Everyone in our club clips a one bay off of each side of the wing. Also, we prop up the back of the wing with 1/8 ply to take away some of the incedence. Makes the plane not climb so much when on the throttle. I used two servos in the center of the wing with the stock torque rods, then set up flaperons on my radio. Works great for carrying heavy bomb loads, or when I have the floats on it.
