DJP,
New member here. Thanks for the excellent spin information.
Purchased an Aerobat years ago and received spin/aerobatic training for flying basic aerobatics in the Aerobat.
Going through positive G spin/aerobatic training with Bill Kershner in his Cessna Aerobat years ago. After 10 to 12 turns during the spin, engine would stop running due to centrifugal force un-porting fuel pickups in the wing tanks, the propeller would stop windmilling, too. Very quiet! We recovered after 21 turns. Bill liked to joke saying before re-start, open the window and holler "clear prop"! The Aerobat would lock into the spin and the Beggs/Mueller spin recovery technique would not work. Bill taught me to always use the NASA recovery technique in the Aerobat.
Received a little spin training with Bill Finagin years ago in a S-2C. We started out with a positive G spins, transitioned with full forward stick/opposite rudder into a negative G spin, transitioned back again to Positive G spin with full back stick/opposite rudder. Did two or three sets of spins like this, it was a blur. Made recoveries in the Positive G spin using the NASA/PARE technique that Kershner taught me.
The Pitts is loads of fun to fly!!!!
