I used the procedure as on the manual.
1.transmitter on 2.hold down the set button(next to switch)3.turn esc on while holding down button until the led flashes.
When i do that, it flashes plus beeps as described. Throttle on neutral already and i should press the set button again, but nothing happens, red leds still flashing and beeping. Only way to stop it beeping is to turn it off
I used Carson reflex pro, etroniks pulse EX3 pro, Futaba 3PL
