belongs.

Chassis battery empty
The space under the chassis offers space for either a 1 or 2S LiPo

Sliding open a small hatch on the bottom reveals a very neat battery compartment, which the 1s brushless battery fits in with ease. This is where I made my first upgrade, as I had already tried the GT24R (insert link) on a 1s battery and loved it, but the animal in me wanted more. I thought why not give in and go with a 2s I had ready to slot in, cue big demonic grin!

Chassis Battery Full
Tetris skills required…its tight but possible!

The official Carisma upgrade 2s battery is a tighter fit than the stock 1S offering, but once I engaged my Tetris brain, I found an easy way to fit it. keep the red JST connector against the inside of the chassis, then feed the battery in, the balance lead will fit perfectly at the end of the battery…someone designed this to fit well.

No Slop & Well Designed

Suspension again is remarkably sturdy for its size and I’m still shocked at how little play there is in the joints, especially when you consider how much slop is in some 1:10 scale or larger cars. The advantage to this is that the handling won’t be compromised by lots of play, as even a small movement in this scale could change camber/caster or toe by a large percentage. In short:-

No Slack = Predictable Driving = More Fun

The wheels are kept on the ground with twin wishbone suspension , which does not have adjustable geometry, but does allow 2 different shock mount points both top and bottom, alongside 2 steering arm positions on the hub, neither of which have any bump steer when I tested them.

Chassis under
This could be a 1/10th or even a 1/8th…but its way smaller than that!

For those that don’t know, bump steer is when the steering arms are not designed with the same pivot point geometry as the suspension, so as the wheel is moved up and down it causes the wheel to turn in or out. this makes the handling not so good and is best avoided. Thankfully Carisma have got this right and you don’t need to worry…

DSC05842 copy
The design is tough and robust…designed to be run not looked at!

Shocks are friction shocks with fixes spring rates, although I believe that oil filled dampers are available as an upgrade if its something you wanted to do, along with carbon shock towers and all other manner of goodies.

DSC05841
The stickers on each wheel add additional detail…while mainitaining the strength of a dish

I did my old skool drop / bounce test and if you are racing this competitively, then I would look at the shock upgrade, if you are having fun with it, ragging it about with friends, I would not worry the stock shocks work well.

All of the models are 4WD and pack a differential front and rear, meaning no scrubbing when turning and more grip. There is a built in slipper clutch too, there is a chance I might need it with 2s power!

2s battery
1S is fast, but 2S is ballistic!
charger
USB LiPo charging offers safety for younger users, but remember in some terratories the vehicles dont ship with LiPo or Chargers

Body wise unlike the GT24R, no body mount or pins are needed, instead you have a foam extension on the side of the chassis and Velcro to mount the body. You don’t need to remove the body to change the battery, or to turn the car on and off, all of that is done on the bottom of that lovely enclosed chassis.

As mentioned earlier, there are two body styles, the Truck (GT24T) and the Truggy (GT24TR), it comes to personal choice which you prefer, both offer great visibility and do not affect the handling, means when racing your mates its easier to see which is yours

Ensure Body Sits Correctly

On the GT24T, the first time I drove it I had to move the body slightly backwards to stop the front wheels catching the body on full lock, but that took me a few seconds and was zero hassle to do, this was probably my fault from when I took the shell off for the photographs. It’s likely i did not put it back in the correct location based on the wheel wells, and I had just lined the Velcro up.

DSC05780
Probably the cutest Monster truck in the history of RC

Performance on 2s is blistering and you would have to be a driving god (well better than me) to drive in a standard house sized room at full throttle, I recon it could do a 24th wall of death quite easily !

DSC05847
I wonder how many back flips I can do with it? Only one way to find out!

Outside or in a larger space where you can give the Carisma GT24 its legs, OMG how can something that small manage such acceleration, the top speed is impressive and I would love to know what it works out on scale speed, I’ve now nicknamed the GT24TR “Bluebird”!

Watch Out For Grip Roll

Thankfully the CTX8000 controller comes with a handy steering travel/rate adjust so when you are bombing along at warp factor 5, you can dial down the steering so it’s not too aggressive and induces a high speed roll…. ok, I admit, I found this out the hard way. After belting along at full speed with a massive grin on my face, I turning sharply and let’s just say I stopped counting at 8 flips and started the walk of shame while it was still going.

DSC05766
Much more of a serious Race Stance…The Truggy looks epic!

