A while back someone here (I think it was R Ray) pondered what the output of the Rokuhan throttles looked like. Well, for my RC-02 it's a .3 to 10V DC output with a 12 V 25kHz pulse superimposed with a 0.5 to 5 uS width. Before anyone starts to panic about the 12V, the frequency is too fast and pulse too short to apply any significant power to the motor. It seems to be used more to drive LED lighting than to drive the engine. It looks like this mid-throttle: I'd be interested in reading any results for the other Rokuhan throttles. Mark
