Ok so im working on a F-15 but when I pitch, the plane just trembles and it simply really doesnt pitch well. Its been a major problem with most of my planes... can someone help me plz?

    @HenriBobby So you want to improve the pitch performance of this F-15?
    There are several ways to improve pitch performance
    1 Bring the center of gravity and aerodynamic center closer to the limit where the airplane can fly without spinning
    2 Install the elevator on both the primary wing and horizontal stabilizer (Set the primary elevator invert to Yes and the stabilizer elevator invert to No.)
    3 Set the elevator length to 20%
    Control Surfaces length can be set within 10 to 90%
    However, if the length of the elevator is too wide, the pitch performance will drop because the wings will stall
    The optimal elevator length is 20%

    @MMDerK yes i knew this is what is working but the plane is WAY LESS agile... it’s hard to just pitch... and it’s extremely long to loop and all... I was just wondering if there’s any other way.

    All-flying tail wings are less stable
    Increase stability by lowering the range of motion and operating speed
    The ideal I have reached after testing is a movable range of 10 ° and a rotation speed of 40% (This is my personal idea, so you don't have to follow)
