i was not planning to jump to 3d, my question on engines is more related to power, i love to overpower my planes and was wondering if a .47 gms or a 70 4 stroke would give me a decent vertical. I think ill get the rapture and the somthin extra and have them be my winter projects (fly rapture first). i was thinking about a bigstick but thats basically what im flying now its a 2.5X2.5 pvc gutter pipe with coro for the wings( see pic)