Testament to Carisma, no damage, apart from a few scratches to the shell, which has to be expected when playing on concrete.

DSC05855
Note how much difference the wheels make to the overall look…

The suspension does a good job of soaking up the terrain, I did find the odd bounce now and again when going over some rougher parts at high speed, but that added to the fun.

We gave it a whole 1 minute before starting doing jumps, yes our resolve was that strong! (now you understand why we take the pictures before driving). These two are a hoot, and the more you have, the better it gets, having 2 or 3 racing round is fantastic fun for not a big outlay.

Verdict: Highly Recommended…can’t wait to see what they do next, a baby Short Course or Rock Racer would be cool. Or even a baby Crawler/Scaler…watch this space!

"No Mr Bradbury…I Expect You To Drive!"

Behind The Scenes @ The Gadget Show

Words & Images: Peter Gray

Earlier this year I was involved with another RC related challenge on the Channel 5 TV Program; The Gadget Show. We had been bouncing RC Car ideas back and forth for a while, but then in a single phone conversation and a follow up e-mail, the shows researcher explained what the challenge they had decided upon would entail…In short: RC Cars v A Bond Stunt Driver, my smile grew exponentially!

Jason Bradbury, a man who’s no stranger to RC in any form, or pushing the technology right to it’s very limits (something he’s done on more occasions than I can list here!). His credentials as both a very ‘hands-on’ Tech Reviewer and well known TV Tech Presenter are written in the annuals of Tech history. He even chose a Tamiya RC car as one of his favourite bits of tech in a recent top 100 gadgets TV countdown…so his love of the genre goes way back to those late 70s and 80s releases. We also must not forget that Jason has also achieved two Guinness World Records using RC tech. One for distance jumped by an RC car (using a HPI Vorza 1/8th E-Buggy), and another (I actually helped facilitate) a huge RC Loop-the-loop using a brushless 1/5th scale motorbike! So he can drive, knows the kinda crazy stuff we like to provide the program, and he has no fear…no fear at all!

Jason would be driving three different RC cars, each with a very unique attribute or speciality. His challenge would be to go up against professional Stunt & Rally Driver Mark Higgins, doing what he does best, driving a V12 Vantage S Aston Martin very hard, fast and very sideways. Marks CV is impressive. He’s worked on Bond films like Spectre, has (and currently ‘is’) driving cars in the Fast & The Furious franchise, and is about to attempt to set a new Isle Of Man TT course record for a car in a specially ProDrive prepared, Subaru WRX Sti. He’s also three-time British Rally champion and as such set the current record for a lap of the 37.75-mile course in 2014, with a time of 19 minutes and 15 seconds, and with a staggering average speed of 117.510 mph…so he can drive too, oh my can he drive!

The 3 tests chosen for each vehicle would be:-

· A Drag Race Challenge, side by side, point to point between the chosen RC Car & the Aston Martin. The main start line to the end of the main straight being the two points

· A Drift Challenge where the RC Car must mimic the 1:1 on a 1/10th version of track, using throttle finesse and maintaining a long, sweeping and controlled drift

· A Timed Auto Test Challenge where the RC Car will compete on the same circuit to test its agility, road holding and stunt driving capabilities against the clock.

To this end we enlisted the help of 3 very different brands, and 3 very different vehicles. Each was specifically chosen to offer an attribute that would aid it to compete in each challenge and thought through well in advance of this days filming.

Point To Point @100 mph+

12
Mr Wilcox Esq looking rather happy with the X-01

For the Drag Challenge I called in one of the latest generation of Traxxas X-01 (kindly supplied by Logic RC). This 1/7th scale RC Supercar is something I know well, as I reviewed one a couple of years back and had tons of fun with it. I also know a few people with them (Like RRCZ’s very own Mark Jordan). It’s a bit of a one trick pony, but what a trick! It’s capable of 0-100 in under 5 seconds and has a top speed of around 103mph. On those two performance figures alone, I knew we were in a with a shot at winning this. The latest incarnation has the TQi transmitter and Traxxas link app as standard, offering real time adjustment of basic setup parameters like trims and steering rate, right through to more complex drive effects and feedback from its telemetry sensors of Speed, RPM, Temperature, and Voltage. It also has something called a ‘Cush Drive’ built into the driveline that helps it absorb some of the immense forces encountered when you take a RC vehicle of its size and weight and take it from a standstill to over 100mph in just a few seconds. Developed specifically for the XO-1, the Cush Drive absorbs drivetrain shocks with a custom-shaped elastomer damper housed between the spur gear and the drive hub. Under extreme load (such as hard, high-traction acceleration), the elastomer flexes to dissipate shock without interrupting power flow. The result is instant acceleration with no wasted power. Its actually a very clever variation on a slipper clutch and (Hopefully) will ensure that the spur gears don’t get damaged at the point the vehicle is launched at speed. As well as the vehicle, Logic RC also supplied us Stuart Wilcox, technician extraordinaire, RC Racer and Traxxas brand ambassador here in the UK. Stuart would school Jason in the fine art of getting the X-01 between two points and fast and straight as possible (and avoiding any high speed mishaps along the way!)

