Don't know if I should jump in here or not, but I remember a fatal Austria accident where the pilot was attempting a full slip to landing. Probably holding full aileron and opposite rudder as necessary to line up with runway. As the V tailed Austria crossed the fence, it suddenly pitched down hard and the pilot was killed. There was some discussion about a sudden application of full rudder (one ruddervator up, other ruddervator down) may have stalled the up member, resulting in full down input from the remaining ruddervator.
Something to think about if flying a V tailed bird,
