site down your ailerons trailing edge. Mine was warped pretty bad. I had to take the trim off the top of the aileron and wet the aileron down with water and ammonia. From here I laid a 4 foot level on top and bottom of the ailerons with 4-10 lbs weight plates on there and let it dry over night. Now I have a straight aileron trailing edge. also check the wings indence with a meter mine were off when I put the plane together.
