Tech Notes
This is a Pilot Assist Link (Auto Pilot) For Aircraft Use (Not Helicopters).
When You Release The Transmitter Sticks, The PA-2 Automatically Returns
The Aircraft To Level Flight Even If It Enters A Dangerous State
Due To The Effect Of Wind Or Erroneous Operation.
This Simplifies Training In Model Aircraft Flying Techniques.


This Is A Horizontal Stabilizer For Model Aircraft and Incorporates
The Latest Sensor Technology.
Operates On A Single Aileron Servo.
Supports two Channels To Level The Wings and Bring Plane To Level
Automatically Controls The Elevators and Ailerons, But When The
Modeler Operates A Stick, The Sensitivity Drops According To The
Amount Of Stick Operation and Stick Operation Has Priority.
Sensitivity Can Be Adjusted By Transmitters Having Volume Control-
(At Least 5 Channels and At Least One Extra Channel Is On A Dial.)
(See COMMENTS) Or By The Gain Control On The Amplifier Unit Itself.
Some Radios W/Volume Control Are: SKYSPORT 6VA, 6XA, 7UA, 8UA, 9ZA.
Other Brands Of Radios May Work If They Are Wired Like And Have
Connectors Like Futaba Has.

PA1 had a slot for the second Aileron Servo. Customer must use a
"Y" connector for the second Aileron servo with the PA2.
The Gain on the PA2 can be adjusted directly on the unit itself
and thus does not require a transmitter with Volume control.
