flaps with bearings on phys bearings makin thrust

[vital galleon]

I don't know if this is alredy implemented and my game just ain't working but i tried to make a variablee propeler with flap bearings on a phys bearing and it just didin't produce thrust

[crystal atlas]

use wings

[knotty beacon]

they wont produce thrust if they are at a neutral angle of attack, tilt the flaps with flap bearings, use wings or tilt the wings with flap bearings for maximum thrust
