Note
If it’s the transmitter from other brands used with RadioLink F121 Pro, make sure that the receiver should
be SBUS signal output supported. Once the receiver is installed on the mini drone, the phase of the throttle
should be reversed while the other three channels normal and the CH5 should be set with a 3-way switch to
change the flight mode and the CH7 set a switch (a 2-way switch or a 3-way switch is OK) for arm or disarm.
Servo phases of transmitters from other brands should be set according to the actual situation.
