i did check the cg according to the lines on the bottom of the wing,its tail heavy with the weights added to the rear of the fusalage.the repairs were done to the fusalage where the wing bolts to,it wasnt real bad but where the bolt goes through was busted right off.i didnt make the repairs,a friend of mine did and he says the repairs shouldnt have anything to do with the problem im having??i dont have any of the training gimmicks on,they have been off since day one including the afs.
