Thought I would get with the new age on a budget. Will be testing it out tomorrow

Looks very interesting. Can you post some more pictures of the car with the body off?

Hats off for doing something different. Doesn't look very tunable though. Are you going to proceed further with mods? Looks like a cool project

Thanks!! It can be just as tunable as a b4 but not a b5. I thought about doing a metal chassis, and different tranny, and shock towers from other kits. What would You do next?

I'm not familiar with that model, but it looks like it uses plastic camber links like Traxxas Rustler/Bandit. That would mean no camber adjustment, plus a lot of flex. If so, some adjustable turnbuckles would be the next mod. Some different shock towers to accomodate roll center adjustment would be a great tuning aid. And some shims or washers to allow anti squat adjustment. Most rear-motor designs have about 3 degrees initially. Mid-motors typically run 0-2 degrees to allow for weight transfer on acceleration. This should help with forward bite since you are running a 3-gear trans with no weight hanging off the back.

Just wondering...does the buggy feel nose-heavy on jumps and upon corner exit? Also, does it share servo with the Torment SCT? If it does, it's gotta go!

Adjustable turnbuckles are on the list for sure. I could probably find a shock tower to match or add more holes to the original tower with plate extensions. I may be able to put weight somewhere. New shocks hopefully soon

Changed out the servo today. Have not had a chance to hit the track so unsure.

New servo


Servo installed, pretty quick


Anyone know a front shock tower that is very similar to this? Looking for carbon fiber

Before I got to the track!



Found the last one in my area . Excited to try, it's the 17t speed gem short course motor. Geared 17/87 . 0 timing reverse rotation.

Hey, we ran those before we went brushless. Best bang for the buck in a rebuildable brushed motor. Well, that and the 13T Holmes motors. Hey, how is the front-to-rear weight bias? If it's nose heavy, you can always stick a shorty pack sideways just in front of the trans and move the electronics forward
