Hello Richard .
I am having serious issues setting up fail safe on the throttle channel on the Futaba T18SZ and R7008SB receivers through the power box expander unit .
The receivers can be programmed to fail safe on all channels if connected separately or collectively to a power box sensor switch but when these receivers are connected and operated through the Power Box expander , I am not able to program any of the fail safe channels on the transmitter , particularly the throttle channels which is essential to me
I have six of these expander units on my jets and they operate satisfactorily with Jeti /JR and Futaba radio , but as it has become compulsory for us to set up failsafe on the throttle channel on our club , I have not been able to do this .
Could you help please
