Evollution has a new engine - .60NX - it is a .60 in a .40 size. This hobby is so addictive I tell ya. I'm itching to give the new Evolution .60NX a try. I have a SuperTigre G-51 with a pipe on a small 4lb 11oz plane and I'm thinking about putting one of these on it and give it a try with maybe an 11x7 or 12.x6 prop.

Anyone have one of these? RPM numbers? Prop recommendations?
