Plane creation with LinearVelocity and AlignOrientation

Hi,
I started making a plane game and I tried to create a plane.
So I wanted to use LinearVelocity and AlignOrientation. But the LinearVelocity does not make th e plane fly because it’s attracted by the gravity.
How can I do to avoid that ?
To avoid confusions, my plane is a simple part for now.
