Simple flying vehicle script

How could i make an extremely simple plane that is just a seat which moves with WASD and E for up and Q for down?

How could i do Q for up and E for down>?

Assuming the plane is a model do a position change of its root part.
something like this
rootpart.Position = rootpart.Position + Vector3.new(0,1,0) for the Q key and
rootpart.Position = rootpart.Position + Vector3.new(0,-1,0) for the E key
