Need help with Arduino Uno Drone

[mossy drum]

The motors starts spinning fast right after arming and it flips. The motor's directions are correct and the props are correct aswell. please help me.

Usually this happens when the gyro is upside down or 90° to one side, make sure the gyro is oriented correctly

If you have some way of seeing how the quad thinks he is, use that, and tilt it to one side, and change the angle of the gyro until it matches with what you are doing with the drone

what flight control firmware are you using? Something already made or something you made yourself?

[mossy drum]

I am using Arduino Uno , Coded myself(used internet refernce)

[sharp gorge]

has it worked before?

[mossy drum]

I watched a guy making arduino drone and followed him

[sharp gorge]

so you used existing code?

[mossy drum]

yes

@unreal pollen this the gyroscope I am using

[sharp gorge]

it seems like a fairly specific project, not really something standard that most people here would be familiar with. I'd recommend checking that everything is the same as the guide, and that everything else behaves as it should

yess thank you for the advice 🙂

dude

is about to go from 10 to 9 toes

imo waaay too close for a completely experimental aircraft

I'm not familiar whatsoever with DIY firmware, but I do know that everything has to "align" right in terms of what the drone "thinks." Meaning, it has to "know" the orientation of the gyro, and the props have to not only be in the right spinning direction, but they also have to be in the right configuration. There are two potentially correct orientations, referred to as "props in" and "props out." They both produce thrust downward (assuming that the props are also installed accordingly), but because yaw force is created by slowing and accelerating certain motors that are already spinning in certain directions, the differentiation between props in/out is important

I'm not sure how props in/out is defined in your custom firmware though so that part would be up to you

but yeah get the toes away from the blades. They can slice like knives haha

Thank you for the advice, ill keep my toes away XD

Can confirm, I had some funny experience with 1.6" props and 5" props at full throttle because my radio fell off my laps, let's say I don't recommend, except if you want some cool scars

After 10" sizes, you start leaving behind the need for stitches and start looking for a limb donor lol

[unreal pollen]

After 20" sizes, you start leaving behind the need for a limb donor and start looking for a graveyard

[robust sedge]

after 20" sizes, you don't need to leave anything, your life insurance company will leave you
