need help with control surfaces
i made a very, very small jet. its 2.6m x 1.5m x 0.8m. when i'm flying it feels like my elevation rudder locks and then i need to fight to pull up or push the nose down. if someone who knows how the aerodynamics work better than i do, it would be greatly appreciated.

I imagine it is the difference in size of the surface area of the wings and the elevator. I imagine because i don't know for sure but the drag of the trailing edge of aero parts dictate how the part slices through the air and as you increase speed those forces increase and have to be overcome by the other forces you will use to change the direction like the elevator.

So unless you can overcome the tendency of the larger wing parts to travel in the direction opposite the drag the plane will tend to kind of snap back to the path opposite the trailing edge of the largest aero surface or control surface.

You can always segment the wings and reduce the total segments that have aero toggled on to reduce the forces you must overcome.

let me try something real quick in that case

well i tried moving the elevation rudder out of the way of other parts, changing the shape, and also seeing if maybe it was the movement speed but nothing really changed

The only easy way to overcome the problem without changing things is duping the tail aero parts in place to increase their aero strength until you reach the level of control you need.

jokes on me i guess, i changed the length of the tail rudder piece and i think what happened it that it wasnt catching enough air until it got to a certain angle, this game can be a little "silly"

The forces probably increase as the angle increases off of the angle of travel.

The drag probably also increases at the same time so if your control surface must be rotated off the angle of travel too far to reach the amount of force you need you will probably notice a speed decrease.

well thats solved i guess

Yes.
