HEA3PRO

Hobby Eagle A3 Pro Standard Edition 6-Axis Airplane Gyro - HEA3PRO

The new A3 Pro is a high-performance and functional 6-axis gyro and stabilizer designed for R/C airplanes. This gyro can be used with nearly any size and type of R/C airplanes and its primary function is to make flying as easy and as comfortable as possible for the pilot by using stabilization technology that keeps your model flying as it works to counter the effects of variable wind/weather by making slight adjustments to the control surfaces.

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. Gyros also help you master aerobatic maneuvers like knife edges and hovering as the system can "lock" in a planes position / trajectory. 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.

Note: Not for use with gas/nitro aircraft.

Features:

  • 32-bit MCU, High-Precision 6-axis MEMS sensor
  • Improved hardware platform and new firmware
  • 6 Pre-programmed flight modes:
    • Gyro Off Mode - When this mode is selected, the gyro will be deactivated completely.
    • Normal Mode (2D Mode) - This is the standard flight stabilization mode.
    • Atti-Lock Mode (3D Mode) - The gyro will attempt to hold your last position by making constant corrections to rotational movements on each axis. An example would be holding a knife edge maneuver.
    • Trainer Mode - In this mode you can only tilt the plane to a certain angle and rolls and loops are not allowed.
    • Auto-Level Mode - The plane will be brought to normal, level flight automatically when releasing the sticks.
    • Auto Hover Mode - Provides the same functionality as the Auto-Level mode, except when you release the sticks, the plane will be brought to the vertical position (nose up) and hold a hover.
  • 3 Wing Types: (Standard, Delta, and V-Tail)
  • Compatible with most standard, PPM single-line and Futaba's S.Bus and S.Bus 2 receivers
  • Separate gain adjustment for aileron, elevator and rudder
  • Remote master gain support
  • Sub trim and travel limit support

Includes:

  • Eagle A3 Pro 6-Axis airplane gyro
  • 16V EZ-Plug capacitor to help maintain a secure voltage level during flight

  • Five 150mm (6") male-to-male servo wires to connect the A3 Pro to your receiver

Specifications:

  • Main Controller: 32-bit MCU
  • Sensor: High-precision 3-axis gyroscope and 3-axis accelerometer
  • Gyroscope Scale Range: ±2000 dps

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.

A3 Pro Broken

My A3 Pro would only function properly in Normal Mode. Any other mode such as Trainer Mode would lock the ailerons into extreme up/down combination guaranteeing a crash.

Great value, easy to use

this is a great stability gyro for the price. Programming is easy. I recommend you watch one of the how to videos and print the light sequence chart for reference. Functions really well. The attitude hold works great. Normal stability functions are 4.0

A3-pro gyro

Once you understand the lighting system in setting up the gyro it is not too difficult to install only one flight so far but I am impressed with the performance

Works great Takes a while

Works great Takes a while to figure out the programing. After you have done several it's not too bad. Motion rc the best to work with.

Spektrum users BEWARE!!!

Great and reliable gyro. One major problem for non Futaba users. Poor instructions. No where is it mentioned that the default receiver instructions are for Futaba nomenclature users. This is poor manual writing and is inexcusable. Notice the defaults for the receiver do not reflect the channel assignments for a Specktrum receiver. You need to change the settings. If you do not the elevator and ailerons will be erratic and if you fly this way you are certain to crash. The rudder will function fine since the default is Channel 4 (same as Spektrum). MotionRC should say something about this in their item description.
