PID tuning for a 80kg drone

[teal meadow]

I don't feel safe giving any recommendations, and I don't think anyone else will either. At this scale, please just talk to a professional

ArduPilot is NOT certified for use in applications where ArduPilot is effectively in control of human lives. Members of the development team must not knowingly assist in projects where ArduPilot will be in control of human lives. “In control of human lives” includes but isn’t limited to manned aircraft.

I am not using ardupilot but pixhawk 2.4.8
Where I live this was the cheapest option because my budget is very limited.
If you have contact with any professional please tell me , it would mean a lot.
Thanks

pixhawk 2.4.8

That's the name of the hardware you are running. The firmware is either ArduPilot or Px4 on that board.

Be safe.

Professionals ?
Maybe there https://discord.gg/SHsdUkbS

You will get the same quotation of the code of conduct there. You are seriously downplaying the level of risk involved.

Your safety is your own responsibility.

I will no longer be participating in this conversation. End of this.

Thanks

[pallid socket]

You are putting your life at risk and you are using the cheapest options you can find?

[knotty silo]

this is the best thing I've ever seen

[visual jewel]

Holy crap, I also have no idea how to help but that looks ludicrous!!

[austere cairn]

I have no other options mate

[austere cairn]

Thanks

[austere cairn]

Thanks

I put it on youtube please share -https://www.youtube.com/watch?v=4uEefSRd8SA

I have to ask, what is the purpose of building this thing? Are you required to build/test this thing somehow?
Seeing as you're not sure on the difference between the hardware and firmware names raises some concerns.
What size/kv motors do you have and can you provide more details on the frame?

Looks like you're already having severe stiffness issues in the frame

[hard summit]

Modern day Da Vinci over here🤣

I hope you get this working, this is sick

But get some god damn protection on the seat, dont want to end up without legs

Also it seems waaay to flexible to even fly propperly, even with a good PID

[austere cairn]

Yeah I'm thinking of adding some more rods to make it stiff

[austere cairn]

Thanks!

[austere cairn]

Haha yeaah I got some cuts in my hand because soldering of one motor came loose and altho I was just 1 feet above the ground my hand went into the prop

[austere cairn]

Surely I'll add some rods parallel to the frame to make it stiff.
Thanks for helping you all are a great community.

[boreal nymph]

Have you done an FEA analysis on the frame? Would help a lot

[austere cairn]

Can you please elaborate, I don't know what that is.

[austere cairn]

I searched for that on the net , I think we need paid software for that ....
I am very VERY budget limited because this entire project is built under 2.5k usd as my parents are providing money for me

I am just 16 I cant get money from anywhere else my parents are the only support for me rn

[boreal nymph]

Man seriously if you're not able to do this sort of proper stuff you really need to reconsider doing it.
Don't get me wrong it looks super fun and I'd love to do something like that myself but even if you aren't concerned about safety you will not be able to get good results without proper analysis

Free FEA software is available but if you don't know how to set it up properly the results aren't accurate

Crap in, crap out

[austere cairn]

Sure I get your point

[austere cairn]

Yeahh sure I'll look into that
Thanks for the help

[umbral hill]

YOU ARE WAY BRAVER THAN ME

[austere cairn]

Thanks

Is that you OP

[austere cairn]

Haha yeah bro

[pastel steeple]

Stay safe

[austere cairn]

Sure bro
Thanks
I wanna add a canopy and a parachute

[austere cairn]

Btw you from India?

[pastel steeple]

Yeah

[austere cairn]

Where did you saw my project?

First

[pastel steeple]

Here, when you made this thread.

[pastel steeple]

.

[austere cairn]

No im talking about the video

[austere cairn]

I don't have any other choice

Ik its a little risky but I have to do smthn

[pastel steeple]

Youtube

[austere cairn]

Nice

[pastel steeple]

Not a little; but alot.
Your safety is in your own hands, don’t let dreams overshadow precautions. 🙂 Take the steps you believe are necessary and also the ones that are actually necessary for your own safety. 😄

[teal meadow]

I uhhhhhh...

not gonna lie I thought this post was a joke

as dangerous as this is, it is pretty impressive

[pastel steeple]

Yeah

[austere cairn]

Surely man thanks for caring .

[austere cairn]

I agree its dangerous but I fly it very little under 3 meters of height so....
If I get help from the government I'll surely add a better flight controller of

[ancient spindle]

The danger is not limited to the height of your flight above ground.
The danger is also because of the parts being hobby grade and the electronics reliability.

At any point a failure of the prop can send flying shards.
Failure of the stabilisation or a motor desync or stutter will result in the same.

[umbral hill]

Are you dead yet

Please stay safe

[austere cairn]

nah bro

Im living great (yet)

[mystic saddle]

Still alive?

[austere cairn]

Yeah 👍
