Install the Rudder Servo

❏

1. Cut the covering away from the rudder servo opening

on the left side of the fuselage, in front of the stabilizer.

❏

2. Install a 16" [406mm] servo extension to the rudder

servo. Secure the extension to the lead with tape, a piece of

shrink tube or some other method to keep them from coming

unplugged.

❏

3 Install the rudder servo into the servo opening following

the same procedure used to install the aileron servos.

Connect the servo to the receiver, install and center the

servo arm.

❏

4. Place a mark on the leading edge of the rudder, 1-1/8"

[28.6mm] from the bottom of the rudder.

❏

5. Thread a nylon clevis 16 turns onto a 2-56 x 10" [254mm]

wire pushrod. Connect the clevis to a nylon control horn.

Position the control horn so that it is centered on the line from

the previous step. Mark the location of the mounting holes onto

the rudder. Drill a 1/16" [1.6mm] hole on the marks. Do not

drill completely through the rudder. Attach the control horn to

the rudder using two #2 x 1/2" [12.7mm] sheet metal screws.

Remove the screws and apply a drop of thin CA to both holes.

After the CA has cured, reinstall the control horn.

❏

6. Slide a silicone clevis retainer over the clevis. With

the rudder servo and the rudder centered, mark the rudder

pushrod where it crosses the rudder servo arm. Make a 90°

bend at the mark. Cut the pushrod 3/8" [9.5mm] past the

bend. Attach the pushrod to the rudder servo arm with a

nylon Faslink.

❏

7. Connect the flight battery to the ESC and check that all

the servos are operating correctly. Arm the motor (with the

prop removed) and slowly start the motor to make sure it is

rotating in the correct direction.
