Step 4
Install the rubber grommets and brass eyelets in the servo
according to the instructions provided with your servo or
radio instruction manual. Use the radio system to center the
aileron servo. After removing the stock servo arm, install the
180-degree servo horn that was prepared in the previous
step. Note the direction of the arm in relationship to the
servo and servo cover.

Step 5
With the arm centered in the opening in the servo cover, use

Step 6
Use medium grit sandpaper to roughen the servo mounting
block where it will fit against the servo cover. This will
improve the surface for bonding the epoxy in the following
step. Make sure to sand the end grain of the blocks.

Step 7
Use 30-minute epoxy to glue the blocks to the servo cover at
the marks made earlier. Use clamps or tape to keep the block
tight against the servo cover until the epoxy fully cures.
Important: Make sure the blocks are at least 1/16-inch
(1.5mm) from the edge of the servo cover. If not, the
cover may not fit back onto the wing as the blocks will
interfere with the fit.

Step 8
Position the servo on the servo cover. Leave a small gap of
1/32-inch (1mm) between the servo and cover so vibration
won't be transferred through the cover and into the servo.
Use a pencil to mark the locations for the four servo
mounting screws.

Step 9
Use a drill and 1/16-inch (1.5mm) drill bit to drill the
four holes on the blocks for the servo mounting screws.
Place 2 to 3 drops of thin CA in each hole to harden the
surrounding wood.
