Great Planes RV-4 Park Flyer Kit - GPMA0010 - Manual (Page 28)

the fin is aligned with the rear of the fuselage. Glue the stab
to the fuse with thin CA. The photo shows the rudder
installed on the fin, but your model will not have the rudder
installed yet.
❏
8. Place the rudder over the plans and mark the location
of the tail wheel wire where it mounts on the rudder. Drill a
1/16" [1.6mm] hole in the leading edge of the rudder for the
wire. Notch the leading edge of the rudder for the wire to fit
into. Insert the tail wheel wire in the rudder and make sure it
is aligned correctly. Make sure the model will track correctly
on the ground with the rudder centered. Glue the tail wheel
wire into the rudder with thin CA.
❏
1. Before proceeding, charge the motor battery (and your
transmitter if needed). When it’s time to set up the radio you
won’t have to stand by while the batteries are charging.
❏
2. Cut the covering from the elevator and rudder pushrod
exit slots near the aft end of the fuse. Push the rear ends of
the pushrods out the slots in the rear of the fuselage.
Refer to this photo for the following four steps.
❏
3. Install the left elevator on the fuselage. Insert the
elevator joiner in the slot behind the stab and check that the
elevator will move freely once installed. Hinge the left
elevator to the stab using clear cellophane tape as shown in
the sketch that follows.
❏
4. Connect the front of the elevator pushrod to the servo
arm, then mount the servo arm to the elevator servo. Connect
the other end of the pushrod to the outer hole in the elevator
control horn, then insert the control horn into the slot in the
elevator. Glue the control horn into place with thin CA.
❏
5. Slide the pushrod end in or out of the pushrod tube
until the elevator is centered when the servo is centered.
❏
6. Hinge the right elevator to the stab using clear cellophane
tape. Glue the 1/8" [3.2mm] elevator joiner to the right elevator
with thin CA. Make sure the left and right elevators are aligned
before gluing the joiner into place. Be careful not to glue the
joiner or the elevator to the stab or fuselage.
❏
7. Install the rudder to the fin with clear cellophane tape.
The rudder pushrod should be inserted into the inner hole of
the rudder control horn.
❏
8. If you have not done so already, attach the ailerons to
the wing with cellophane tape the same as you did the
elevators and rudder. Follow the instructions on page 14,
“Build the Ailerons” for pushrod installation.
❏
1. Install the supplied 3/4" [19mm] tail wheel on the tail
wheel wire. Hold it in place with a white nylon retainer.
❏
2. Install the supplied 2" [51mm] wheels on the 3/32"
[1.6mm] wire landing gear. Secure the wheels with the
supplied wheel collars and set screws.
