Hi Tom, glad you are doing a build , not many going on these days. If I was doing a sport plane I think I would cut 1 or 2 bays off each wing. Back in the late 80s I did a tower trainer 60, made it a tail dragger and cut 2 bays out of each wing. I put a ST 90 on it and added a lot more rubber bands to the wing, it ended up being one of the best flying planes I ever had, they are a lot of fun.
