You got a better explanation than I did when I first asked how it worked. The MX
guy's answer was PFM.
That's exactly how I have seen how the they work in flight. Now there is an issue, the V-tail models have less overall rudder authority than the conventional tail models. Which can be an issue when you are landing at airports with a single runway, sometimes you simple run out of enough rudder to line yourself up.
The V-tails are fun to fly, but there advantages are few, you get at most a couple of knots over the convention tail, smaller engine bonanzas, and they have a knack of flying off in flight (I kid on that one, but there was an issue, that required the issuing of an AD
). It is kind of fun flying them, but in the end it's not much different than any other doctor killer, it just looks cool with the V-tail.
At worst, you screw up and die.
