Which Controller for My Application?

Granted. But I don't need excessive oz-in...which is why I've read about other's experiences (which are very subjective and relative to many person dependent variables) and graph motor performance w/ various voltage/current combinations. Oddly enough I'm thinking the Lehner's are a great choice (based on user experience) even though I can't put their specs into my calculator.

The xl3100 will run a bit hot at that voltage and will be too powerful to handle in my opinion. As I said, the xl2400 on 22.2 volts will achieve your speed desires with the proper gearing, but will run cooler. The xl2000 would be my choice. ASgain, this will provide plenty of speed/power, but will have better runtimes and cooler operation vs. the xl3100. I doubt you will see 50 mph on a racetrack anyways (40mph if your lucky).

I don't wanna run my motor too hot as I'd like to run in the long mains, so I'll bump it down to the 2800.

I'll stick w/ the stock gearing for now and see how I like the performance & runtime.

The LiPo's and speed control are the expensive components, I don't mind getting a different motor to alter speed/torque/runtime/temps if I don't like the 2800. :)


thx!
