Drone violently oscillating when armed

[minor valley]

i think it does that cause theres no props, so it thinks it should be moving but it doesnt, so it spins the motors faster, and creates its own feedback loop

i dont think it should be that violent though

[wintry bluff]

Should I test it outside with props on?

The video that I posted was just arming it without adding any throttle

[minor valley]

if you do, stand back, and do it in a large open space

like, not your backyard

[minor valley]

yeah, but even at no throttle props will still generate a small amount of thrust, thats just how they work

[wintry bluff]

Do you have any ideas why it might be so violent?

[minor valley]

i dunno, might be the stand its on, might be the stack, might be betaflight settings

if you want to do another props off test, try a more stable stand

[twin latch]

plastic frame?

[minor valley]

that to

[wintry bluff]

its 3d printed, but rn its a unibody, so there are no screw connections

its a design that others have used so I don't think its the frame

[honest agate]

Idle speed?

It's normal for it to accelerate when it has no props, but that's way too violent

[wintry bluff]

I changed the idle speed from 5.5% to 2.5%, but that just seemed to make the drone vibrate at a higher frequency

[honest agate]

I think 5.5 is the bf default

Does it disarm instantly when you press?

[wintry bluff]

yeah

[honest agate]

I just saw the video

That is definitely the frame

Did you try with different motors

That's way too flexible

[wintry bluff]

ok

I'm going to try and reprint it with more infill

hopefully that will make it stronger

[smoky ferry]

were those sparks

[honest agate]

bruhhhhh just saw that

that came from the fc

its def sparks

[wintry bluff]

yeah

it was one of the motor cables becoming unsoldered

due to the shaking

[smoky ferry]

no thats due to bad soldering then

they wont come undone that easily

but yeah with those motor mounts youre asking for vibrations

resolder everything just in case, print the frame with more infill or stronger filament

[smoky ferry]

no

dont print the frame

[honest agate]

and check every motor separately for vibrations

just buy a carbon frame

[minor valley]

but heaven forbid he does

print 100 infill

like

no gaps

[lethal canopy]

You can print a frame 100% infil and a carbon one will be more rigid and light

Buy a damn carbon frame

You can mess with the (clearly dangerous) experimental printed frames after you're good at building the easy things lol

Starting on something like this is a disaster
