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, as I was preparing to 'step out'. This was quite near max aft allowable C of G (but within limits). I never did a full slip again, and was happy I'd waited until I had a lot of air under me to do this test (flying from a winch-only site). I read POH's with a lot more attention before flying new types. A half-control slip with full top-and-bottom dive brakes in the Austria gives pretty good descent rate. I loved flying the Austria, within the limits the book gave.
