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!

Now, I’m no stranger to the RC4WD Trail Finder bloodline. And at last count I’ve built 3 rigs based on two generations of the kit and run a very capable RTR. With our recent SWB TF2 review by Daniel S getting all down and dirty at the RECON G6 UK Edition, I felt it wise to do something a little different with the latest review kit of the longer wheelbase we were sent by RC4WD.

For a start I decided to use the new Chevy Blazer body kit they had recently released. And while I was at it, the Billet V8 engine that replaces the stock motor mount and becomes part of a far more realistic looking driveline. I wanted a rig that while still performing Off Road, would also look cool as a fictitious daily driver, and be something that if I had the 1:1 vehicle as a donor, the time and the funds…would build myself for real!

A Classic US 4×4 gets the RC4WD and RCCZ treatment!

V8 Engine and Ladder Chassis

The start of any TF” kit build is always the chassis. You first bolt on the mounting points for the leaf springs and gradually build up what is essentially the backbone of the whole rig.

13
The basic chassis was built in just minutes and forms a solid backbone for the rest of the build

Remember to use Loctite Blue Threadlock or similar on anything that goes metal to metal, but metal bolting onto plastic should be just fine. The chassis braces, front chassis mounted servo mount  and shock hoops go on next, and then the plastic rock sliders and side on body mounting points.

14
The upper deck offers lots of space to evenly distribute your electronics

Next you fit the upper deck that provides a decent surface area for the ESC, main pack and receiver (or if you want to use it, you can also fit the kits rear splash proof receiver box that mimics a fuel cell). Personally I keep all my electronics on that plate to:- 1: keep all wiring runs as short and neat as possible and 2: So that if needed I can waterproof components myself. Most ESC’s are at least splash proof these days and for a scale rig that’s usually enough. As for receivers, its a simple enough task to use either an old school balloon, or more modern method of Plastidip liquid electrical insulation to waterproof the receiver and if running one, the BECs boards.

21
The Carisma ESC I used has programmable Drag Brake profiles and is LiPo compatible

My chosen Carisma brushed ESC with crawling mode was already deemed waterproof, as was the Spektrum receiver I decided to use.

V8 Power Plant…(Ok, 35t!)

Next I deviated from the traditional build schedule and took the Billet V8 Engine to bits to fit the 35t brushed motor I had chosen to use. Its a fiddly job but a little patience and lots of tiny bolts later and I was there. I made sure to check the internal gears in the bolt on transmission housing for grease. The R4 Ultimate Scale Single Speed Transmission has a gear ratio of 10.1:1 and perfectly compliments the V8 engine.

10
RC4WD have made Scale RC into a true artform

One thing to note is that the pinion and gears while being metal are 48DP so run very smoothly but aren’t as tough as the 32dp gears used on other rigs. You must make sure you mesh the pinion and primary gear inside the transmission perfectly, and that you threadlock the pinions grub screw…not doing so and the pinion moving is a big job top rectify…you were warned!

The alloy engine is the perfect way to disguise a 540 sized brushed or brushless motor

8
You can’t get much more scale than this…I stripped and re-greased its internals though

The R4 Ultimate Scale Transmission offers a gear ratio of: 10.1:1 and thus improving traction and torque at the axles

9
The 35t motor offers a great balance between Torque and RPM

We chose a 35 turn brushed motor for this build, the perfect balance between RPM and torque (even more so on 3s!). This ones re-buildable too

11
You could just put this in a display case a stare at it all day its that cool

V8 Scale Engine B_6

Once mated together the separate components work so well together and offer lots of scope to further accessorise and detail the engine inside the Blazers engine bay.

16
Sitting pretty and waiting to be detailed further

In situ the V8, Holly Rocker Covers and its pancake filter look right at home. Forward weight bias is greatly improved.

17
How can you not love this engine, transmission and transfer case…its so realistic

The engine was completed with an alloy pancake air filter and some Holly rocker covers. the whole assembly once bolted in place and linked directly to the 1.47/1 ratio Hammer Transfer Case added a real weight forward bias to the rig, perfect for climbing inclines and counteracting (with the use of weighted wheels) the heavier Blazer hard body and thus much higher centre of gravity.

