i didnt reverse the engine, i rotated it and change to -pitch
and yeah i tried disabling the top one, the bottom one didnt produce thrust
i rotated back the bottom one, still no thrust

the swash plate

@Convex not the rotor,
the base of it, that has bearing for cyclic pitch, its too big

reverse rotation in rotors doesnt change the way of thrust, so use 2 stacked, one with reverse rotation (you can also use one where the engine goes, one with reverse rotation and the other not, if you want them to act like regular engines you have to change in the settings vtol for throttle)

@griges if you want the rotors to be small you can copy the diameter of a regular engine

do you know how, pls teach me

@Convex i was want to use heli rotor at first, but i dont know to scale the headhub thing
also i havent got my hand on one, so it kinda complex to get familiar with
but yes i didnt think of asking how to scale the hub, the cyclic thng 😂

maybe use heli rotors?

mass scale 0-3 didnt effect it 😭
i need more powahhhhh,
lowest jiggle started at 502power,via slider
but at that power the aircraft wont even lift

@griges
Its probibly a combination of the engine power and the rotator.
Maybe try giving the engine a mass scale of 0?

@TheMouse the wing has joint rotator on it if i connect to main body
i tried connecting it to everything elses on the wing section, it's still like that

monsnotamonster said its because the engine power, but i needed more than current 😂

Maybe its only attached onto a fuselage wing?
Try adding some connections from it to the main body of the craft?
