I have run into a problem when trying to get failsafe to work with my Futaba T9CP 35mhz Tx and FP-R138DF Rx.
I have set the parameters correctly however, there is so much interference once I switch the Tx off that failsafe will not initialise. All of the channels fluctuate a lot including 3 (throttle used for failsafe) and 8 (used for flightmode selection). This has the effect of the APM switching between flight modes randomly - a fine recipe for a crash if I were to fly out of Tx range.
Can anyone suggest a fix for this or have I just chosen the wrong Tx/Rx for what I want to achieve? (My choice of 35mhz was made at an early stage because I read that range was a strongpoint AND I am in the UK so 2.4Ghz video Tx is my preference).
P.S. My Mavlink OSD stopped working tonight as well. Think I may have fried it as I never checked VCC was <5.25V... you live and learn!

No luck with your receiver,
If you want FailSafe with classic Futaba radio, you have to go to PCM receiver.
Thankyou Marc,
I purchased an R149 PCM rx and failsafe works perfectly now.
:)
Thanks for the feedback,
Marc
