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 …
Big Similarities – Subtle Differences
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
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.
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.
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.
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!
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.
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…
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.
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!
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.
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 !
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.
Testament to Carisma, no damage, apart from a few scratches to the shell, which has to be expected when playing on concrete.
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!
