Large Model Association Forum

I am trying to set up a twin petrol model using twin recievers. I have got both throttles to work independently on the throttle stick and now the problem
Channel 3 and 8 are being used.
When I try to set the failsafe on 3 no problem failsafe will not set on auxillary 8.
The same problem occurs when trying to set the throttle cut yet again only 3 will cut on switch designated
Radio is a zap 9 old i know but should still do the job

John.
Why dont you have both throttle servks on channel 3. Should both work then

I assume your 9z is on futaba FASST? You could try a FASST FrSky Rx . The faile safe is on all channels.
