I am finishing the build on an AV8R turban jet. It has a foam core wing that is sheeted with balsa. It has flaps and ailerons, so it needs 4 servos in the wing totoal. But HOWDOIMOUNTTHEM!? There is nothing but the 1/16" balsa sheet and foam to screw them into. Sence this thing will fly at 150-200mph I want them to be very strong! Im not much of a scratch builder, so I dont kow many little tips and tricks. The only thing i've thaught of is to epoxy a hardwood block into the foam and screw the servo to that. But im worried about fatige of the foam being able to hold the wood after a while.

Anyone had any experiance with this plane or have any ideas?

Thanks!
