Caution Notes

 Thank you for choosing our products. If any difficulties are encountered while setting up or operating it, please

consult this manual first. For further help, please don’t hesitate to contact us via email

[e-mail].

 Before power on, put the aileron, elevator and rudder sticks in the middle position. The controller needs to

perform self-calibration and stick centering after you plugging the battery, the LED will keep blinking Blue

rapidly for about 3 seconds while calibrating, don’t move the plane and the sticks until the initialization is done.

 It’s extremely important to verify that the gyro reacts in the correct direction before flight, or it could lead to

losing control or even crash during flight!

 You need to restart the controller after changing the receiver type to make new setting take effect.

 Never use the delta-wing or V-tail mixing functions of your transmitter.

 A3 supports a wide working voltage from 5 to 7.4V, you can use HV receiver or servo directly.

 The radio control models are not toys. The propellers rotate at high speed and pose potential risk, please carry

out debugging and flying in open space far away from the crowd. The beginner should be directed by someone

experienced.

About D/R and EXPO

When the gyro is activated, you might see that the range of movement of the servo become much larger than

before when moving the sticks. This is normal but not a problem because a rotation rate set point has been

applied to the outputs by the gyro. The sticks are not only used to control the movement of the surface, but

also the rotation rate of the plane in that axis. Anyway the controller will not change the settings of dual rate or

expo in your transmitter. The settings will always work in any flight mode.

Installation

The controller must be firmly mounted on the platform of the airframe by using the provided double-sided tape, as

close to the CG as possible. The controller can be attached flat or upright. However, the servo connector pins must

always point toward the rear of the plane (the shorter side with the setting button must always point toward the
heading direction). There’re 4 mounting orientations supported, as shown below.

Connection

Standard Receiver If a standard receiver is being used, you just need to connect the corresponding channels to

the pins AIL, ELE, RUD, MOD and GAIN using the included receiver wires. The aileron, elevator and rudder should be

always connected or it could not work. The MOD is used for flight mode control, if you don’t connect it the flight mode

will be set to normal as the default. The GAIN is used to adjust the master gain remotely. If you don’t connect it the

gain will be set to 100% all the time as the default. Wiring is as shown in the figure below.

Futaba S.Bus The Futaba’s S.Bus/S.Bus 2 is also

supported by A3. Because the S.Bus is a single-line

solution all channels are transmitted via one single line

you need to establish the first 6 channels in the correct

order in your transmitter before use. Here we use a

R7008SB receiver as an example because it supports

both S.Bus and S.Bus 2. You need to change the mode

for the R7008SB before using its S.Bus outputs, please

refer to the manual of it.
