More Voltage = Less Amp Draw?

IF, you are gonna use it with a 540 sized motor, then you probably need to feed the motor with lots of volts to cut down the amp draw. Even Mike Franz, an official of Kontronik's technical department, said that it isn't really made for use in cars, despite the fact that it has two types of car programs.
I found that it thermals alot when you apply brake more often. Probably if you use mechanical brakes, that'll keep the controller much cooler. Either than that, this thing is smoooooooooooooth.

Shucks. I hope it doesn't thermal. You're not the first person to tell me this though. I will be running 10S to minimise amp draw and hope that will be sufficient. At 30V (3.0v/cell) and 65A, that's 2000W - well within its ratings. I thought about getting an MGM controller, but the Kontronik is cheap enough to risk it. I'm into RC helis too and I know the Jazz will be useful for a future heli if it ends up on the shelf with this experiment.

Glad to know it runs smoothly. I've read old posts about it cogging. I guess that was with old firmware. Cool!
