Kevin, i'd say the DA85 would be a good choice. I've also seen them fly on zenoha GT80's pretty fast too. depending on how much you want to spend you could also look at the RCS 150 Radial if it would fit i think it's diameter is around 8.5 " that would be pretty KICK-*****. It is 10" in diamiter sorry 150 cc way to much for this plane.
