Well restoration is finished did maiden flight, upssssss very nose heavy have to put weight on tail, one thing I didnt liked is that plane tends to go left side during loops, and rolls to left side become a bow instead of roll, took a close look to left aileron and its not straight, have to adjust it, a friend told me to put a small piece of balsa where wing wears in fuselage on the opposed part of tendency to correct this , im not sure I want to do this and even if it will help at all, my question is ; is this the cause for this awfull tendency ? it also fights to keep knife edge, plane tends to sink, will this change as soon I fix the balance?

I think it would be a good idea on starting a thread called "Pattern plane set up" anybody interested on starting it?

Txs for your advice is a nice plane and would like it flying well.