Getting Sideways & J-Turn City…

16
The Yokomo of Matt Tunks

The second vehicle I called in for this challenge was a 1/10th Yokomo Drift Car (and the help of our resident Drift Guru; Matthew Tunks). Matthew is sponsored by the company and regularly competes and judges National and even International RC Drift comps. He brought over a selection of his latest 2 and 4WD drifters, but decided that the shaft driven DPR would be the most suitable for this challenge. It’s not the newest model in the range and has now been replaced by the YD-4. But would hopefully (with some tuition from Matthew), be an easier option for Jason to quickly ‘get’ and attempt to master in the short time they would have to get acquainted with each other.

22
The WR8 Ken Block replica…fast as (funk!)

Lastly for the times Auto Test Challenge I enlisted the help of a real Hoonigan. HPI’s Brushless WR8 Hoonigan to be exact with a replica Ken Block Ford Fiesta HFHV shell. Now this is another vehicle that we know back to front here at RRCZ. As a team we’ve reviewed both the Brushless and Nitro incarnations. Its based on the Bullet bloodline of vehicles, but has undergone a tweak here and there to lower arms and suspension. Instead of being a 1/10th Monster or Stadium Truck, its actually a 1/8th Global Rallycross car. Now if you haven’t heard of Ken Block, or seen any of his Gymkhana videos you must have been living as a hermit on a remote island somewhere…Here’s the latest (but its well worth watching them all historically right back from Gymkhana One!) :

Number 46 aside…the HPI car pretty much mimics the real thing, just without the excess tyre smoke. Its 4000kv motor on 3s LiPo power pushes out a very healthy 44,400 rpm and on stock gearing that’s around 60mph. But its not out and out acceleration we are after, the handling must be spot on, with an almost 50/50 weight balance and fast, responsive steering. Luckily HPI have all that in hand and have even added sway (anti-roll) bars front and rear and 11-spoke bright blue Speedline wheels shod with tyres that allow for grip and acceleration (especially on tarmac), but still allow the driver to feed in the power to break traction for performing do-nuts, power slides and even J-Turns.

25.jpg
You gotta love the Block livery…it makes you want to drive it like you stole it (or were given it to rag around without consequence!)

The car tends to offer the classic lift of oversteer characteristics of most 4WD’s, but still allows you to hit a tight turn fast and tap the brakes, unsettle the handling and then feed in the power again to ‘Hoonigan’ it round. This is definitely the right vehicle to attempt a Time Attack against a real car…add to this the fact that the person bringing the car from HPI was none other than long time RRCi and RCCZ collaborator Frank McKinney, it made our trio of vehicles and technical help truly complete.

Rocking Up @ Rockingham Motor Speedway

14
About to go and drift in the Aston together…and believe you me that’s a real experience

 

So on a very cold but sunny day in Spring we all met up at Rockingham Motor Speedway in Northamptonshire. The track was dry and the huge dedicated motor sports venue has everything from fast a banked oval circuit running around its perimeter to International Super Sportscar Circuit, National Circuit and even an infield Handling Circuit. On the banked circuit, the oval comprises four very distinct corners. The oval lap record is held by Tony Kanaan in a Champ Car, lapping in 24.719s, with a staggering average speed of 215.397mph! Obviously we wouldn’t be getting up yo anywhere near that, but the start line and first straight leading into turn one would be perfect for the drag race between the Aston martin and the X-01.

Away from the Oval, a section of the handling circuit on the infield was to be used for the 1:1 drift challenge. For the Yokomo RC Drift car, a perfect 1/10th version of the same challenge was also laid out by the Gadget production team and Matt. It was to be run on a totally smooth piece of outdoor concrete adjacent to the infield paddock and workshop areas. So smooth and shiny it was, that it looked almost tailor made for this challenge.

