IMPORTANT - Please Read This Carefully

• Proper setup of the HobbyEagle Gyro is crucial. Read the gyro instruction manual completely before attempting to fly your aircraft. Failure to follow setup instructions can result in loss of control and inevitable damage to your aircraft.
• Ensure the gyro is installed in the proper orientation (see manual) and is mounted to a hard surface near the aircraft's CG point.
• When you first plug in your aircraft battery DO NOT move your aircraft for at least 10 seconds to allow the gyro to perform self-calibration.
• It is crucial to verify that the gyro is moving the control surfaces in the correct direction BEFORE attempting to fly your aircraft. Failure to do so could result in loss of control during flight.
• Setup one of your gyro control switches (3 position switch on your radio) to activate Gyro Disable. This safety feature will allow you turn off the gyro if you encounter any issues during flight.
• ANY warranty claim for HobbyEagle gyros applies to the gyro only, not the aircraft in which the gyro was installed.

Wiring

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 to increase, anti-clockwise to decrease. Futaba's S.Bus and S.Bus 2 are supported by the new A3 series.

Standard PWM Receiver Connection

• [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

Single-line Receiver Connection

A3 Lite supports PPM and Futaba S.Bus serial receivers which allows you to connect the gyro to the receiver with one single wire. When using a specific type of these receivers the appropriate type of receiver channel allocation will be preset in the A3 Lite. Please refer to the table below and check if your radio transmits the channels in the correct order. If you use a standard PWM receiver with standard wiring layout the channel mapping does not apply. When A3 Lite is operating in single line receiver mode, the [THR Out/AIL] can be used as the throttle output channel for the ESC or the throttle servo if a mini receiver is being used which has no additional output connectors.

Please note that the Remote Master Gain is disabled in single line mode as default. Choose a channel number for gain channel in item 8 of the Setup Menu to activate this feature if needed.

Setup Menu

To get into the Setup Menu, press and hold the button for about 2 seconds until the LED starts flashing Blue and Red quickly. The Setup Menu contains 8 setting functions which normally only need to be setup once after installation.

Function Selection
In the Setup Menu, the LED will flash Blue and Red several times every 3 seconds in a loop and the number of times LED flashes shows at which function item you are currently. For example, one Blue and Red flashing means the first setting "Aileron Gyro Direction", after waiting about 3 seconds, a twice Blue and Red flashing means the second setting "Elevator Gyro Direction", etc.

Option Switching
When you reach the function that you wish to operate in, short press the button to get into it. After entering in, the current selected option is indicated by the color of the LED. Each short press of the button advances the option to the next value. After you finish making your selection, just wait for 5 seconds until the LED starts blink quickly which indicates that the modified is saved and then you will be brought back to the Setup Menu level automatically. If you do not want to change anything, just wait for timeout without any operation.

Exit of Menu
To exit the menu just keep the button pressed for 2 seconds again until the LED starts flashing Blue and Red quickly.
