Usage
The landing gear can be used by following the steps below after assembly & connection.
1. Make sure the transmitter & receiver batteries are fully charged.
2. Toggle the switch to the [Lower] position, and then turn on the transmitter.
3. Make sure the [R], [L] and [IN] connections are correct and firmly connected.
4. Make sure the Landing Gear is at the [Lower] position, and then power on the system. If the green LED is on
solid, then this is a normal start. If the LED will flash GREEN slowly, please re-calibrate the system according
to the procedure of Travel Calibration.
5. Make sure to toggle the switch to the [Retracted] position only AFTER you takeoff the aircraft.
6. When the aircraft is landing, please toggle the switch to the [Lower] position for a safe landing.
Tips
 The system will turn off the servo power temporarily within 3 seconds after the landing gear has reached the
target position.
 When powering on the system, if the TX switch is in the [Retracted] position, which is the unsafe signal for
the landing gear, the LED will quickly flash RED. Please toggle the switch to the [Lower] position.
 If there is an abnormal signal or no signal input into the [IN] port the LED will slowly flash RED. Please check
the receiver and the connections.
 If the power consumption of the servos is too large when in use, the LED will be on solid RED. If this status
lasts more than 4 seconds, the landing gear will lower and the LED will flash GREEN slowly. Please
re-calibrate the system.
