3.6.2 Remote Control Relay
The "remote-control relay" function is developed for ultra-long-distance flight
missions. It supports two ground units to relay control the same air unit to reach a
maximum transmission distance twice that of a single standard transmission system.
It can be widely used in cruise line inspection, unmanned distribution, unmanned
logistics and other fields.
Steps
1. Prepare two ground units (dual and repeater edition).
2. Go to “Multiple Links – Function Type”, assign the two ground units as “RC Relay
TX-A” and “RC Relay TX-B”.
3. Bind “TX-A” and “TX-B” to the same air unit in turns.
4. In “Control Switch” page, assign a switch / a button / a dial for switching control
to the air unit between “TX-A” to “TX-B”.
