Which BodyMover should I use for an aircraft?

So basically I was trying to make realistic aircraft physics but encountered too many problems and now I am absolutely confused and baffled. I started off with setting the velocity to the engine's lookVector which worked really well but seriously counteracted the effect of another part's force e.g. (throwing huge parts at the plane didn't make it flinch whilst flying) so I decided to make a limiting system which slowly changes the velocity to get it back to the correct speed and limit it but obviously it didn't work and was hard anyways. Next I tried BodyForce, this made it move infinitely fast and crashed my computer (horrible idea) and then I thought why not BodyVelocity but this also made it move infinitely fast despite Roblox's description of the mover being: "such that it will maintain a constant velocity" not "it will constantly increase it's own velocity". So I decided that it may have been something to do with the wings but came to no avail after deleting them. All I want is to make the engine try to move itself forwards at a specific velocity and direction, also I just want to make the wings do the same thing but with a lower velocity and increasing force. Thanks!
