Interestingly I'm currently doing powered aeros in a R2160! Not spun it yet tho..
A likeminded soul at last!
Spinning the R2160 is entirely conventional. In fact, now that I'm doing aeros in it and finally learning what those footrests are for, I find it very hard to make a nice, clean spin entry. It's as if the elevator runs out of travel before reaching a low enough speed for a nice entry. Particularly when the aircraft is comparatively light: one-up and half fuel. Even when you whack on the rudder it is really hesitating to start the spin.
Once in the spin though it's all conventional: release the pro-spin controls a little after three quarters of a turn and you are out of the spin at exactly one turn. Push to the vertical, hold one second, pull straight and you've got about 110 knots - perfect for the next figure in the sequence.
