Example:

Castle Neu 2200kv on 6S versus Castle Neu 2200kv on 4S

The 6S setup is "tamed" with torque control and throttle limiting to mimic the performance of the 4S setup. But the 4S setup is set to "all out" performance. Both setups geared the same in.......ummmm........let's say an E Revo.

The switching of the fet's on the powerboard will still conduct the full pack voltage, only the "off" time will be longer than the "on" time with 6S, compared to the 4S setup.

#3. I'm also wondering if these "tame it down" settings would allow using higher kv motors on higher than rated voltage?

Temperatures being the overall guide, of course.
This was a copy and paste job from sikeston and I would love some input on this
#1 - yes
#2 - not usually... there is some efficiency penalty when running at less than full throttle -- so if the 4S system is running a higher percentage of full throttle PWM, it will run more efficiently.

#3 -- not what it was designed for. And remember, most of the time RPM is the limiting factor with motor ratings - -and torque control doesn't limit RPM.

thanx!
