Just watched the video on Youtube. Very impressive!

I clicked to watch the first few seconds out of curiosity. Watched the whole thing.

Cool idea. We need more stuff like that. Maybe one day we gonna have some novel design
Ps. I would like to see it outdoors with wind.

I found that most of the time, the best design is from nature. The people who think basic research is a waste of money are idiots.

Dude rediscovered the helicopter

It's rather, created a tiny alternative to a swashplate and a tail rotor that pushes the limits of tech to do all that with just a fixed motor and a single two-blade rotor with just three freely articulated pins total (zero servos, control arms etc), plus complex electronics.
It is innovative, and it's not like the large complex helicopters that we usually use.

Helicopters have at least 4 motors just like “drones”. Any basic flying machine needs at least 3 or 4 motors.
It looks like this design uses tricks to make time an input to replace some of the needed motors.
Edit: since people don’t get it, I’m talking about the swashplate which this design doesn’t have. It has an additional 3 actuators (motors) and is needed to control a typical helicopter.

A classic helicopter in it's simplest form only has one engine. That one engine is coupled by gears to the main rotor and the tail rotor.
There are certainly helicopters with multiple engines, but I'm not aware of any that have dedicated engines for the tail rotor and the main rotor.

It needs three more to steer the blades. I said motor, not engine.
It’s true a human can do that on the lightest and smallest ones but a human is a motor of sorts too.

I mean, if your counting muscles than even a bicycle has ≈ 600 motors. That seems like a bit of a silly definition.

What helicopter has 4 motors?

You need one for up/down/left/right
Duh

u/Ndvorsky 1h ago
You’re joking but yeah, something has to make the helicopter move around. They have 3 more actuators to make it go up/down left/right forward/back.

You're going to have to expand on that, since rotary wing aircraft like the EC130 are single engined.

I suspect you could make some pretty money from this with interest from military suppliers.

So a helicopter?

u/rock_crockpot 5h ago
Heli’s have two props. Don’t forget about the rear one on the tail to counter spin.

u/CMDR_omnicognate 5h ago
in fairness, not all helicopters have a tail rotor, McDonnell Douglas make some that basically use low pressure generated by the main engine to push air out the side of the tail. it accomplishes the same general purpose of a tail rotor, just without having an extra prop. Though i am being a bit pedantic with that since they're not exactly common.

u/rock_crockpot 5h ago
Well, I can get down in the pedantic mud and play too! Even though you may not see it - What do you think the main engine is powering to push the air out of the side of the tail?

That still uses a separate fan/prop in the boom. The only class of helicopter that doesn't have two props/fans/etc is the early reaction drive designs that use the bleed air from the engine directly. The design was never popularized.

It's rather, imagine a car that has only one wheel and its motor is directly connected to the wheel (no transmission, no steering system, no differentials, nothing, just a dumb straight axle), there are almost no moving parts except a few articulated hinges, and it can stay upright, drive, stop, accelerate, turn, and do other things that cars do. Just because of the smart shape of the parts and advanced electronics.

No, a helicopter has 2 motors as well as a more complex assembly attached to the rotor.
Literally the first 30 seconds of the video.

Helicopters don't have 2 motors, some do, but that's not the requirement. They have 2 rotors, the tail rotor is driven by the same engine/s that drive the main rotor. Also, rotor less helicopters exist. He also from his own video basically remade a swashplate but in a slightly different manner. One that is very cool, but he's still made like, 75% of a helicopter, then called it a drone. Impressive as hell still

Sometimes I think I'm good at a thing. Then I see these people. I'm glad he's not some villain making it a secret terror project. Folks like this person move technology forward and bring everyone along. To have the talent and the generosity to share it is pretty great.
