AERO330LX,
profile servo installs are really easy. i throw away the mounting instructions and mount servos to hatch using small hardwood rails of the correct thickness for the out put arm to stick tru to the correct height (usually top of case has to be flush too under side of hatch ,or just slightly recessed). then when you remove hatch servos come with it leaving everything accessible.hatches are 1/16 ply rails are far enough out so screws holding hatch in place don't split it. then harden screw holes with thin c.a. have done this on my knife (75 flights) and my taco...if you would like i think i have some pics i will dig them up.
