Futaba receiver link with 3 Drone and 3 receiver

I linked three receivers each. ( when I linking I trun off other receivers )

but I turn on my transmitter than I can watch 3 green LED of receivers

so armed 3 Drones at the same time when I use transmitter for arming

I did change system select but armed 3 drones

checked ID 1 receiver : p2056513**, 2 receiver : p2056501**, 3 receiver p2056513** and saved name each

sad :frowning:

I want to use 1 transmitter and 3 drones and I pick first drone for control

transmitter ( futaba 14sg ) Mode 2 Mode D
receiver ( R7008SB )
