A few years ago Lee I lost my Dart250g, on its maiden! I actually watched it fly away in a straight line until it went out of sight. Guess who hadn't tested the failsafe. Got it back a couple of weeks later after a friend found it by shear luck walking his dog. Thankfully my contact details were on it. Never lost a model since!!!!!! I sulked for days, at the age of 50😂.
A fantastic refresher, especially for people like me who used to use Spektrum but now have a combination of Spectrum, CRSF and FrSky receivers on both fixed wing and quads. It's easy to muddle stuff up. I'm gonna look through all my Companion settings now to see if I have one wrong!
This reminds me there are planes I have flown several times where I honestly do not know the specifics of the failsafe conditions/parameters or functionality. Yep, I know I should know, but this video has reminded me I really don't know in some cases. Really need to fix this lapse in knowledge and responsibility. I will note, however, that fly-aways can happen due to mechanical failure even if you have return to home set up on failsafe and a flight controller that you've tested hundreds of times. I had a plane that had I think a servo strip out on me, or some other control issue, and the plane blew away in the wind, despite many attempts to bring it back manually and via RTL, because the flight controller could not turn the plane without rolling over upside down. I lost that plane in the lake. I'll never see it again.
Great advice even when it comes to unwanted RTHs. I used to set my receivers to output “RTH activated” on signal loss. But that setup would flip my planes out of waypoint mode as soon as someone walked or parked in front of my radio, ruining the mission in progress. Now that I use “no pulses”, the signal loss reaction is not up to the receiver, but to the FC, which can be set to be a bit more phlegmatic about momentary signal loss during missions and stick to the route for a few seconds while I get things sorted.
Thank you for this info, I’ve looked but couldn’t find any good descriptions of failsafe in frsky literature. One question in a non FC model what does “receiver” do in failsafe?
Before I go fly my FPV FC planes I ask myself two questions - 1. Do I feel like a very long walk, 2. Can I emotionally cope today if my plane is lost. If I answer no to either I'm not in the mood to deal with it!. I haven't lost a FC plane yet fingers crossed.
Thank you! I’m building a 7” quad, when BF RTH him activated from either failsafe or switch how do you regain control is it just start inputting and you take over or is there a “thing/sequence” to regain control please? Looked for videos but never found a good one on regaining with a stickcam, thanks again
Depends how it was activated. If via a mode switch, switch to another mode to change. If via a Failsafe, if the radio reconnects then it'll back toy he mode it was in before it lost connection. Failsafe is only to get the model back into control range, or if the radio isnt working, bring it home... Happy flying
That is helpful. But now I am wondering what the FC does when it is RTHing and suddenly gets back in radio range. Does failsafe cancel and now you have to be ready to fly it again?
Once a valid signal is seen again by the flight controller, by default it'll cancel the failsage operation and go into the mode selected by the valid mode channel setting. Failsafe is there to get the model closer to you so you can reconnect, or land in the case that reconnection isn't possible... Best of luck
@@Painless360 The ArduPlane docs say: The action set by FS_LONG_ACTN will continue even if your RC signal is reacquired, if the flight mode is the same as it was before the failsafe action began. Once RC signal is reacquired, the FS_LONG_ACTN can be exited via a mode change on the FLTMODE_CH. If the mode on the RC transmitter was changed during the failsafe period, then this changed mode is entered after the RC signal is restored
What do i set on my CRossfire failsafe? Running opentx 2.3.11 and a crossfire micro module? The module only sets channel position and the nano rx only has F.pos and Cut… there is no option for No Pulses

Thanks a bunch for all the tips, Lee! Really valuable information! 😃
Stay safe there with your family! 🖖😊

Easy for full size crsf with the screen... set switches and hit the button. Rth is key here.

Nice info, I always have a flyaway phobia when fly without FC
Thanks for the advice, really helpful.
Thank you for this info, I’ve looked but couldn’t find any good descriptions of failsafe in frsky literature. One question in a non FC model what does “receiver” do in failsafe?
Allowed you to store the Failsafe channel positions on the RX by pressing he bind button briefly. Happy flying
Before I go fly my FPV FC planes I ask myself two questions -
1. Do I feel like a very long walk,
2. Can I emotionally cope today if my plane is lost.

Are all (or most) receivers capable of failsafe? I have a Jumper T16 with Edge TX and use either a Jumper RX or Flysky RX
And now a live demo ofcourse 😋
That, I leave up to you.. Best of luck

Cut = no pulses
@@Painless360 thank you for your most gracious reply sir!! A big fan of your channel!! Kudos to you!!!
👍
A tether helps lol
Love no pulses
