Hi. I’m using a Matek F405 Wing for my Nano Talon FPV plane with the last iNAV firmware.

Now the Problem:

I’m testing the RTH function in my stand and sometimes when I active the RTH function the throttle goes to 0% and sometimes it works fine, going to 100%. Why sometimes the throttle don’t work and sometimes it’s works. Is This because the minimum distance for RTH configuration? Because when i put the minimum distance for RTH in “0”, the problem is the same.
Someone can help me?

Try asking in the fixed wing section of the forum, I suspect not many of us have much experience with features like that. Maybe it has something to do with your altitude?

You saying that sometimes going into RTH wing just shuts off... or idles at speed? Does it turn around? Maybe has something to do with the GPS... but again I really don't know.. for all I know it doesn't even have GPS...

Your best bet would be to try asking in the fixed wing section of this forum
