Product Details

A3 Super 4 is a high-performance and functional 6-axis gyro and stabilizer designed for R/C airplanes. The hardware has been improved yet again based on the successful previous generation. Multi-protocol serial digital receiver support and customizable output channels added to make the gyro more user-friendly and reliable.

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. 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.

Important:  The A3 Super 4 is an advanced flight stabilizer. You must have a Windows PC, know how to install drivers, and have a working knowledge of Windows applications in order to program this gyro.

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.

Standard PWM Receiver Connection

When using a standard PWM receiver, A3 Super 4 has 7 input channels in which at least one channel should be connected to the receiver in Aileron (A), Elevator (E) and Rudder (R), or the gyro will enter the receiver timeout mode (Red Slow Flashing). [Serial RX/M] is used for flight mode switching, use a 3-position switch of the transmitter to switch the flight mode during flight. [G] is used for remote master gain control, a slide lever or a switch of the transmitter can be used to tune or change the master gain during flight. Connect the ESC or the throttle servo to the receiver directly without passing through the gyro.

Single-line Receiver Connection

A3 Super 4 supports PPM and multi-protocol digital serial receivers which allows you to connect the receiver to the gyro with one single wire on the slot [Serial RX/M]. When using single-line receivers, 2 auxiliary pass-through channels (AUX1 and AUX2) are available which can be used to output the expected channels of the receiver directly. By default, AUX1 is always assigned to Throttle and applies to OUT5, while AUX2 is disabled. Depending upon the receiver type selected, The gyro uses the preset channel assignment to recognize the channels from the receiver. Refer to the table below and check if your radio transmits the channels in the correct order. After each time you have changed the receiver type the current channel settings will be reset to the default. Choose "None" for those channels you do not use.

Customizable Output Channels

A3 Super 4 provides 5 customized PWM output channels, including OUT1 to OUT5, of which the function can be specified by user.
