I am purchasing a GSP Hellcat.. I was trying to decide which motor to put in it. The plane weighs 10lbs, 70" WS... It calls for a 90 2C, or a 120 4C. Can I fly this on the RCV 90? I was seeing if I could get away with it, or should I get the RCV120? I want to use a 3-blade prop. Didnt know if there would be enough ground clearance with the RCV120 with a bigger 3 blade prop?

Any suggestions?
