Hey Hal !! I'm using CJ's retracts. The wheels(4 inch) are sitting into the wing pretty good and I dont see any way to get them to sit any deeper.Maybe I could take out the 2 wing ribs that are in the wheel well and that "may" give me another 1/4 inch or so of depth but no more.Are you guys seeing that you had to totally remove the 2 ribs(and have nothing but the upper balsa sheeting for the wheels to touch) to get yours to operate correctly?
Thanks!!
John
