Adverse yaw — nose swings the wrong way in a roll

Rolling one way makes the nose swing the OPPOSITE way instead of coordinating into the turn.

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 aileron differential (more up-throw than down, ~5° less down)

   Fixes the drag imbalance directly at the source.

2. 2
   Add aileron-to-rudder mixing (~20-50% depending on severity/wing type)

   Coordinates the turn electronically — symmetrical wings need less, flat-bottom wings need more.

General RC tuning guidance — your chassis manual's own tuning chart is the final word for your specific car.
