well i got the concept of "piston with airbrake"

I have no idea on pu=iston with airbrake (maybe I'm just too dumb to figure it out)

alright, ima experiment with those methods even tho no idea of what is the piston with airbrake one is lol? @edensk

There are at least 4 different "electric" propulsion methods.
All of them use gizmos like airbrakes, pistons, rotators, shocks... (One of them also uses wings).
.
It's all about pushing air back. For example, a piston moving an activated airbrake that's pointing backwards or a rotator moving wing parts like a propeller.
.
I'm pretty sure randomusername could explain it a lot better than me though.

I'm tot sure how but it uses negative air brakes and pistons

cool stuff using airbrakes makes power without consuming fuel

@randomusername

I know someone that can help