19
The perfect surface to learn to drift an RC car on…or so we thought!

Then the ‘Talent’ arrived on set. Jason Bradbury was his usual bouncy self, and raring to get stuck in with the cars selected, after 1st he was fuelled by fresh caffeine, and 2nd he had been instructed by each company about their particular vehicles idiosyncrasies and had a good play with each. Having worked with Jason for many years now, we just get on, both with each other and with the shoot in hand. Same age, same mentality and same outlook on life…we are serious when we need to be and have fun when we don’t (guess what aspect always wins!)

5
The production team of Chris and Ben mic up and Go Pro the car itself!

Mark Higgins appeared just as the first of two Vantage Aston Martin’s were delivered onto the set. He immediately fired it up and got himself acquainted with it on the main straight, and then on the infield. Considering it was a V12, but automatic (the manual V8 car would be delivered later in the day) he got it performing some very cool stunts. Huge tyre smoking power drifts around the apexes of the infield corners, a couple of very fast J-turns on the main straight and a serious of mock time trial manoeuvres around random stationary objects, other cars and traffic cones.

2
Mark Higgins shows us why he’s driven cars like this V12 Vantage in films like Spectre…Its the tyres I felt sorry for (NOT!)

A Drag Race…For Pink Slips (Not!)

So we set up for challenge number one, the Drag Race. Stuart Wilcox had the X-01 charged and ready to go, its two 3S, 5000 mAh LiPo cells offering the vehicle 22.2v of power and the Castle Creations 1650kv motor 36,630 rpm. When used in conjunction with the High Speed Gearing and high downforce splitter, its a potent combination!

6
Chris getting a smooth Dolly Shot of the X-01 for the cars on screen tech intro

For the first few runs the X-01 was left in its locked mode. This means that its top speed is initially limited to just 55mph via the Traxxas Link App. This would allow Jason to get a feel for the cars handling and how it accelerates from a standing start. After a few blasts up and down the main straight, Stuart used the app and his IPhone to Unlock the car and enable the Castle Creations Mamba Extreme ESC to give full power on demand, and that amazing 103mph top speed.

8
Jason’s first go with the X-01…Stuart offering advice about feeding in the power

As it was so cold, getting heat into the tyres was vital as the compound is quite hard at low ambient temps. A few mock burn outs later and they felt sticky and warm, but keeping them that way was proving difficult. Stuart did a few runs to check the car was trimmed correctly and even he had to back off the power at times when the car suddenly started to drift to the left or right, losing traction even at 70mph+. Then the transmitter was passed up to Jason who was perched on the gantry high above the start and finish line, offering him a full view of the track, but sideways on. Possibly not the easiest of positions for a drag race (I always prefer to stand behind the car, so I can see it it veers off in any way and correct it). He had a few test runs and initially had the same issues as Stuart. The tyres just wouldn’t stay warm enough in the close to freezing temperatures. Jason would punch the throttle, the car would speed off, accelerating to 60mph in about 3 seconds and then 100mph in under 6. If it veered off course, he immediately would back off halting that run. When it went wrong we had a few tense moments, but he kept it off the barriers and in one piece.

When it went right it was a sight to behold. The X-01 may be over three years old now as a design, but it’s a vehicle that simply hasn’t been toppled by any other in the RC industry. Traxxas set out to design and build the worlds fastest commercially available RC car and they did just that. Seeing it, in its latest white livery streaking down the track was amazing. Having reviewed one myself I know that ‘Buzz’ and hit of adrenalin you get when you first get a 100+ run, and it would be no different for Jason.

7
Stuart Wilcox in the pit lane making sure the car was trimmed and ready to go…Note the tyre marks from Mr Higgins!

Drivers Ready? Cars Ready? Go…

We had an official on hand from Rockingham to start the Drag Race standing between the two cars with a chequered flag, and as they lined up side by side for the first of 3 runs, the sheer size difference made it seem a very David and Goliath battle. Run one and two would be to practice, and then run three the actual challenge recorded for the TV show.

