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,

The Austria SH-1 POH/FM cautions not to do a full slip since the wing turbulence can mask the entire tail. I did it - once - at 5,000'; in full slip, the elevator and rudder went limp and wagging the stick did nothing. Cycling the dive brakes did nothing. About 1,500' later, it spontaneously decided to fly again

I found that the original Janus did something similar in a full-on slip. Elevator and rudder both stopped doing anything. However the result was that the nose slowly pitched down and it accelerated out of it.

Not something you'd want on short final.

But it was only on a really aggressive slip, with a bit of momentum in the yawing. I don't know if you'd get there with gradual application.
