The Futaba PA-2 is a horizontal stabilizer designed for model aircraft that uses sensor technology to automatically return the aircraft to level flight when the transmitter sticks are released. It simplifies training by helping maintain level flight even if the aircraft enters a dangerous state due to wind or erroneous operation, though it does not automate takeoff or landing. The device operates by sensing the strength and contrast of sunlight to detect tilting.
| Power requirement | 4.8V (Nicd battery) |
|---|---|
| Current drain | 5 mA (at 4.8) |
The PA-2 recognizes tilting of the aircraft relative to sunlight and returns the aircraft to level flight by controlling the elevator and aileron servos.
The sensor will operate erratically, causing loss of control and creating a dangerous situation.
The system requires 4.8V from a Nicd battery.
It is recommended to install the sensor with the front pointing downward at 2 or 3 degrees.