11
The gantry overlooking the start line and side on to the track offered Jason a full view of the entire straight

Run One: The flag dropped and Mark floored the accelerator of the Aston, even being a Automatic, he had the option of putting it into a sports mode, and as Q says in Spectre “It’ll do 0-62 in 3.2 seconds…”. He had also switched off traction control and launch aids, wanting to be in as much control over the delivery of power from the V12 to the tyres as possible. That was pretty evident by both the speed of the launch and the amount of tyre smoke he produced too! From the RC side Jason gave the X-01 a good squeeze of the throttle and both cars sped away from the start line like rockets. It was neck and neck until about half way up the straight and then Jason saw the Traxxas starting to drift towards the Aston and backed off. Having done previous RC challenges where the RC vehicle ended up being run over by the full sized one, he learnt from that and wanted it to survive the challenge.

10
Side-by-side…both drivers nervously awaiting their chance to pin the throttle

Run Two: This time it was Mark who actually backed off, correction, the Aston did! It seemed that on its full throttle launch from the start line, the Aston sounded like it miss-shifted about a third of the way up the run and went from a tyre spinning rocket ship, to a Sunday afternoon plodder…Jason and the X-01 sped away and passed the finish markers (Cones) at what looked like nearly maximum speed. I could see the grin from Jason right from my vantage point on the other side of the track!

“Best Of Three?”

9
It was time to see who had the fastest car…and nerves of steel

This was what Jason jokingly shouted to mark as the cars lined up again for the final run. This was it, the real deal. The flag dropped, the cars both launch perfectly and sped away into the distance. For the first 3rd of the run it was completely neck and neck. If you were a betting man (or Woman) it would be a hard thing to put odds on. But then spurred on by the fact the tyres were starting to consistently give grip, Jason pinned the throttle and the X-01 gradually moved ahead of the Aston, passing the finish line a good 1:1 car length ahead. We all shouted and screamed, RC had won its first victory over the real thing. Jason was jumping up and down on the gantry and Mark showed his feelings by spinning the Aston round and power sliding it back up the straight and performing a handbrake turn top finish back perfectly on the start line again. We then moved onto the Drift challenge…

But First Mark Took Me 2 laps Of The Circuit – ‘Sideways’…

4
What gets me is that he’s so calm while driving like this…lighting up the rubber at every opportunity

The infield circuit location wasn’t too far away but carrying a heavy camera case and lenses I had my hands full. Then Mark shouted over for me to jump in the Aston with him. I needed no encouragement. He then took me for two laps of the handling circuit, clutching my camera case between my feet and most of it completely sideways, smoke billowing out from the rear tyres. Now remember this is an Automatic and occasionally the electronics tried to cut back in and offer traction control and bring the Vantage S back onto the straight a narrow. It actually did it mid drift once, and you went from being pushed into the corner of the seat and pulling a few G, to it snapping back to normality and cleanly taking the apex pointed perfectly in the right direction. I know which I preferred and I would show you the video I shot on my phone but I may have uttered a few expletives in my excitement! Mark truly is a master of his art and to him driving like this, in full control is simply another day in the office.

Aston Challenge Two: Mark Takes Jason Drifting

15
Mark made the Drift Challenge look easy…as long as the traction control didn’t cut in mid-corner!

Cones were laid out between two parts of the track, and two apex’s were earmarked for Mark to drift the Aston around. With Jason in the passenger seat he did just that, executed three runs, all perfectly sideways, transitioning between both drifts and offering just enough throttle to control the drift, while still smoking those poor tyres…It was effortless, and with only one minor hiccup (again when the traction control cut in mid-corner). Marks runs were a master-class in car control and his abilities as a driver. The benchmark was set, and the benchmark was very high.

RC Car Challenge Two: Jason Takes The Yokomo Drifting

20
Its was harder that Jason anticipated, and really shows the skill required to ‘properly’ drift a RC car

With some expert guidance from Matt Tunks, Jason got started on the Drift Challenge. Just like the Aston, first initiating and then maintaining a drift is all about breaking traction, throttle control or Finesse, Counter Steering and knowing that point at which to balance all these factors. With Matt demonstrating it looked effortless and if this was a challenge between Mark and Matt it would be one that would be hard to separate the two. But it wasn’t. This was between mark and Jason, and what Jason soon found out was that real RC drifting is much harder than top drivers like Matt make it seem.

18
Jason tried time after time to get the right finesse on the throttle and lines…but to no avail

The initial learning curve can feel quite steep, and I have to admit, even after years of practice, it always takes me a few laps to get that ‘feel’ again and to be able to seamlessly thread a car through a series of apex’s in one fluid movement. Jason is a self confessed RC nut. He gives everything 110% and this was no exception, but try as he might he just couldn’t match Marks drift prowess. At the end of this Drift Challenge it was firmly: RC 1 – Aston 1.

