􀀀 􀀀 Step 4
Use sidecutters to remove the excess servo arm
beyond the enlarged second hole.
􀀀 􀀀 Step 5
Remove the ap hatch from the lower wing. Note
the orientation of the hatch by the black portion of its
covering. Position the servo as shown with the bottom
of the servo 1/8 inch above the outboard edge of the
hatch, and centered fore and aft.
􀀀 􀀀 Step 6
Use a pencil to mark the servo mounting locations on
the hatch.
􀀀 􀀀 Step 7
Mix a small amount of 30-minute epoxy and glue the
10 x 11 x 20mm mounting blocks to the hatch. Orient
the blocks so they do not protrude beyond the edge of
the hatch.
􀀀 􀀀 Step 8
Place the servo on the mounting blocks with a 1/32-
inch gap between it and the hatch. Use a pencil to
mark the mounting hole locations.
􀀀 􀀀 Step 9
Use a 5/64-inch drill bit in a pin vise to drill the servo
mounting holes. Apply a small drop of thin CA to each
to strengthen the wood. Allow the CA to cure without
using accelerator.
