@edensk oh ok

@DDVC never use mass 0 on props

@Destroyerz117 alright thanks

@DDVC yeah I'm really not sure then, you should test by using normal props and slowly changing them to be like your current ones to see what causes the issue

@Destroyerz117 oh yeah, i also rescale the prop to 0.25,0.25,0.25, make the mass and drag to 0, and make the maxRpm 30000. Is that do anything?

@DDVC not sure what the cause is then, try disabling collisions on the fuselage cones as well maybe?

@Destroyerz117 only the prop that i disable the collision, and that's a fuselage cone

are aircraft collisions disabled? also are those hemispheres or fuselage cones on the front? If they're hemispheres make sure bounce is turned off and collisions for them are disabled, also that the props are attached to fuselage not hemispheres
