Install The Radio, Servos & Pushrods - GREAT PLANES RV-4 Instruction Manual

If you will be installing LiPo batteries skip ahead to, "Install
the Radio, Servos, and Pushrods." Follow the instructions
as they are written. The only difference will be that you
should install the battery and receiver into the rear tray that
you just installed.
If you are installing NiMH batteries skip ahead to, "Install
the Radio, Servos, and Pushrods." Follow the instructions
as they are written with the following two exceptions. When
you are instructed to install the receiver and battery, install
them in the secondary receiver/battery tray you just
installed. When you are instructed to install the servos,
install them into the secondary servo tray you just installed.

16. Install the throttle servo into the tray in the fuselage. Drill
a 1/16" [1.6mm] hole through each of the mounting holes in the
servo. Install and then remove a servo mounting screw into each
of the holes you have drilled. Apply a couple of drops of thin CA
into the holes to harden the threads. After the glue has
hardened, install your servo. (Note: Included in the kit are four
1/8" x 5/16" x 3/4" [3 x 8 x 19mm] plywood spacers. Later in the
manual when you are instructed to install the battery and
receiver, you may need to use the spacers to raise the throttle
servo to provide enough room for the battery.Your choice of battery
will determine whether you need to use the spacers or not.)

17. Install a brass screw-lock pushrod connector and
nylon retainer to the servo arm. Slide it onto the pushrod
wire, center the servo, install the servo arm onto the servo,
and then install the servo screw into the servo and a 6-32 x
1/8" [3mm] SHCS into the screw-lock pushrod connector.

1. Locate three .095" x 36" [.095" x 914mm] pushrod wires
threaded on one end. Slide two of the wires into the two plastic
pushrod tubes in the center of the fuselage. Push them into the
tubes until they touch the covering on the outside of the
fuselage. Cut the covering away to allow the wire to exit the
fuselage side. Do this for both sides of the fuselage.
❏
2. Install a threaded metal clevis onto the threaded end of
each of the pushrod wires approximately 20 turns.
❏
3. Connect a nylon control horn onto each of the two
clevises. Position the control horns on the elevators,
positioning them on the plywood plates the same way as
