I've run 2 packs through it so far and its a blast. Only onroad though at the moment. Trying not to kill the tires before I get it finished!

I didn't take into account tire ballooning when I did the gearing calculations as I didn't think it would matter. So from a top speed of 39.77 mph (63.88 km/h) @3.7 Volts/Cell which is what I aimed for, it goes to 58.38 mph (93.78 km/h) @ 4.2 Volts/Cell with ballooning! I don't think its going quite that fast but it gets along. I'll get someone to video it soon.

Its the first time I've balanced the wheels on it too and WOW! I put an unbalanced set on for the first test and it shook the car at 1/4 throttle. With the balanced wheels it'll sit solid on a stand at full throttle. Amazing difference.