With everything still to play for, it was a nice way to go into the final Challenge after a break for lunch: The RC v Aston Auto Test.

Come In Number 43, Your Time is Up…

23
No that’s not a Russian leader with Jason, that’s a very cold American…the one and only Frank M

After a healthy lunch in the track-side restaurant, and a coffee re-charge it was time for Mark to drive the manual Aston Martin Vantage V8 and Jason the HPI WR8 Ken Block replica. A large car park adjacent to the pit workshops had been allocated as the venue and a variety of challenges awaited both drivers. Cones were used to mark out a start line, multiple islands to drift around, sections to weave in and out of, then drive into and then reverse back out of, J-turn 180 degrees and then sprint for the finish line.

26
Note the Go-Pro’s attached to Marks Aston…I’m sure one fell off during filming and gave its life for the cause

What you must remember here is that the WR8 is (on the correct gearing) capable of a top speed of over 65mph with the 3S pack Frank McKinney had fitted. But this wasn’t about top speed. It was about acceleration, manoeuvrability and handling. Without waxing too lyrical its was also about man and vehicle in harmony, using each cars abilities to negotiate the course in as fast a time as possible. This was a very hard one to call as the course was designed to accommodate the Aston and yet the WR8 would have to cover exactly the same distance, and negotiate all the same 1:1 obstacles. Both drivers were allowed a couple of practice runs, they both watched each other safely from a vantage point on the roof of the buildings adjacent to the challenge.

28
OK, so admittedly its an older version of the Block livery, but it’s still Uber cool

It took both drivers a couple of attempts to get around the course cleanly, one J Turn that mark attempted didn’t swing the full 180 degrees and meant a time sapping correction before the sprint to the line. Jason took out one of the cones at speed and popped of a steering linkage and sheared off a body mount, but that was quickly repaired. Time wise you couldn’t call it between the two, and it would all come down to how composed they were during the challenge itself.

An Aston Attacks The Course

27
“Eyes right…” oh and wheels counter steering into the drift!

Mark went first and after being counted down by Jason, accelerated away from the line and made short work of the entire course. The Aston drifted perfectly, pirouetting around each Cone Island, it weaved perfectly around each chicane section, combining out and out tyre smoking power, with deft use of the handbrake and cars own weight and momentum. He then drove the car expertly into the cone parking bay that had been setup at the far end of the course, stopped fore just a Millisecond and then reversed the car at speed, wheels spinning and then performed a picture perfect J turn before sprinted to, and then over the line, stopping the Aston perfectly between both white lines and asking for his time from Jason. 36.30 seconds. That was fast, very fast…

‘Mr Bradbury’ Is Possessed By ‘Mr Block’

24
“Concentrate Jason, just not too hard…” words of encouragement from Mark or an attempt to unsettle Mr B?

Jason was very fired up for this and after warming up the tyres with a few impromptu donuts he then put the WR8 on the start line and waited for the signal to go. Mark was perched this time on the roof next to him, Jason’s view was again side-on to the whole area in question and with a “Three, Two, One!” from Mark, he was off!

30
The faces say it all…close was an understatement. The cars perfectly matched

The WR8 sped away as if possessed by Ken Block himself. It rocketed around both the cone islands (this thing corners like its on rails) and the tighter more technical parts of the course. Seeing a vehicle so small being driven at well over 50mph most of the time, even 60mph+ on the longer sections brought a smile just as big as Jason was showing to most of those faces (including mine) looking on. The last third of the course involved driving into that Cone Parking Bay and then after stopping, going full speed in reverse and J Turning the RC car before sprinting at over 60mph over the line.

Little n large…it’s all about perspective!

The pre-J-Turn would be Jason’s downfall. Even after performing two flawlessly in practice, as he pulled into the parking area, he got the angle wrong and hesitated. The WR8 needed to be corrected for its angle and then the J-Turn could happen. He then simply punched it and aimed for the line. Even with the pause and correction, Jason still managed a very fast transition, but that single aspect lost him valuable seconds and wasn’t the smooth, flowing all-in-one movement the Aston Martin had managed…The WR8 shot over the line and Jason stopped perfectly between the white lines. All eyes turned to Mark as he first showed Jason the time…then the cameraman. ”Nooooooo” came the shout from Jason, and Mark’s smile said it all…The Bond Stunt Driver had won!

