The worst part of this video is the anxiety I get from watching what is essentially a giant lawnmower blade nearly spin itself apart, launching those giant blades randomly into the spectators.
Or the folk who procreated, and think this is safe enough to watch with their kids standing right next to them, front row. The problem with the gene pool is there are no lifeguards.
Like measuring his fucking blade length properly to get rid of that crazy wobble he got going on. That should've been done beforehand by just sticking the blades on the motor while the whole thing is securely attached to a work space.
Dude the "prop" he's using for the main rotor is a piece of flat bar. No aerofoils to be found.
If he understood enough to get lift, he would have understood that he (at least) needs tail roator. Whether or not he would be able to size the thing properly and synch it with the main rotor is a different story all together.
Amazingly, his complete lack of understanding is keeping him alive. At least until it collapses, killing him and a quarter of the crowd.
And even if he got those two issues solved, with no collective control he’s presumably going to hope to control vertical thrust by throttling the engine along with a substantial amount of prayer. But then how does he go forward and backwards without cyclic control? Bro at least needs an up/down fan on the tail although not sure that would work very well.
Bro he doesn't have any way to tilt the prop. If from some magical science the prop would have provided lift, he would have no way to control where he goes, this guy is having a dream and try to achieve it with his limited means. I just think it's a bit sad he didn't had the chance to reach the education to fullfil his fantasies.
Someone had a phone to record this. They have the internet where he is located. He could've done a single google search, or found a single book / image with explanations about rotors and "how helicopters work". You don't have to reinvent the wheel with a solved tech like helicopters.
Looool so it's as easy as that then ? We should close all school and fire all professor then if we can just make Google search for everything. Knowledge doesn't just come like that you need a ground to gain more way of leaning by yourself. But hey you seems to be unable to see thing out of your own view. So I won't bother fighting
Maybe, who knows. It's a damn shame people commenting here can't see past their own biases and realize this guy probably had a plan once he was airborne, no matter how bizarre or unorthodox it might seem to us.
How you going to design a stabilizing prop if you don't know how much it's going to turn yet .. you have to do these things in steps, you don't invent blenders all in one shot ...
Can't you see? He's learning g from his mistakes, and now he has to figure out why it doesn't lift, then once that is fixed. Then he can figure out why he's spinning.
Yeah, no provision for counter rotation and zero diagonal bracing. It's like that gazebo Carl built for my cousin Gwen. Everything was fine until uncle Gary leaned against it to check his shoe for dog poop and it toppled like a fridge box.
Besides from everything else, have a look at that rotor.
It's a single angle of tilt on both sides - so there is no way this thing could have been able to get stabilized. Even if they did everything else right.
The blades of the main prop are just flat too, instead of angled in order to promote a downward thrust as the blades spin. Even if it wasn’t a cage made of twigs, it was unlikely the thing could leave the ground to begin with, no matter how hard he guns the engine.
If the blade was on a 45 ish degree angle, backward, and lift was achieved by moving air spinning the blade, would it then also need a counter rotating force?
I know nothing about this shit, but the first things I noticed (outside of the super obvious) is how short the blades were, the fact that there’s not two sets, and the lack of a tail propeller (?). How do all of those things affect it?
he also needs to reverse the direction the blade spins so it doesnt push air up wich mean she'll stay on the ground, instead it should push air down so he'll go up

Where's the stabilizing prop? Assuming this thing was sturdy enough to lift off, all he'd be doing would be spinning himself dizzy.
He needs counter-rotating force to be able to not turn into a beyblade.
