Servo power will shut off 3 seconds after the landing gear has reached its target position.
When powering on the system, if the transmitter switch is in the [Upper] position, the LED will ash
red quickly as a warning. Toggle the switch to the [Lower] position to continue.
If there is an abnormal signal or no signal input into the [IN] port, the LED will slowly ash red.
Check receiver and connections for problems.
If servo power consumption is too high, the LED will light up red. If this lasts more than 4 seconds,
the landing gear will lower and the LED will ash green slowly. Re-calibration is needed before
ying.
A2 flight control system users can use the A2 Assistant Software to set intelligent gear on the
“Advanced” page. Refer to the “A2 user manual” for details.
