RE: What is a good intermediate 50cc imac plane?
Skypilot.
that plane will be excellent for basic and higher. I had that plane last year and moved the CG 1/2 inch forward of the recommended spot and it turned it into a whole new plane. I worked out the thrust issues and downline trim and KE mixes and the thing flew last years Basic and Sportsman like it was on rails, I was stoked. On the day before the first contest I was practicing in 25mph winds and landed in a sideslip (didn't get the slip out fast enough) and tore the gear out which proceeded to tear the plane into little pieces.
I will say that next to my C-Arf 3M it had to be one of the better 50cc IMAC planes
