You are going to love that plane. I had a Quadra 72cc on mine and it was a ball. I did enlarge the rudder a great deal though, at least double in size and beefed up the landing gear to handle the weight of the engine. I found that the upper wing needed to be at about 1.5 degrees LESS angle of attack than the lower wing for best flight characteristics. Just a minor difference in the relative incidence made a big difference in how it flew.