Yota Time…

Next my attention turned to the included kit axles. The cast Yota Axles have a ratio of: 2.67:1 and are 176.5mm wide (measured at the hex’s). They, as ever come pre-built, but will benefit from setting aside a good hour to strip, grease and then re assemble using threadlock. You can just fit them but long term you will suffer the loss of bolts and premature gear wear, forcing the need to shim them. You simply bolt on the leaf springs and then they are affixed to the correct points on the chassis, anchoring them in place.

THe Ultimate Scale Shocks, Leaf Springs & Cast Yota Axles

Axles in place, the Ultimate Scale Shocks are fixed on next, and their sleek look (having internal springs) works perfectly in conjunction with the leaf springs and axles. As Daniel Siegl said in his recent TF2 SWB Jeep review, leaf sprung rigs drive so very differently to 4 linked, more traditionally suspension equipped ones. But they look so much more ‘Scale’ and ‘Realistic’!

19
The front steering servo mount on the chassis and Yota Cast Axle

Remember though that the  shocks are not oil filled and have internal springs. A small amount of oil seems to improve their action slightly, and unless over-filled they stay pretty leak free in use, but as ever experimentation is the key word. The leafs themselves have a period of time where they ‘Break In’ and become more supple in use. So we would suggest you let this process happen naturally and then fine tune the oil weight and possibly even the internal springs.

Fuelling Up The Look

FUEL

25
Bigger diameter wheels and tyres from stock raise up the rigs ground clearance

Now with the driveline, chassis and mostly stock running gear in place I decided that to give the Blazer body the look of a hybrid street/trail rig on steroids I would need to run bigger wheels and tyres. to this end I fitted a set of RC4WD Fuel Anza 1.7 Beadlock wheels and shod them in soft compound RC4WD Inteco Super Swamper “Siped” tyres, then during the build process adding 1.5 strips of stick on lead weight to each wheel and tyre combo.

Anza 1.7 Wheel Specs

  • CNC Machined Billet Alloy
  • Nut Cover with FUEL Logo
  • Scale Hex Bolts
  • OD: 43.8mm
  • Width: 24mm
  • Neg Offset: 7.5mm

  • X2 SS Compound (Super Soft & Super Sticky)
  • Inner Ribbing offers Sidewall Support
  • Outer Diameter: 114.2mm
  • Width: 40.7mm
26
Note the transfer case protective cover…

Once fitted they gave the chassis a slightly higher stance and ground clearance from the stock 1.55 Stamped Steel wheels and Mud Thrasher tyres included with the kit (Again these will be put to good used in a future project). Lastly I added the chassis mounted RC4WD Digital Steering Servo and once built the appropriate steering linkage.

Ignore that excess wiring coming out of the Spektrum Rx…It’s waterproof and designed like that!

From the front of the rig it offers a nice clean look and a more scale appearance. Yes it does suffer a little from bump steer, but no it didn’t really bother me as its an unavoidable foible you learn to live with when running this type of rig.

30
All that forward weight bias really aids climbing inclines and over objects

The wiring to the receiver may look like a rats nest but that’s the Spektrum receiver I used, It is waterproof and sealed with female ports protruding from it to accommodate male Futaba style plugs. Its a 3 channel RX so allows me to add a winch at a later date, plus there’s the power/batt in. I also opted to put in a 20A BEC kindly supplied by Phil at www.makeitbuildit.co.uk after first snipping and then isolating and insulating the red power wire from the Carisma RC branded Crawler ESC, thus bypassing its built in 5A 6v BEC.

The main reason for this is the possible current draw in Amps from the RC4WD Twister High Performance Waterproof Servo, and the fact that in use it may draw enough current to temporarily cause a Brown Out, even with (as I added) a glitch buster Capacitor!

RCCZ Jargon Buster: A ‘Brown Out’ is defined as when the receivers supply voltage falls below the minimum voltage specified for normal use. What that means in practice is that you will get at the very least unpredictable results, or at worst the link failing between the Tx and Rx and a possible run away unless the failsafe for the ESC is set to zero throttle…you were warned!

jwelcwhgfcl
That V8 billet engine at the front elevates this build from cool to epic!

