ReadyToSky A3 V2 Airplane Gyro Flight Controller

The ReadyToSky A3 V2 is a gyro stabiliser for RC aeroplanes. It sits between the receiver and the servos and uses its gyro and accelerometer to steady the model, which makes it well suited to pilots learning on a trainer or flying wing.

Key features

• Four flight modes: Normal, Auto-balance, Auto-hover and Gyro Off
• One-click auto-hover holds the aeroplane nose-up in a vertical hover
• Mixing for standard, delta-wing (flying-wing) and V-tail airframes
• Servo frame rate selectable at 50, 125 or 250 Hz
• Separate gain adjustment for each flight mode, plus automatic stick centring
• Takes Futaba S.Bus / S.Bus2 input and runs on HV (7.4 V) receiver power

Power it from the receiver or ESC BEC rail within 5 to 7.4 V. Use the 50 Hz servo setting with analog servos and keep 125 or 250 Hz for digital servos that support those rates.
