hole in the arm that is 5/8-inch (16mm) from the center of
the arm.
56. Check the fi t of the M3 x 10 pan head screws through the fl ap
mount. Measure the length protruding from the mount. If this
measures more than 5/32 inch (4mm), use washers under
the head of the screw to prevent the screw from penetrating
through the wing sheeting.
57. Mount the fl ap servo in the wing using the M3 x 14 pan head
sheet metal screws and a #2 Phillips screwdriver.
 We recommend installing and removing the flap servo, then
hardening the screw holes in the wing with thin CA. This will help
reduce the change of puncturing the wing using only the screws.
