Hobby Eagle New A3 Flight Controller for RC Plane

Hobby Eagle A3 Flight Controller for RC Plane

A3 Supports 4 flight modes, including Normal, Auto-balance , Auto-hover and Gyro Off mode. You can switch them using a 3-way switch on the transmitter. But if you are using a 2-way switch instead then you can only use 2 of them during flight. The color of the LED shows you that the flight mode currently selected, as shown below.

    One-click Hover, Self-hover.
    4 Flight Modes: Normal, Auto-balance, Auto-hover, Gyro Off.
    Standard wing type, Delta-wing and V-tail.
    Remote Master Gain.
    Servo Frequencies: 50Hz/125Hz/250Hz；
    Separated gain adjustment for each flight mode.
    Automatic stick centering.
    HV (7.4) operating voltage supported.
    Futaba S.Bus / S.Bus 2 supported.
    Easy to use, extremely well-suited to beginners.

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.

Flight Mode

A3 Supports 4 flight modes, including Normal, Auto-balance , Auto-hover and Gyro Off mode. You can switch them using a 3-way switch on the transmitter. But if you are using a 2-way switch instead then you can only use 2 of them during flight. The color of the LED shows you that the flight mode currently selected, as shown below.

Normal Mode

Normal mode is the most basic application of the gyro. In this mode, the gyro will sense angular velocity on each axis and make a momentary reaction. The normal mode is suitable for all types of fixed-wings, it can effectively improve the stability of your plane specially on a windy day.
Auto-balance Mode

The auto-balance mode is designed for the new beginners or the FPV applications. When operating in this mode, the controller will command the plane to maintain level flight automatically when you release the sticks. When switch it to this mode from any other modes in an emergency, the plane will recover to the level flight automatically, which we call "one-click rescue".
 

Auto-hover Mode

The auto-hover mode is another form of the self balance ability of the controller. The only difference is that the correction from the gyro will be applied to both pitch and yaw axes, to keep the plane always vertical. When switch to this mode, the plane will lift its nose and start to hover automatically, which we call "one-click hover".
 

Gyro Off Mode

Choose this mode to disable the gyros for all channels. The plane will be completely under the control of the radio. The plane will go back to its previous performance when operating it in this mode. Usually it is only used to test.

One-click Hover and Auto-hover

A new flight mode which we call Auto-hover was added in new A3. When operating in this mode, the self-balance ability will be applied to both elevator and rudder. The plane can hold its hover attitude without any control except the throttle.

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.
