3. Prepare a 5/64-inch (2mm) drill bit by wrapping
a piece of low-tack tape around the drill bit 5/8-
inch (16mm) from the end of the bit. This will act as
a marker so you don’t accidentally drill through the
top of the wing. Place the drill bit in a drill.
4. Use the drill and drill bit prepared in the
previous step to drill the four holes for the landing
gear block or retract mechanism mounting screws.
5. Remove the landing gear block or retract
mechanism from the wing. Use a #1 Phillips
screwdriver to thread a 3mm x 14mm countersunk
self-tapping screw in each hole to cut threads into
the landing gear rails. Remove the screws after
threading the holes.
