Note: When using a non-RadioLink transmitter, if the attitude calibration is unsuccessful when pushing the left stick (left and
down) and the right stick (right and down), please change th e direction of the channel in the transmitter. M ake sure when
pushing the joystick as above, th e value range of channel 1 to channel 4 is:
CH1 2000 µ s, CH2 20 00 µs, CH3 1 000 µs, CH4 1000 µs
Take an open source transmitter as example. Th e ser vo d isplay of channel 1 to channel 4 when calibrating the attitude
successfully is as shown below:
CH1 2000 µ s (opentx +100), CH 2 2 000 µs (opentx +100)
CH3 1000 µ s (opentx -100), CH4 1000 µs (opentx -100)
