Hey I know people ask this question why are my motors running away! But seriously that’s my problem I got props on them in the field as soon as it arms it takes off and failsafes as “runaway”.
So maybe I can turn this failsafes off? Idk it takes off fast straight up if the battery is balanced so I tried to get ready drop pitch as soon as I hit arm okay so now it’s like a rocket in the direction I’m pushing maybe not the best idea I calibrated this guy I had the axis all messed up but I fixed them so in the setup it’s rolling yawing and pitching correct I put some blue jay on there is resting idle too high?
I followed the Oscar guild I’m on the Goku versatile f405pro stack 4-1 ecu not sure if that’s the problem I was doing coustomer support forever you know there FC is not compatible with latest BF? When I flashed that said there was no gyro so then took the firmware before that and Frsky fyi only works with Verizon pre 2.X that was super angling to learn
Even if it’s possible, you do not want to turn off the failsafe for runaway. Your quad should do absolutely nothing when you arm it besides spinning the motors slowly. The default is like 4% throttle or so. If your quad is running away something is wrong. Motor order, prop direction, orientation, something. Take some time to check everything on the bench WITHOUT props on, and ensure it’s correct.
I also have no idea what you mean about the firmware, even if it’s not supported in 4.4, you should have versions newer than betaflight 2.X that work. That is ancient firmware. Frsky support has not gone anywhere either so maybe clarify that statement on here. There’s a bunch of people on here who will get you in the air without issues though
well it kinda worked got one flight where it armed and did not fly but still throttle then it went back to the same problem, and this is really weird since I did not change anything on the chopper, but it just gets weird and starts over powering its self its super weird
You need as previous post to provide a lot more info.
For a start, you have not in your post made it clear if this is an unflown new model, one previously flown OK, etc. What changed as this started? Firmware change?
Its not clear from your post if the runaway actually causes it to fly up vertically, tumble violently, or what?
It "could" be many things, including.............
Props right as a full set? Betaflight direction right (props in or out rotation)? ESC (BLHeli, etc) rotation direction right?
Lets be CLEAR on Hardware and firmware versions first.
In response to what your saying I think it might be the week frame its pretty bendy and the way I have the FC mounted the centre screws don't keep the arms solid even worse I think the original builder tried to soft mount the arms!? the original build was from someone else, I flew it for like 6seconds I think it had the same problem then the flight momba ECU failed I replaced it all with Goku versatile flywoo f405pro stack 4-1ECU
here are some videos of the problem after the first crash the fiberglass wings where super bendy kinda bent them back.

Yeah, I’d definitely suggest a new frame.
You shouldn’t be able to “bend the arms back”, and if you can, it’s very likely what’s introducing the vibration/oscillation that’s causing it to freak out.
Also, arming it while holding it down will cause it to exhibit the same out of control throttle that will happen with props off- but I did see the other video where you arm it without holding it down and it still takes off on its own.
Dangerous operations.
Disclaimer: I don’t know wtf I’m talking about. I wish I could get the smell of burnt electronics out of my nose.
a frame which isnt stiff can cause runaways, as i know it, it happens after launching, it looks like it does it whithout any input.
i like to see a fancy arm-softmounting xD would be nice if you can share a picture. a stiff frame is needed anyway to get good flight performance. maybe an inexpensive tbs source one?
as bad raven named above, did you double check the following: -board orientation -motormapping -motor direction -prop direction
additionaly you can chack for any short between frame and electronics, check all motorcrews for contact to the motorwindings.
i would suggest to do your research with props off in acromode, airmode feature off. these motors has some torq, acromode will give the same results but without risk to you and less risk to the electronics either. it realy doesnt make sense, its an esc-killer if the fc starts to give commands against the position it iw forced to be by feet or else.

I see some spacers (why???) between the arm and the carbon. Arms dangle and vibrate. The flight controller is going crazy. Look at the black box data, the flight controller alternately gives full throttle to different motors, and flies high into the sky. How did you secure the flight controller? Are the long screws tightened with a nut? Are the long screws loose?
the arms now have a bow from numerous times of arming it and dropping it at different hights but tried to bend it out flat eliminated all the tape bolted down the arms on the 8 connection points.
ill put the black box data on not sure how to read it yet but maybe interesting for someone..
PS no idea how to share BB info but here is a link that will last a week
Well, feel for you experiencing such issues, but it has to be said........
Never EVER buy a quad secondhand unless :-
1. You have seen it fly and fly well with your own eyes, not video
or
2. You are going to dismantle it for parts and accept that some bits may be beyond further use.
The frame is so badly assembled its going to be unusable as is, would require a total strip down. I'd say you will find repaired damage or even non-repaired damage under the black taped arms. Going further with Black Box, etc is a complete waste when such major visual issues abound.
At LEAST a new frame is likely required, BUT how did that frame get like is the big question/worry, as as apart from your tries and crashes, looks to me like previous person had issues (or created them trying to fly!), then likely bodged it up for sale. In that case I'd strongly suspect the FC board is possibly no longer for this world, either. Frames are pretty strong. Takes skill to trash one!
Frame was built by someone with no idea of the requirements, so suspect ALL, check and repair ALL, and you may come out OK.
At the minimum that quad needs complete strip down of the frame. You should be able to get the electronics off without de-soldering.
Strip it completely out, and ONLY re-use the frame if there are no repaired arm breaks and you can assemble it to be rigid and in-line.
The flight controller should be resiliant mounted on "gummies" rubber. We cannot see that from your single picture. Suggest you send us a photo asap of the electronics close enough and sharp enough to see solder connections and how its mounted in the frame from the top side, maybe with the top plate removed.
Anyway, I repeat, further electronic checks like BBox are NOT what this needs!
