Overview:

The A3 EVO is the latest 6-axis gyro for airplanes, which is developed based on AVR platform and applies the high efficiency, concise and mature algorithm. Experience with previous gyros and introduces many new features such as PPM receiver support, separate 3-axis basic gain adjustment and the throttle output channel for mini serial receivers. The A3 EVO provides users with more powerful and better performance.

Flight Modes

A3 EVO provides 4 flight modes which can be switched by a 3-position switch of the transmitter during flight. The color of the LED shows the current flight mode of the gyro while in use, as shown below.

We provide you with 4 different mode allocations corresponding to the 3 positions of the switch in Item 7 of the Setting Menu,

the default setting is MODE 1: NORMAL – LEVEL - HOVER.

GYRO OFF Mode

When operating in GYRO OFF mode the gyro will be deactivated completely, and the airplane will be completely under the control of your transmitter as it was before installing the gyro. This mode is usually used for testing purpose only.

NORMAL Mode

The NORMAL mode, also known as the "Rate mode", is the most basic function of the gyro. It works based on the rotation rate control of each axis of the airplane. When operating in this mode, the gyro will only correct currently occurring rotational movements, a momentary reaction will be applied to the servos when the airplane rotating on corresponding axis, after rotation the servos will move back to their neutral position as soon as the airplane standing still immediately. The NORMAL mode can be used with nearly any size and type of airplanes. It can effectively improve the stability and precision of the airplane and reduce the stall point specially.

LEVEL MODE

The LEVEL mode is also known as the "Auto-Level mode", "Auto-Balance mode". When operating in this mode, the airplane will be brought to horizontal position automatically when releasing the sticks. Different from the ANGLE mode, there is no maximum angle limitation in this mode and the airplane will be stabilized only when there is no specific control input from aileron and elevator sticks. This mode can be used if the pilot becomes disoriented and would like to save the airplane from crashing.

HOVER MODE

The HOVER mode, also known as the "Auto-Hover mode", provides the same functionality as the LEVEL mode. The only difference is that when you release the sticks, the airplane will be brought to vertical position (nose up) and keeps hovering. This mode is designed to help you to learn hovering maneuver and reduce the probability of crashing.

Standard PWM Receiver Connection

Notes:

- [MODE] is used for flight mode switching of the gyro, connect it to a 3-way switch channel of the receiver to switch the flight mode in flight.

- [SBUS/PPM/G] is used for remote master gain adjusting, connect it to a proportional channel of a volume or slide lever of the transmitter to tune the master gain in flight.

- The ESC or throttle servo is connected to the throttle channel of the receiver directly without passing through the gyro.

- Pay attention to the polarity of the plugs. The orange signal line must always be on the top and the brown on the bottom.
