4 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
solid on, then this is a normal start. If the LED flashes 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.
Retracted ：Toggle the switch to
this position to retract the
landing gear (Fig.1)
Lower ：Toggle the switch to this
position to lower the landing
gear (Fig. 2)
Tips:
(1) If the switch of Transmitter has FailSafe function,
set the FailSafe value to the [Lower] position, so
that the landing gear will be in [Lower] status when
the receiver enters FailSafe mode, to land the
aircraft safely.
(2) To avoid false switch triggering, you can use the
slide lever or other trim as the landing gear’s
control switch.
