Hi All. Up to two or three years ago I had been flying all types of RC airplanes and helis for 15 years. For various reasons I stopped and recently decided to "step" back into it. Anyway, I have a Ultra Stick 60 from back then that I never put an engine on. I want to be able to hover with the plane and was wondering what would be a good choice of engine so aerobatics are only limited by my rusty fingers.
Looking for opinions, 2 stroke, 4 stroke whatever. I know many of combinations have been used so hopefully will get a good feedback.

Thanks
Z
