RE: ultra stick lite engine choice
if you can get a homelite 33CC from a chain saw go for it you will see and feel the extra torque and power I have one on a Ryan's Rebel that I sell and I can do anything that you ask on that plane (80" wingspan, 12-13 Lbs weight, 1300sq. in. wing area) these engines are very easy to convert and install I use a conventional Plastic engine mount, I'll see if I can post some pictures with my daughter's camera.
