djpil,
the Chippy is an intriguing machine to spin that's for sure... Looking through the book, all this reference to forward, if not full forward stick to initiate recovery didn't conform to all the others I have spun....but it's try, full opp rudder will not get a Chippy out...This one had the flow strips down the fuse to the leading edge of the horizontal stabiliser. No wonder so many crashed, pilots couldn't get their heads around it.
I practiced them in this machine from 7500ft as I wanted to look at use of power and aileron etc. Very, very interesting, couldn't be any more different!
