Failsafe settings

[Joe Garfield]

I'm grateful for this thread. I've never set failsafe before because I couldn't decide what was the "right way." But obviously making sure throttle is limited or cut is, well, obvious. My current plane is a glider so throttle off is fine. For something like my contest F3A plane, throttle to idle seems to make sense as someone said above, hopefully its making enough noise and slowing down to warn someone, but at the same time sustaining flight a little longer to hopefully regain control. Guys in my old club used set failsafe to full down elevator to intentionally ditch the plane and try not to hurt people. I guess if you have dihedral you can set ailerons neutral and the plane might right itself. But you never know what the plane will be doing when it happens, so I'm going to stick with limiting throttle and probably nothing else.

I'm voting 'custom' as I'm setting up new radios and a new plane anyway, so will set to throttle off for gliders, and throttle to idle for power planes.

I'm going with custom. With all the sensors available nowadays, GPS, etc it might be possible to have the model come back towards point of take off to try to regain signal???
Depends on the model and sensors, but the recievers, with stabilization gyros, GPS, etc..it's almost within the realm of possibility.

Drones do it on command....why not a plane?

Per the FAA our planes are drones!

I got something for the FAA...

Remember they have a bigger stick!

Yes, there are some options out there that will drive your plane back to the point of origin if all signal is lost. You need to set your failsafe for No Packets to trigger the return to home feature.

I have better range lol

I was the president of our club for the past two years and I harped on failsafe many times, but alas, it's really about herding cats. One member was doing a setup on the bench, with another member holding the airplane for him. He sort of finished and shut off the transmitter, at which point the motor went full and lurched forward. Though someone was holding it, he wasn't gripping it that tight at the time and it caught him off guard. The guy with the radio ended up with a couple minor cuts.
Another member crashed in an off-limits area, and of course, I got texts and phone calls, as I am the person that is allowed to talk to the land owner. I got to the field an hour later, and was immediately descended upon by a couple people. Well, as it turns out, this member, who regularly attends our meetings and has positively heard me harp on failsafe, wasn't sure if his plane had it setup. So, basically he had been sitting there for that hour with his transmitter on as he didn't want a poorly setup throttle to cause a fire.
I have brought up the possibility of requiring "proof of failsafe" for all aircraft.

good morning all...i run frsky x12s transmitter on accst. i have no problem setting failsafe normally. recently i got an rb25 for a lager aircraft.
setup a RX8R and xm on sbus with redundant with all surfaces having their own servo. everything works as it should, except the failsafe. if i setup the failsafe on the transmitter through the rb25 , no matter which failsafe i select, it does the same thing. all surfaces slam opposite to each other. i then tried rebinding the recievers seperate from the rb25 and setting failsafe on transmitter then plugging into rb25. it still does exaactly the same thing. i thought maybe a faulty rb25, so i swapped it with a spare. same result. what am i doing wrong?

The RB25 has its own failsafe setup, have you setup that?

that setup guide is for ethos and im using opentx. is there a way to setup with opentx?
is there a lua script for it ?

 

[gnichola]

Oh, I missed that part, and I am not sure. I did a quick search and couldn't find anything, but I would assume there is a lua script for it.
