so, I have a plane which is pretty good(month 3 in and still no where near finishing), and one problem with it is it decends slightly when the AoA is level or close to level. I dont want to increase the thrust too much because it might make the plane go the speed of light so I wanted to make the horizontal stabilizers and elevators tilt and constantly adjust to make sure the plane doesn't sink.

If theres any smart people who know how to do this pls help me(gimme the code) because funky trees scary :(
