Eagle A3-L V2 Airplane Flight Stabilizer / 3 Axis Gyro - HEA3LITE

The Eagle A3-L airplane gyro is the new upgraded version of the top selling Eagle Pro SE. Major updates include a new light-weight protective shell, updated v2.7 logic software, remote master gain control, and automatic gyro calibration at start-up. The Eagle A3-L has three gyro modes: normal/2D mode, 3D mode, and gyro deactivated mode. Additionally it supports both analog and digital servos and provides separate gain adjustments for each flight mode. All functions of the Eagle A3-L are easy to setup via a simple on-board button and indicator LED. The A3-L provides excellent stability for any size electric RC plane, offering an incredible advance in airplane gyro technology for an affordable price.

Why use an airplane gyro? - Gyros (also called flight stabilizers) help keep your airplane stable during take-off, flight maneuvers, and landings which can be helpful during windy days or when learning how to fly RC planes. Once thought to be for beginners only, Gyros are now common in all classes of aircraft and are utilized by all levels of flyers. Gyros are great for learning, they let pilots practice advanced aerobatics, they give you piece of mind in less than ideal flight conditions, and they can often help you avoid costly crash damage.

Note: Not for use with gas/nitro aircraft.

    • Normal Mode (2D Mode): this is the standard flight stabilization mode.
    • 3D Flight Mode: this mode will attempt to hold the LAST position the aircraft was in. For example, if you put the airplane into a knife edge and then activate 3D mode, the airplane will hold the knife edge.

IMPORTANT - Please Read This Carefully

  • Proper setup of the Hobby Eagle 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 Hobby Eagle 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.

A3-L Setting Menu

When the controller is working, press and hold down the button for more than 2 seconds which will allow you to enter the settings menu as all settings are completed by the button. Please consult the manual for more details.

Package Contents

The box contains 4 receiver wires and 2 pieces of double-sided tape in addition to the A3.

Product Updates:

  • March 5, 2018 - Important control logic change for Atti-Lock mode. In the new firmware, the attitude locking will take effect only when the sticks are in their center positions. When moving the sticks the gyro will switch to Normal mode automatically. 
  • March 1, 2018 - Dynamic basic gain drop added for all flight mode except for Trainer mode when moving the sticks. The drop rate of aileron, elevator and rudder can be set separately by changing the 'Response Gain'. The larger the Response Gain is, the faster the basic gain will reduce step by step and finally disappeared.
  • May 5, 2017 - This product is not recommended for Nitro or Gas-powered R/C aircraft.

Easy set up!

Motion rc did a great job of setup walk through. Haven't flown my jet yet ( Very windy). Picked OK on the performance and function only because I haven't flown the plane yet.

Eagle A3-L V2 3 Axis Airplane Gyro,

I have been using this gyro since the time it came out.Easy to install and works excellent on crosswind conditions and generally helps make the jet or plane fly the best it can. It can be turned off or on in flight also set up for more or less sensitivity while in flight. For twenty three dollars I highly recommend it.Thanks Motion rc for having affordable Gyro's that work great.

Works great, but without the video James did it would be difficult to figure out how it works with the instructions provided.

A3-L V2 3 Flight Stabalizer

Very good product. Easy to install and program. If you live in the USA price is good. Purchasing from Canada not so cheap after shipping and taxes. Still considering the other flight stabalizers I've purchased, this one is the best.

Eagle A3-L V2 3 Axis Airplane Gyro

Seems to work perfectly with a JR/Spectrum DSM2 TX - using a 2.4ghz module in an older JR8103 TX. Having trouble with the missing function - only have a 2 position switch - Full On or HOLD Position are the only functions - my problem with programming the older JR radio! Have not flown the model with the gyro function (or anything else at this point).
