Above are example connections, which require two transmitters and two receivers. One transmitter and receiver are used
for gimbal control and the other are used for aircraft control. Users can also use a transmitter and a receiver to control
both the gimbal and aircraft.
Configure the Aileron, Elevator, Rudder channels on the transmitter for gimbal control. Command stick stands for the
gimbal rotation velocity
，
the center position is for 0 and the endpoint for maximum velocity (both clockwise and counter
clockwise directions). (End Point is 100%)
Choose one 3-position switch/channel as the Z15 working modes switch.(MODE)
Choose one 2- position switch/channel as the camera shutter control switch(SHUT), one for the camera lens orientation
switch in Reset Mode (AUX2).
Please refer to the A2/ WKM/ACE ONE/ACE Waypoint User Manual for aircraft control setting.
Connect the receiver to GCU correctly.
Battery
Make sure the battery voltage is in the required range of both the aircraft and the gimbal if you use only one battery for
power supply.
