my q35 turns a 18-6 wood zinger at 8000. point cap calls for .015. at .016 it would only turn 5600 & sounded sick. set them at .014 and the motor came alive. i haven`t tried any other prop. it`s on a h-9 supercub & it will almost hover. a cub looks funny going straight up for a couple hundred feet. i`m real happy with it . i only paid $100 for it.