Just 2 Seconds Slower!

29
It just wasn’t to be…2 seconds slower on the run and just half a second on a re-run…but man was it fun!

It was a very close fought thing. The RC car had passed the line in 38.43 seconds, and we were all convinced that without the pre-J-Turn mistake it would have been neck and neck. To prove this point, Mark let Jason try the course again. 36.50 seconds later he crossed the line. Close, but not close enough. Jason’s a good sport and said his first time must stand, and that’s the run that the program aired on TV. The day ended there. We all said our goodbyes, the crew packed up everything, Mark sped away in a very cool looking BMW M3, Jason disappeared in a Taxi to get his train back to London and Stuart Wilcox, Matt Tunks and Frank McKinney lines all the vehicles up for a final parting show for the mag before themselves packing away and departing Rockingham Raceway…it’s a wrap!

This is the smallest RC car I’ve had for many years, those memories are not particularly rosy, as often the smaller the car the more “toy” like it is, lets see how the Carisma GT24R fairs (and I hope it replaces some of those memories with shiny new happy on!)

Everythings in the box…bar the patience needed to wait for it to charge

Billed as a Ready To Run, with everything included is a great idea. One thing that always peeves me (and I’m sure I’m not the only one) is “batteries not included”, after spending a chunk of money, being asked to go and spend again is never a good feeling, even if its only a few quid for some batteries. This is certainly NOT the case with the Carisma RTR, everything is in the box to get you up and running. Thank you !

The hologram sticker says it all…genuine Carisma quality, performance & manufacture

What is the GT24R?

A Pikes Peak international hill climb inspired 1:24 scale car, for those that don’t know about Pikes Peak, it is probably the oldest hill climb event still running, it was first ran in 1916 in Colorado, USA. A 12.5 mile race with 156 corners, climbing over 4,700 feet from the start to the summit of the Pikes Peak mountain at just over 14,100 feet altitude.

21
The ‘Pikes Peak’ replica body is amazing…(very 6R4 Group B Retro too)

Ok, so that’s a serious hill, but why does that inspire a car design, and more importantly, one that we would want as an RC car. With all those corners and hairpins, often with no barriers, it takes a very well built car or bike to make it to the top quickly, and often some don’t make it at all.

The higher you go, the thinner the air, which reduces the power your engine makes. So to get up the mountain fast, sprinting from corner to corner requires MONSTER horsepower often over 1000bhp. coupled with massive down force produced from outrageously big wings to give lots of down force and grip. For a lot of petrol heads it is a holy grail event, so this little 1:24 scale RC car has a lot to live up to if its inspired by Pikes Peak.

What’s it like ?

Ok, so it’s all out of the box and laid out on the table, first impressions are very good, I’m immediately struck with the well printed group B rally car inspired body shell with its Pikes Peak wings and splitters sprouting out at jaunty angles, if it drives as well as it looks, this will be great.

Spares, tools, body clips, cells, LiPo and charger are all included!

Looking at all the included goodies, I can see a nut spinner, screwdriver, spare drive gears, different motor pinions, steering arms and even body pins alongside a lipo battery, charger and batteries for the transmitter, superb! the inclusion of the batteries is great, the drive gears and spare steering links are a total bonus.

15
Just think of the bodyshell possibilities for this platform…

Lifting the lid on the GT24R, I was very surprised to see a super neat completely enclosed chassis centre, a small door on the bottom houses the LiPo next to the power switch, and apart from cooling vents all the workings are enclosed/sealed in a lightweight but compact case. In this covered centre, there is a receiver, fast servo for steering and of course the power train, consisting of a LiPo ESC (Electronic Speed Controller) and an 8000kv brushless motor, driving through a slipper clutch.

11
Friction (not oil filled) dampers…but they work a treat on this light platform

The slipper clutch mates onto the front and rear differentials via a simple driveshaft arrangement. on 1s battery I’ve not had noticed the GT24R needing to use the slipper clutch, but its fantastic to have one installed by default. All of this terminates with the rubber tyres, which provide good grip on hard surfaces and carpet. Everything is supported throughout with full ball bearings and no friction bearings in sight.

14
Yes, it’s that small!, and no, my hands aren’t actually that big!

The only friction parts on this car are the suspension dampers, which are typically bouncy, but work acceptably at this weight, although oil dampers are available directly as an upgrade. Whilst I mention upgrades, there are also carbon shock towers, driveshaft upgrades and if you want to drive this more seriously, 2s LiPo and even a 12000kv motor, now we are talking Pikes Peak power!

