LJ 9. Install the metal rods in each balsa pushrod.

Wrap the ends of the pushrods with heavy-duty

button thread and apply epoxy to hold the thread in
position and add strength. Set the pushrods aside to
allow the epoxy to cure.

Q 3. Place a spacer made from leftover 3/32"
balsa sheet between the rudder and elevator servos.

Mount the servos on the servo rails using the screws

provided with the radio system. Remove the spacer

after the servos are mounted. Wrap the receiver and

receiver battery in foam rubber and place them in
front of the servos.

Q 4. Drill a small hole in the side of the fuselage

next to the receiver. Route the receiver antenna out

the hole and attach it to the vertical stabilizer with a

rubber band and T-pin.

Q 5. Install the receiver switch in the side of the
fuselage and connect it to the receiver and receiver
battery.

Q 1. Place a couple of pieces of leftover 1/16"
balsa sheeting in the bottom of the radio

compartment to raise the servos. Install the rubber
grommets and eyelets on the rudder and elevator
servos. Set the servos in the radio compartment. Test
fit the aft 1/4" x 1/2" x 2" basswood servo rail in
position. The rail should be snug against the
fuselage sides, but not so tight that it causes the
fuselage sides to bow outward. Once you're
satisfied with the fit, use 6-minute epoxy or aliphatic
resin to glue the aft servo rail in place.

Q 2. After the epoxy cures/ test fit the forward

1/4" x 1/2" x 2" basswood servo rail in position

and glue it in place.

U 6. Drill a 3/32" hole 1-1/8" from the end of
both balsa pushrods. The holes should be on the
same sides as the holes used for the threaded rod.

Cut a groove from each hole to the end of the
pushrod. The groove needs to be wide enough for
the leftover metal rod to fit in.