With everything in place and the rolling chassis even drivable without it’s shell (yes, I couldn’t resist the good old sofa test!) it was time to move on to perhaps the most daunting part of the build for many…the body shell. Now, I knew that this Blazer body was far more detailed than any I had previously built from RC4WD, and to that end I decide top pay our resident hard body and airbrush maestro Jonathan Potts a visit. He’s more used to 1:1 Custom Cars, Speedboats and other such cool stuff, but his eyes lit up when I handed him the body shell and its box of bits.

My brief was simple:- ”Think classic Street Custom Car crossed with classic Off Road 4×4”…he smiled, and then disappeared into his workshop, past the VW Beetle chassis ready to become a Rat Rod, and the big 1:1 4×4 destined to be a comp vehicle of some sort one day…I drove away and then got on with other projects.

You can’t say RC4WD scrimp on components they offer with the body. ..

Many, many, parts are supplied in the box with the RC4WD Blazer Body . It has not only a metal hinged opening bonnet (Or ‘Hood’ if you are Scott AceofAxe Curlin), but also a hinged opening rear window built into the removable rear hard roof section over the flatbed, and even an opening tailgate. There also the brightwork, A chrome grille, wing mirrors, door handles and huge front and rear bumpers.

Included with the body kit is also an interior, but for this build I opted to tint the windows and not fit it. I know, I know, I can hear all the boo’s and hisses, but I simply didn’t have the time to get an interior done too, and I also wanted to keep the centre of gravity as low as possible, so any weight I could shed from above the centreline of the axles would be a bonus.

Clean Up In Isle Five…

After a two week wait, I got the call and went to collect the body. “Oh my god” was my reaction. (I hasten to add I did use those three words, but I may have added another…very much an expletive!). John had done what I had asked and, then added his usual flair and personal touches.

mhgdsxjhkj
John did an amazing job on the paint…he get’s it, he truly get’s it

After prepping the components he was going to paint he first laid down a deep burgundy, almost dark Autumn cheery red on the main shell, tailgate and bonnet. Then he painted in the side panels with black as an accent colour, but added an old-skool flame into the design and hand outlined the lot in silver. The result, while not being as perfect as using say a vinyl wrap, does look very real and authentic…decals can look too crisp at times.

Next he used a dark metallic brown to paint the rear roof section and a technique that’s akin to rag rolling. This builds up layers of paint and each is then flattened down to create, once top coated an almost leather look to the finished roof. It was stunning. I spent another day painting in window rubbers, adding in the other details like the metal K5 Blazer and Chevrolet badges RC4WD make, the grille detail and a few scale decals (including the RECON G6 ones RC4WD made for our event) and even a RCCarZone logo on the tailgate. Last I fitted the light buckets, painted the stop and turn indicators inside with Tamiya lens colour.

jhfgxcjhgfsdju
The spare and the decals and badging on the rear add top the depth of detail

Scale isn’t just about decals, or accessories, or paint, or wheels or chrome. Its about the combination of all the above elements working in harmony together to fool the eye into thinking:- “Real or RC?”. I think we achieved that with this build, and standing back a looking at it in various locations and natural backdrops, it looks stunning.

kkjtgdfjjhg
Look so realistic and has a stance that screams “Drive me!”

The final detail was adding the spare wheel and tyre to the tailgate. It just elevates the overall look to one of utter realism. I also ordered some scale number plates from a contact in the UK Scale Nationals Facebook group. They arrived just before we took the truck for its first trail run and outdoor shoot. It was run alongside the new Axial SCX10.2 and the rigs looked so good together.

55
One of my favourite views of the rig…(who am I kidding, I love it from all angles!)

Out Blazing In The Great Outdoors

I took the rig to our usual test venue in Warwickshire the same day we tested and shot the Axial SCX10.2. It’s a rig that you have to think about when driving, especially until you have fully broken in the leaf springs. You must always be aware that it is far more top heavy than a Lexan rig, but that’s where the fun lies. It’s realistic in both the way it drives and the way it looks, and you can’t say that of most 4-link Lexan rigs. They always seem to perform outside the parameters of their 1:1 equivalents. With the TF2 platform and this quite large and heavy body, you plan each line you take carefully, you see the way the rig reacts to the surface its running on, the angle of the incline or decent you drive it up or down.

