Hello!
I am making a realistic plane system. How do I calculate min. required force to lift parts in a model?
Since you haven't attempted it on your own, I'm only going to give you the theory on how to do it in steps:
1 Calculate total mass of the plane
2 create a body force or you might already have one in your plane
3 set the force of the bodyForce so that everything is 0, except for the Y value which should be the totalMass * workspace.Gravity
