I was going to post these photos last night, but when I did they were giant on the page.
here is the plane I was refering to,my Gizmo sport plane, oversized barn door ailerons, rudder,and elevator, the fuse sides are 1/8" balsa sheets, and the screw holes are strengthened by some small pieces of 3/16" balsa stock the holes are hardened by the thin CA like I mentioned in my earlier post.
there surprisingly strong, really no need to go overboard with making servo mounts overly heavy, strong yes of course, but adding exessive wood is really not necessary, as long as the structure is sound at the mounting area, and the hole is the exact size of the servo body this helps counteract the torque of the servo, the screws really just hold the servo in place.
a pre crash photo, and its new red color scheme, had to rebuild the front of the fuse and recover the wings after a little mishap all good now
