I have seen more than a few attempt the spinner touch maneuver, but they apparently were either going tooooooo fast, or didnt have the reverse pitch props

. For some reason, they always hit a lil toooooo fast to recover :spinnyeye. I think a few of them were unexpected though. The spinner touch turned into a spinner penetration, or shatter.
In all seriousness, I doubt the spinner touch would ever become a reality, due to the inherent instability of the plane in "reverse", as well as what effects the instant change of thrust would produce. Would it create a reverse torque roll situation? How much yaw would be produced, and which way would you even attempt to correct it. Look at how hard a tailslide is with gravity on your side, much less going against gravity, and the normal flow of air over the surfaces. But it would be cool to picture. I mean, were people talking about the feasibility of the torque roll in 96, before Quique did it at the TOC? Maybe a mini turbine/turboprop combination with thrust vectoring?
I would like to see someone do a hover, do a complete cartwheel, then back into hover. Actually, I would love to be able to do it myself, but would settle to watch someone else do it for now

. Don, that could be something to work on for the AA format.
