hello all must say i have probably learned a good lesson, now maybe some ideas on how to fix it. I have built my servo tray a little to high on my 4*40 and the throttle servo and the aileron servo hit each other when the plane advances to 3/4 throttle which puts it in a left turn not recoverable until you pull the throttle back to half the aileron servo frees up again and you have complete control, im trying to think of a easy fix here which i was thinking of just trying to flip the servo around on the ailerons or shave the hardwood brace down some to give me the space i need for full throttle, and recess the aileron servo almost in the wing center section, i know there are alot of 4*40 fliers out there so any input would be good thanks mike
