[NSRCA-discussion] Snaps

That judge must be used to the F3A “twinkle snap”.  

BTW, one F3A judge at the Nats gave me a zero for making a nice landing just outside the “landing zone”.

Hence the deep wallow before the autorotation that results in the displacement of the flight path…to their advantage in this case. They used to do the two-plane formation snap on take-off, which always impressed me to no end.

A Pitts S-1 is somewhere in between. The Citabria, needing full "con" ailerons, will pause for a split second, then autorotate in a flash with surprisingly little displacement. So 10 different planes will all autorotate differently, some imperceptibly. Accordingly, many full-scale pilots snap with ailerons "pro" instead or with the traditional ailerons "con". Heck, most full-scale competitors get 10's on spins and they are literally flying/slipping the plane down the spin…never having stalled at all.
