@AstleyIndustries can you build me a normal screw so I can make a land one

You would need a very huge yet light screw to power a plane... and its a bit too tedious to build so nope

Cool idea

@Kerbango i agree it does sound like there bragin but this did give me some ideas on how i might turn it

Okay that was the wrong video that was a WIP video. Here's another one I found. . I don't speak Russian but I'm pretty sure they're bragging at how awesome they are.

I saw this video it might answer your questions about the ground screw propulsion.

@kingofsteam Ok.

@FlyingThings what i dont get about the land vehicles is how they turn because if you turn like a tank with this method of propulsion then it would offset the screws and you would be constantly trying to correct it so you dont turn in one direction

@FlyingThings yes there are and i want to try that also but i want to try the plane first

@kingofsteam There are some screw-propelled land vehicles too.

n@FlyingThings not any more but if you research it the first ideas to get propulsion through water without wind was a screw instead of a propeller but then they discovered that the propeller would provide more propulsion so we use propellers today in modern boats

@kingofsteam ok, forget what i said. But, do ships really use that thing to move around?

a screw is longer and is a wound up circle a propler has sections and is not long or wound up its baically sheets of wood or metal that are tilted

@FlyingThings look at the picture

look at this if you need to see it

@kingofsteam a screw is the same as a propeller.

and the screw has to be made out of wings

by the way once your done building it send me a link
