Hello Guys. Here are a couple of photos showing how I plan to treat the flap servos. The first shows the cover in place using four small servo mounting screws to hold the access plate in place. Simply remove the screws and the access plate with the servo mounted to it drops out of the bottom of the wing.
I used basswood for the plate and reinforced it on both sides with light glass cloth and epoxy being careful to dab off the excess epoxy. That made it stiffer and stronger.
The second photo shows the servo mounted to the inside. It butts up against the rib and is secured by two posts that the servo mount screws go in to.
I made the servo control arm cutout after I fired up the transmitter and receiver and centered the servo. Then I placed the arm in the correct position. Then I made the hole just wide enough for the arm to move freely.
The black that you see on the trailing edge behind the ribs is a strip of .014 carbon fiber. Just some insurance....

I will duplicate this process on all four flap servos.
