Title: Fail safe
Post by: Pragmatist on July 02, 2019, 09:54:32 am

is this essential in R/C boats as I’ve just learned my Taranis X9D plus doesn’t support fail safe on the L9R receiver?

Not for electric-powered models, because most electronic speed controllers will cut the motor if a valid signal is lost. I/C models are a totally different matter; every different radio manufacturer seems to have a different way of setting up the position of the servos in failsafe mode. It used to be possible to buy 'stand-alone' failsafe units but I'm not sure if or where there are any still available other than those designed specifically for petrol engines.

I am sure you can do it on the radio, I have just googled it and got a few links this is the one that might help https://www.youtube.com/watch?v=NtBA9I2h_yA&list=RD2W6xU50zK04&index=6

Pretty sure on the Taranis you set the transmitter to "no pulses" setting. That should kill the receiver if signal lost

Instruction on right https://cdn.getfpv.com/media/wysiwyg/documentation/Frsky-L9R-Manual.pdf (https://cdn.getfpv.com/media/wysiwyg/documentation/Frsky-L9R-Manual.pdf)


I see it states exception for X9D. but I think that is for preset failsafe positions.


No pulses should stop everything which would be no good for aircraft but fine for boats
