Is it really possible ?

Theoretically possible, but so much easier with the propellers on top.

Oh!

Coaxial rotors so cancel out torque (no crazy spinning) and then vector control on the props to "balance".

That also helpful.

Vectoring is simpler mechanics than cyclic and collective. The flight controller is quite a bit more complicated.

Yes I see.

Someone deleted 99% of a helicopter and it still flew 😂

@entadion 😂

Yah they been doping this with rockets been since the 90s.

👍🏻

Can it mow the lawn? 🤔

Maybe 🤔

Reminded me of a thrust vectoring project on the YT from some years back

Thanks.

Both are different man.

Okay I will check.

Upside down coax heli, ie the hard way to do it. Looks awesome.

Yeh man.

It's like a helicopter, just less efficient.

Okay.

let's make things harder...

😄

i'd invert it. The load balance would thank me.

😂

Helicopter does it

But centre of mass of helicopter is below his wings.

Yeah but this was a stabilisation issue which drones solved algorithmically years ago

Oh! Thanks 👍🏻

@MoonriseBill the stabilization principle is similar to the Falcon 9 booster or any DIY gadget with microcontroller on two wheels

@MoonriseBill Really? You are saying it's similar to falcon 9 stability system.

@vfkomarov Take a look at this video, 'guy balances champagne glass on drone from ted talk' This was from 2013

@vfkomarov 👍🏻

Doubles as weed wacker

Really?

Whats it usefull for? It had to be proven.

Of course. Good actuators and control theory. Not that difficult.

🫡

What's the use case? And if the stand breaks, you're SOL. Not a resilient/robust design.

easily

I think it's difficult then we think.

Why?

Okay But I don't think so.

There is a version of this out now - I think. It is called a HELICOPTER

Okay 🫠

Why doesn’t this exist more? (With propeller on top), seems cheaper and more reliable than swashplate helicopter

Bro, but I asked for working possibility🤔

While this stuff is always cool, it's not new. What's new now is the SCALE of how Elon Musk is achieving it. NASA tried for decades.

🧐

Yes

@wd5jlr 👍🏻

antigravity gyroscope

Hmmmmm

Of course

👍🏻

@VozimDrony

yes. it is not easy because it is so unstable. but, if your code runs fast enough, it can be done

Okay 👍🏻

At what angle does it become unrecoverable? And wouldn't that issue be solved with the center of mass below the blades... like a helicopter?

!

Looks like the ring drones flying vertical

🫥

That's a flying guillotine, I'd keep my distance!

🤔

Of course, it's a coaxial rotor craft. We've been doing this for almost a century now.

I just get to know about this today only. Thanks for reply.

垂直共轴反浆无人机 有点意思

Now show it recovering from being hit by a bird.

😑

uh ... well it's possible but it looks like someone is holding it and moving it around. and how is it still hanging midair when the blades are not moving

Yes, it feels like that.
