No a1pcfixer, I tried that last week. Firstly I need to move the tank all the way back to the wing tube to try and get the CG. Then as you suggested, I would move the throttle servo forward to be flush with the canopy bulkhead. In fact, I even cut the ply that I was going to use. But just under that switch is the hole for the wing bolt. In this airplane, the wing bolt is tightened from inside. So if I move the servo forward, I cant get to the wing bolt. Thats the reason why I had to post for help again
