Page 2: Important Notes
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. -

Page 4: Receiver Connection
CONNECTION Receiver Connection A3 Mini supports PPM and multi-protocol digital serial receivers which allows you to connect the receiver to the gyro with one single wire on the slot [Serial RX]. Depending upon the receiver type selected, A3 Mini uses the preset channel assignment to recognize the channels from the receiver. Refer to the table below and check if your radio transmits the channels in the correct order. - Page 5 Normal mode automatically and remote master gain will be disabled. Wing Type and Servo Connection A3 Mini supports Standard Fixed-wing, Flying-wing (Delta-wing) and V-Tail. Always turn off the mixing function of delta-wing or v-tail in the transmitter because the gyro will provide such mixing features by itself.

Page 6: Flight Modes
AIL and AIL2 are operated separately. FLIGHT MODES A3 Mini provides 6 flight modes which can be switched by using a 3-position switch of the transmitter during flight. The expected flight mode associated to each position of the switch can be specified via the configurator or the programming card. -
Page 7: Gain Adjustment
GAIN ADJUSTMENT Basic Gain A3 Mini provides separate adjustment of basic gain on aileron, elevator and rudder. Basic gain determines the reaction strength of the gyro. In general, the higher the gain the harder the airplane will stop after rotation and the more stable and precise the airplane will fly. But if the gain is too high the airplane will tend to oscillate at high frequency on the corresponding axis. - Page 8 An opposite reaction of the gyro could lead to losing control or even crash! Check the gyro direction for Aileron Quickly rotate the airplane left or right around the roll axis, the ailerons should react in the expected directions as shown below. WWW.HOBBYEAGLE.COM 8 / 12...

To improve we need to reduce the correction strength of the gyro on the desired direction dynamically when there is an input of the sticks. This function allows you to change the control behavior by choosing different curves of the gain attenuation. WWW.HOBBYEAGLE.COM 11 / 12... -
