-Tears of Joy-
It purrs like a dentist's drill, with the whole drivetrain(motor, wheels and gears) hooked up to a 6volt lantern battery and under low loads. The final project will be 7.2V. It should have at least the same torque as the un-modded ZZSE, but hella fast. The wheels arn't stopped very easily with fingers.
Going that fast it started to smell like burning plastic, not electronics or motor. I need to start lubing the gears and axle generously. Next time I do this: metal gears, ball bearings. I can't wait to get this thing on the ground and under control and get a m.p.h speed. I'm using blue gears so far. I think the gym floor is the only place i can drive this.
All I need is a relay or large FET that will trigger with the current I mentioned earlier and can handle 7.2V. I think I will mod the relays that I have, tonight, to serve this purpose.
This has got to go at least 12 m.p.h.

(?????) By the way what is the speed to beat? How are you guys measuring it ("quarter-mile", unlimited head start)?
