no, it actually fly's nose heavy when fueled. He is wanting to slow it down on all aspects. like in the patern and on aproach. We curently fly on half throttle. today I flew a 11X5 prop and on a bad landing I brok it. the only other prop i had was a 11X6, and I really see the diffrence. the 11X5 made a better beginner performance, but the 11X6 gave me unlimited climb.