28

With a hard bodies rig factors like Approach Angle, Break Over Angle and Departure Angle become far more critical as they are far less forgiving.

RCCZ Jargon Buster: Approach Anglerefers to the physical angle that If drive up to a object, incline or ramp, you can safely drive onto it without catching the bumper. If the incline is too steep, the rigs front bumper will hit the ramp first, before the tires are able to. The maximum angle (from the ground) that a hill or obstacle can have and that the front of your car can still clear is therefore called the Approach Angle. As for the Departure Angle, exactly the same principle applies, to the rear bumper and wheels of the rig.  For any scale rig, but especially a leaf sprung one like the TF2, when coming down off, say, a rock, or a small natural ledge, you have to know how much clearance you have under your car’s midsection, driveline and transfer box. The angle between your tires and the middle of your car’s underside is the Break Over Angle. If you get it wrong, you will end up balancing on a rock like a see-saw with most of your wheels not in contact with the ground.

21 (3)

One of the most important factors when running a rig for fun or in competition is traction, or the grip your tires have on whatever surface you’re driving on. Traction is produced by a combination of factors, by the type of tires you’re using, their size, and the type of inserts you use. Its also about how much weight from the rig itself is pressing down on them to create a contact patch of tread on your chosen running surface and how the suspension aids keeping the tyres in contact with the ground in relation to0 the rest of the rig.

31

large angles of articulation are out on a leaf sprung rig like this, and a phenomenon I personally call ‘Wheel Float’ becomes a regular occurrence. This is when the solid axles have surface contact and therefore grip with only three (or sometimes only 2!) tyres, and the other wheel or wheels cannot physically articulate enough via the suspensions range of movement to make contact with the ground. Don’t worry though, as You can very quickly get used to this and often use it to your advantage to use the rig to bridge itself between two objects, where a more traditionally spring rig may have fallen in.

23 (3)

Running a single speed transmission means that with a 35T motor fitted, the rig is a bout walking pace on 2S , and a brisk jogging pace on 3S. Run time however is very good and running a 2S 5000 mAh pack granted a good hour of trail running. On 3S you tend to be a little more trigger happy (or is that just me?) and thus run time is affected. 3s does however allow for additional wheel speed when needed, and with a rig of this overall weight you can build up a good momentum to get up a steep incline or even hop up onto a rock or object.

37

All of these factors are important when running a scale rig and must be accounted for in both its construction, and the way you drive it out on the trail or a comp course.

After 2 packs and just over 2 full hours I called it a day. I loved every minute of running the Blazer and it’s a totally different driving experience to any of my other current rigs. ‘Yes’, you feel a little more ‘concerned. that you will trash the paint on any more technical rock sections, and ‘No’ it didn’t stop me. I left Burton Dassett with a few chips to the paint, but nothing I couldn’t touch up. One thing I did find however is that the rear bumper did rub the body built stock, and therefore I used a cordless Dremal to grind the inner edge by about 1.5mm to offer a little more clearance between the two, then painted the scuffed area matt black to hide the damage.

“Additional Scale Points Go To The Blazer…”

36

In conclusion, the TF2 kit itself is simple and fun to build. Be as detailed or as simple as you feel you want to go, and take your time to threadlock and metal to metal union and grease all internal gears in both the transmission, transfer case and the axles. Choose electrics suitable for the job in hand, and make sure if possible the ESC, Servo and Receiver are at least ‘Splash Proof. Weight the wheels to lower the rigs Centre of Gravity.

When you enter into a build like this you have to realise what’s involved. It will take many hours to complete but it’s very, very rewarding. Hard bodies will always have the edge over Lexan in the realism stakes as they are solidly constructed and have actual depth to them and their panels. Lexan, while being dimensionally correct will never have this and always seem less three-dimensional. The Blazer is a rig I’m proud to take out to run, or let a buddy do so. It epitomises the scale scene at the moment and is a true snapshot of what RC4WD do best…help RC fans build their dream rigs!

A huge shout out to Tom and the RC4WD crew for the review sample and parts and to RCBitz in the UK for additional help with sourcing wheel weights etc.

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 !

13
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.

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
