Gyroscope Reset

If the following conditions occur, the FY-41AP initialization is recommended:

1. The device has not been used for a long time.

2. There is a change in environmental temperature of over 30 degrees since last flight.

3. The Red LED flashes continuously even when the FY-41AP remains stationary and

you never activate the motor.

Note:

For a better flight, we suggest you reset the gyro before each flight.

There are two ways to realize the gyro reset. (The FY-41AP must be kept stationary

during the gyro reset procedure)

1. Through SW1:

On SW1, switch stabilized mode to fixed altitude mode 6 times, each time interval has to be

less than 3 seconds as follows:

stabilized mode→fixed altitude mode →stabilized mode →fixed altitude mode →stabilized

mode→fixed altitude mode →stabilized mode →fixed altitude mode →stabilized mode

→fixed altitude mode →stabilized mode →fixed altitude mode.

2. Through FY-41AP setting software ―Init GYRO‖ button.

Calibrate the Compass

FY-41AP has a built-in magnetic field sensor which can measure the earth‘s orientation

position, providing the basis of the hover function. If the magnetic field is disturbed, the

hovering mode will draw a circle motion and be unable to hover.

FY-41AP internal procedure will correct magnetic field in real time, since the magnetic

field will change if the motor starts, so the best way is that control aircraft spin over three

circles after take-off. The internal procedure will calibrate the magnetic field automatically.

This is very critical, and can affect the hover mode directly.

Attention: If you want to save the compass calibration value permanently, please

take off and wait the aircraft automatic into the state before execute Combination Stick

Commands (CSC) and do the gyro reset. The compass calibration value will be saved

into FY-41AP through the gyro reset procedure.
