I built this axle out of broken parts in about 15 minutes. It scoots around fairly quick on 5 volts and has plenty of torque. The actual axle is from a fried zip-zap monster truck that has been cut up a bunch and has had the 4 wheel drive driveshaft removed. The motor is a servo motor and the esc is a modded servo board from a stripped servo. It is fully proportional with forward and reverse (no brake). I still need to shorten the motor wires. Eventually I want to add a micro servo for steering and run everything off a rechargable receiver pack, maybe fit everything under a model car body and give it to my brother as a b-day present. Yes I'm cheap Just thought Id show you guys, and opinions are always welcome.

Edit: Sorry for the blurry pics, this camera doesnt have a macro mode.

That's really slick. It's amazing how versatile the electronics inside a servo can be.

Nice work!

wow its tiny! pretty cool that you can amke something like that in 15 minutes

Lol, the rear took 15 minutes, the fronts going to take me forever.
