decrease your elevator throw until the wing drop stops, otherwise if you get in a bind too close to the ground and yank full up elevator you might just snap the the plane in the ground. usually 12-15 degrees of elevator is about max that planes of this type will tolerate before snapping in normal aerobatics, and you have to get into the 35 - 45 degree range for 3D. any where in between and the plane will fall off.
