I'm thinking the adverse yaw would only work with downwind ailerons.

"Dale" wrote in message news:me- Aileron up deflection
on the upwind side (into the wind)
didn't help (and thinking about it, I don't think aileron would assist
in a weather-veining situation). I applied full opposite rudder and
that wasn't enough. I actually had to apply light braking on the
opposite rudder to get straightened back out.

Aileron will help somewhat to counter the weather vane....adverse yaw.
