I wouldn't doubt it, it's just the temprature problem, trying to keep those little demons down to a decent temp. How hot did it run? and how fast?

I remember lot's of ppl used to use Lehner Basic's, they went pretty dang fast too, about 35mph tops.

IMO, I think we can, and should be using small motors... it's just a matter of getting the most ideal turns, voltage, and efficiency curve. I've seen the Lehner motors have much different eff. curves with diff # turns/voltage. EX. The 3080/40t on 100 volts has VERY higher efficiency at lower torques, and drops off slightly as you increase current (torque); the same 3080 with 15 turns running 50 volts has fairly low efficiency at lower torques (current), but gradually increaes as you up the current. It all depends on what is required more, and what kind of duty cycle is observed, like acceleration/cruising to get the best AVERAGE efficiency, thus power consumption.

But really, as long as a motor is suitably sized, you will have very decent efficiency, if you want to go the extra mile and score a few % points, for extra runtime, or cooler running, or less weight due to less batteries needed, or whatever. That's what makes this sport so addicting :004: , and frustrating at times :031:
