well i tried the update on a novak hv 4.5 motor in the xt8 and it was much better as well, still cogged, but gearing way down may make it drivable but the kv rating is to high, the calc. said it was like 72k rpms and 85 mph, so i wont be running this!!!!!

cant wait till more reply, i think a neu is my next step, as long as it this fixes the cogging
