Betaflight won't arm - all 26 reasons explained

Let's go through all 26 different reasons why Betaflight is not arming. They are all visible in the Betaflight Configurator and reported as arming disabled flags. Some of them are simple to get and easy to fix. Some are super rare and signal major problems. Let's do a speed run and through all of them!

solved all my problems 55 sec into the vid, nice.

Great video! There one more I can think of . Crash flip !! If the arm switch is the same as the flip over crash the quad won’t arm

[MCsCreations]

Fantastic, Pawel! Thanks a lot for the video! 😃
Stay safe there with your family! 🖖😊

[MrBcast]

And now, the fist 126 reasons why inav won't arm. nav_extra_extra_safety_arming = ON allowed values ON, very ON, EXTREME ON.

So what if upu have no arm disable warranty but it still will not arm? Endpoints setup, not gps rescue as you need gps lock before taking off, switch arming is on and working, throttle down don't work. Tx in binded with rx and is showing in bf, done is level and collaborated. Just refuses to spin motors with tx but in bf with sliders they spin

I could use some help with this one...I bought a used mob 6 on ebay, i got it to bind to my TS16X pretty easily. I flew two packs with it. Last flight battery died mid flight. When i powered it up again, the entire OSD was gone, like everything got wiped out. The start up beeps went from 5 beeps, to only 3. I fixed that issue though. Full pack and it just wouldn't arm anymore. Why would this happen?

I cleared ANGLE, CLI, MSP, LOAD, i have no arming flags, literally zero, but the drone will not arm.

Excellent roundup! I will send a lot of noobs to you from reddit ;-)

The one thing you forgot, was if a pilot does an incorrect CLI dump, and is actually able to save and execute the dump, then the quad will load up, show that you have telemetry, and even lose telemetry when you unplug the quad. But not arm.

And you notice in the modes tab, that when you go to arm, the little ChickLit moves into the slider range, but arm is not highlighted. Nor are some or all of the different things like air mode, horizon, crash flip, etc..

So the solution obviously is to find the correct CLI dump. It happened to me, I found this video, and then later was lucky enough to grab the correct CLI dump for a GEPRC phantom analog. Hit me up if you need it.

I love you, and here I did not even know it tells you ! I’m an such a noob …

[micsherwood]

I have Many qwads now that i have bound (BetaFPV TX module and HM EP2 RX's) and BF gives RXloss in cli tab, and still do not arm. what else could be holding ALL my qwads from arming? I only have one qwad, using ELRS that is bound, able to get into BF and running great. My other 8 get nowhere.

Lol first line, look at the effing info box, it was my newly installed gps, thanks! bardwell didnt say that on his vid.

[andershoel]
