Installing Horizontal Tail and

Pushrods on Control Horns

Installing the Horizontal Tail

1. Put the horizontal stabilizer tube in the round hole

located in the horizontal stabilizer slot of the

fuselage.

2. Slide the left horizontal stabilizer onto the

stabilizer

tube.

3. Slide the right horizontal stabilizer onto the

stabilizer

tube.

Note: Make sure the elevator joiners interlock with

each other, allowing both elevators to move together.

4. Secure each horizontal stabilizer with the included

machine

screws.

Installing Pushrods on Control Horns

CAUTION: The installation positions of the

pushrods and clevises directly affect aircraft

response. When these are incorrectly connected for

the pilot’s skill level, unexpected aircraft response to

controls can result in unintended crash damage to

the aircraft.
Note: The elevator and rudder pushrods come with a

nylon clevis already installed and a 90˚ bend

already bent.
Elevator Pushrod Installation
1. Locate the 6 1/2-inch (165mm) pushrod.
2. Carefully spread the clevis and put the clevis pin

into the hole in the control horn.
Tip: You can thread the clevis in and out to shorten

or lengthen the pushrod. Make sure transmitter trims

and sub-trims are centered before making mechanical

adjustments.
3. Slide the 90° bend into the third hole from

the

screw.

4. Snap the 90° pushrod keeper on the pushrod. This

holds the pushrod to the servo arm.
Rudder Pushrod Installation
1. Locate the 7 7/8-inch (200mm) rudder pushrod.
2. Carefully spread the clevis apart and slide the pin

into the control horn.
3. Slide the 90° bend of the pushrod into

the outermost hole on the servo arm.
4. Snap the 90˚ pushrod keeper on the pushrod. This

holds the pushrod to the servo arm.

Note: Not to scale.
