IMPORTANT NOTES

A3 Pro

INSTRUCTION MANUAL

Aug 1, 2017 Revision

1. Radio controlled (R/C) models are not toys! The propellers rotate at high speed and pose

potential risk. They may cause severe injury due to improper usage. It is necessary to

observe common safety rules for R/C models and the local law. Read the following

instructions thoroughly before the first use of your A3 Pro and setup the gyro carefully

according to this manual. We also recommend that you seek the assistance of an

experienced pilot before attempting to fly with our gyros for the first time.

2. Always turn on the transmitter before power on the plane and the gyro. After Power on, A3

Pro needs to perform an initialization which includes the gyroscope calibration and stick

centering. Keep the plane still and wait for the gyro to initialize, the initialization will take about

2 seconds and the LED will blink blue several times. Don’t move the plane and keep all the

sticks in their original position until the initialization is done. After a successful initialization, the

aileron servo will give you a short up and down move. If the LED retains solid blue, stop

moving the plane then the initialization will start automatically.

3. Always check the gyro direction for each channel before takeoff. An opposite reaction of the

gyro could lead to losing control or crash during flight!

4. Never use a very small gain setting or master gain when flying with the gyro in Trainer mode,

or it will lead to a weak control or even losing control of the plane.

5. When flying, you can fine tune the surfaces by turning the trimming buttons on the transmitter

as before, this is allowed. However, we still recommend that always adjust the center position

of the servos by using the “servo trimming” function provided by A3 Pro if possible.
