Just to echo some of the other posters about sync issues. I run a 63-74 Turnigy with a CC ICE 100 and rarely do I ever get sync issues. Oddly enough, I had worse sync problems running at a lower voltage (18.5v) than a higher one (22.2v) and that only occurred as I accelerated from a dead stop. Normally, I pedal up to 5mph or so before I start engaging the throttle.
