D 4 Without cutting into the balsa, use a sharp hobby knife
to carefully cut and remove a strip of covering 1/16" wide,
approximately 1/32" inside of the line you made Wipe away
the line with a paper towel dampened with alcohol.
D 5 Reposition the canopy on the fuse and confirm that it
covers the exposed wood Glue the canopy to the fuse with
a glue formulated for gluing on canopies such as Pacer
"Formula 560" canopy glue Hold the canopy in place with
masking tape or rubber bands.

them apart as necessary so the servo arms do not interfere

radio system, turn to page 44 and check the balance point
of the plane The radio tray can be installed with the servos
forward or aft If the plane is tail heavy, install the servo
tray with the servos forward ^ If the plane is nose heavy,
install the servo tray with the servos aft. D 4 Plug the servos into the receiver Wrap the receiver in
foam padding and rubber band it in the servo tray Insert
the servo tray under the outer pushrod tubes and glue it in
position Install the receiver switch and plug the receiver

tray is installed as far forward as possible, even with the
servos at the aft end.
