Have experienced the same on some, not all of the ztw's. Before you take off, just trim throttle up so the prop barely spins. I had a 110 amp where the endpoints drifted while flying, so you would go low throttle and the the prop stopped. Have a 60 and 120 that are fine, no issues. I do have a steeper throttle curve dialed in my futaba 8fg. The Castle ICE 100's I run are a little smoother and run cooler.
