FAQ about D/R and EXPO Settings: 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, expo or end point in your transmitter. The settings will always work in any flight mode.

The new A3 series provides 5-channel inputs and 3-channel outputs. You only need to connect the receiver and servos to the corresponding pins on the side of the controller. The knobs are used to adjust the gain for each flight mode, clockwise for increase, anticlockwise for decrease. Futaba's S.Bus and S.Bus 2 are supported by new A3 series now.

Caution Notes

  • Please confirm the 13-bit unique product series number (S/N) on the bar code label when purchasing. This number can be verified at our website and it is also required in the after-sale service, please keep it securely!
  • 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, just 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.
  • The new A3 series 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.
