Plane consistently yanks around when passing -14 Degrees Angle of Attack.

137 BurgerB  one month ago

Trying to figure out why at -14 degrees angle of attack, this plane just goes absolutely ape and yanks around, regardless of center of mass or center of lift placement. Any help in diagnosing why this would occur would be appreciated.

Here is a link to the plane. I included a label at the back of the plane to show angle of attack so you don't have to use console.

    @BurgerB i was thinking the same. Symmetric wings have good aoa capabilities and they generates lift when angled.

    @overlord5453 The link is in the OP.

    I did some tinkering, and it's probably because the main wings are symmetrical and have some sort of internal limit of 15 degrees angle of attack. I made a new plane that's made up of an engine and cockpit, with symmetrical wings, and the 15 degree angle of attack limit seemed to apply to this aircraft as well.

    @BurgerB that's strange. Post it as unlisted. I will take a look.

    @overlord5453 Even with tiny control surfaces, it still has issues.

    The interesting thing is that the plane behaves fine at -16 degrees AoA, but as soon as you get to -14 it goes bad.

    14 degree aoa can take it's toll on an aircraft.
    Try limiting the control surfaces.
