High-AoA maneuvers (loop tops, hard pull-ups)✈️ Plane

Unintentional snap roll / spin tendency

The plane snaps into an unintended roll or spin during hard, high-angle-of-attack maneuvers.

💡 The idea: Excess elevator at high AoA is stalling the wing asymmetrically.

Try these in order

Make one change at a time and re-test — that's how you learn what your car likes.

  1. 1
    Reduce elevator throw or add expo at high rate

    Removes the excess input that triggers the asymmetric stall.

  2. 2
    Move CG slightly forward

    Aft CG aggravates this tendency.

  3. 3
    Keep entry speed up before hard pulls

    More margin above the stall before you ask for the maneuver.
