Thank you for purchasing our products. A3 Mini is a high-performance and functional 6-axis mini gyro
system designed for R/C airplanes. The smaller size and more compact design make it more suitable for
the small electric airplanes. With the new feature of multi-protocol serial receiver support, it could be
compatible with most single line mini receivers on the market. In order for you to make the best use of
your gyro and to fly safely, please read this manual carefully and set up the device as described below.
IMPORTANT NOTES
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 gyros 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.
After power on, A3 Mini needs to perform an accurate gyroscope calibration, keep the
airplane stationary after power on and wait while the LED flashes blue. The LED will stay solid
blue if a slight movement is detected and the calibration will not start until you stop moving the
airplane, however, making the airplane level is NOT required during the initialization.
A stick centering is also required following the gyroscope calibration. Always put all the sticks
center (the throttle stick in the lowest position) before power on the airplane, and do not move
the sticks until the initialization is done. The stick centering only applies to Aileron, Elevator, Rudder,
Aileron 2 and Throttle channels.
Make sure to check the gyro direction of Aileron, Elevator and Rudder after installation and
always perform a test of them before each flight. An opposite reaction of the gyro could lead
to losing control or even crash!
