Other people have given more practical solutions, but did you know, Roblox recently introduced Aerodynamics into their Physics Simulation?
And, with it, you can make physically-based helicopters that generate lift through actual, rotating blades!
No VectorForces to be seen! Purely the rotation of parts that are slightly angled.
Obviously, this offers less control to the developer and can be more difficult to wrap your head around than just directly applying a force, which is why I implied it’s less “practical”: Sure, it’s more realistic, but it could just cause more problems for actual Game Development.
