No problem at all. In fact most AFRs do it that way now.
The easiest way to do it is to sheet an area between two ribs (Instead of using cap strips) Cut out a hole for the hatch, but make the hatch itself out of 3/23" ply. Then add a plywood strip to each side of the hole (On the inside) to screw the hatch to.
Epoxy two hardwood blocks to the hatch to mount the servo to and cut a slot in the hatch for the servo arm
make sure you cut the slot large enough so the arm AND the clevis can move freely.
I had planned on mounting the servo to the wing with a hatch to cover it. Your pic show the servo mounted to the actual hatch.
My idea attaches the ply servo mount to the wing spar and rib making it more secure??? mounting the servo to the hatch is easier but the hatch will only tie into wing sheeting or ribs. (not as solid as the spar) ??? how is it usually done on the ARFS? not sure how strong this has to be?
Thanks
