Futaba FDLS-1 Dual RX Link System

The Futaba FDLS-1 is a receiver security system for your model (RC helicopter or RC airplane).
It is indeed capable of switching the secondary receiver signal in a blink of an eye if the primary receiver fails for any reason.
Of course, it is therefore necessary to have two Futaba S-Bus2 / S-Bus receivers in the model.
Link the two receivers using the dual receiver feature of the transmitter. For systems without dual receiver capability, link each receiver in turn.

Warning: do not connect servos, S.Bus2 sensors or the battery directly to the receiver. A large current could flow in the FDLS-1 and cause a malfunction. Do not supply receiver power from the ESC (See wiring diagram).
