Item Name:
Eagle A3-L V2 3-Axis Gyro RC Fixed-Wing Airplane Flight Stabilization Controller

The Eagle A3-L Airplane gyro is the new upgraded version of the top selling Eagle Pro SE. This new version has been completely redesigned and is a significant upgrade over the previous generation A3 Pro. 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. While the A3-L provides excellent stability for larger planes and jets, it is also perfect for smaller airplanes or where space is a premium. The Eagle A3-L offers an incredible advance in airplane gyro technology for an affordable price.


  • Works with all major receiver brands including Spektrum, Futaba, Hitec, JR, Tactic, and more. 
  • 3 Pre-programmed flight modes (flight modes are selected using a 3 position switch on your transmitter)
    (1) Normal Mode (2D Mode): this is the standard flight stabilization mode found on most airplane gyros.
    (2) 3D Flight Mode: this mode will attempt to hold the LAST position the aicraft 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 as long as the pilot provides appropriate throttle input.
    (3) Gyro Deactivated Mode: this turns the gyro off to allow unassisted/non-stablized flight. 
  • 3 Wing Types: Normal Airplane, Flying-wing (Delta-wing) and V-tail. 
  • One-key setting mode with colored LED indicator light 
  • Remote Master Gain
