Knife-edge flight, sustained rudder input✈️ Plane

Knife-edge coupling — nose pitches up/down in knife-edge

Holding knife-edge, the nose pitches (and sometimes rolls) instead of staying level.

💡 The idea: Rudder deflection at that attitude is inducing unwanted coupling — a fine-tuning mix, not a primary fix.

Try these in order

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

  1. 1
    Add rudder-to-elevator (and rudder-to-aileron) mixing, tuned separately for left/right rudder

    Only address this after CG, neutral trims, and thrustline are already correct.
