1 1/2 turn to stop the rotation of a developped spin using the correct technique....
Cap 10 and Extra200 need 1/4 of a turn to stop, and both aircraft will stop even if stick is held back during application of opposite rudder though when experimenting this beware of secondary spin in other direction.
Both aircraft will stop spinning if controls are released and cap 10 if trimmed to 150 Km/h before spin entry will also recover by itself to straight and level in a hands free released controls situation.
Depending on density altitude and weight both aircraft loose around 3-400 ft per rotation + 5-800 ft for recovery to straight and level.
Spinning and spinning behaviors are predictable, what is often unpredictable are the unconscious inputs pilots exert on the controls with often detrimental consequences.
In all developped spins training sessions, in typical 5 to 6 turns spins, all pilots with little or no spin exposure unfailingly either freeze at the controls or exercise unconscious inputs, the most common being not keeping the controls to the stops during the maneuver which in the above a/c leads to a spiral.
A spiral can be deadly if not recognised as the recovery from a spiral applying spin stop recovery will aggravate the situation.
Oldwives tales abound about the difficulty of exiting from a spin. An A/C will either recover or will not recover. And if it will recover, provided within the mass and balance envelope, it will do so exactly as stated in the Flight Manual.
Spin training is feared among the instructors comunity, I have seen Certified instructors demonstrating the spin during the FI course recovering as soon as the wing drops after the stall.
It takes a couple of flights -It has to be done in stages- with a real aerobatic aircraft fitted with oversized tail surfaces, and a real aerobatic instructor with experience, to demistify the subject and do away with the fear.
Too many perfectly recoverable spin certified and even aerobatic aircraft have been lost with fatal consequences, because of this lack of proper training. And this is still being largely ignored.
