A3-V2 3-axis gyroscope remote control fixed-wing aircraft flight stability controller Features: Multiple modes, multiple functions,to make the flight more easily and freely. 1.Normal stabilization mode 2.Auto-balance mode(one key to save the aircraft, no matter what state the aircraft is in, one key to level the aircraft automatically) 3.Automatic crane mode(real one key crane,no matter what state the aircraft is in,one key aircraft automatically upright) 4.Gyroscope off mode Specifications: Input Voltage:DC 5V-7.4V, powered from the receiver directly Gyroscope:±2000 dps,1kHz Servo Frequency:50Hz/125Hz/250Hz Servo Travel:1520±500µs Limit 970-2070µs Operating Temperature:-40℃ to 85℃ Size:43mm*27mm Weight:12g(excluding wires) Package includes: 1*A3-V2 Flight Stabilizer Note: Before powering on the flight control. Please put the aileron,elevator and direction Rocker in the middle position first.After power on the flight control needs to be Gyroscope calibration and rocker center calibration.The blue light will Flash rapidly for About 3 seconds.Keep the aircraft stationary and do not move the stick during this Time.Until calibration is complete! Make sure to check the correct gyroscope correction direction for each channel Before flight,otherwise you may lose control of the aircraft or risk a crash! Change of receiver type requires re-powering the new settings to take effect. When using delta wing or V-tail mixed control.Please disable the relevant mixed Control on the remote control, which is already built into the A3. The new A3 series has an operating voltage of 5-7.4V. You can directly use the HV High-voltage version of the receiver or servo.