Double-wishbone rear suspension soaks up all the bumps in style!

The suspension is double wishbone front and rear with adjustable shock mounts on both upper and lower points, so you can change the effectiveness of the shock absorber to suit your driving style.

THe included 2.4GHz CTX8000 has all the features you would ever need, some even for ‘racing’

As per usual one of the first things i do when I pick a car up is wiggle the wheels to see how much play there is in the suspension/steering. I take this (unless its been engineered to have play) as a mark of the build quality. the GT24R is all plastic and 1:24 scale, so i expected some slop, but I was flabbergasted, there is zero play in the steering and no binding, looking at the suspension, there is very little unwanted movement too. The engineering tolerances at 1:24 scale are tiny, yet they have been achieved and then some.

The included radio is the CTX8000 which alongside the usual trims for steering and throttle comes with a throttle limiter that you can slide over the trigger, so it stops the driver using full throttle. something that would be useful when you hand the remote to a new to RC younger driver for example, or for use indoors in a smaller space

5
The throttle limiter is simple, yet very effective. Perfect for the younger RC fans in the family!

As usual, with most models the steering rate is adjustable, however on the CTX8000, this is very conveniently located on a rotary thumbwheel on the handle of the controller.

7
Steering rate adjustment is just a thumbwheel away…

Very well placed so when your ‘hooning’ around like a loon at full throttle, you can easily dial back the steering throws to aid with high speed stability. Then put them back to full when you come to a hairpin with a quick slide of your thumb, after a few attempts it becomes very natural and effective.

6
Power, Trims, Bind & Servo Reversing, all easy to use and figure out in seconds

I’m very impressed with the engineering of this car and the attention to detail, both for those things in sight and hidden away, even down to having ‘handed’ body pins so its symmetrical. someone’s OCD at Carisma has been put to good use, and is noticed…

20
Now thats a silhouette of a very cool car…The GT24R Rocks!

Is it fast ?

Running on the standard 1s battery, running it outdoors on a hard surface, the acceleration is rapid and it has a respectable speed for its size. As mentioned earlier, I found myself turning the steering rate down for outdoor, as at higher speeds it is very easy to roll the GT24R with large steering movements, of course this is easy to do with the well placed thumb wheel on the CTX8000 controller

19
The view others should get if you race them! The 24R is the perfect fun bashing and race platform

Indoors, stick the throttle limiter on and I was doing good laps of the lounge, steering needed to be turned all the way up this time, and at times I wanted a little more for the last hairpin round the sofa (shhhhhh…please don’t tell the wife!)

Is it Pikes Peak fast? out of the box on a 1s battery, no, but switch to a 2s I would say so, or perhaps 1s with the 12000kv motor, and it would be very interesting, once the UK summer stops raining I can’t wait to try this and unleash some Pikes Peak power.

18
Part Pikes Peak, Part Group B Rally Car…we love the look, what do you think?

It’s nice to have options on the upgrade path, I’m not sure if the 12000kv motor will do 2s, if it will, that would be totally mental (I want one…)

The GT24R not really an off road car, although it handled loose dusty gravel surfaces well, especially when you consider gravel is like driving over a boulder covered road at this scale. Therefore I would say its better suited to a smoother surface to get the most out of the speed. There is more than enough speed to get airborne, and I found a nearby skate park a great playground do race round and have a lot of fun.

Before I Go…

One of the beauties of something this scale is the price, so its inclusive for you and a mate or 3 to get one each and have some fun races with them, something I would recommend, either that or in true Pikes Peak style, set out a course with lots of tight corners and sprint through it, timing runs and then passing the controller to the next driver. you can have a lot of fun for not a lot of money.

22
A true ‘Pocket Rocket’, especially on 2S and with a 1200kv motor fitted!

The advantage of the smaller 1s LiPo batteries is they take very little time to charge and they are not expensive, so you can either take masses of them out with you or just a couple and a charger.

23
WE just need 3 more now and we can have a RCCZ GTR office race!

In closing there are a lot of very nice touches on this car, and its fun to drive, I will try 2s when the weather gets better (classic British summer at the moment aka rain). The attention to detail and build quality is great and far beyond what I expected, some good memories have been created.

Thank you Carisma RC
