Hi Dan, you foreign devil!
I found my old Spinning 2 notes - basically brace the control column and rudder central until the buffet / undemanded roll stops. If nose high, full throttle, if nose low, idle power. Then roll to nearest horizon, level wings and recover from the descent.
I didn't care much for the 'nose high / nose low' assessment, so I said 'if IAS changing rapidly, move throttle in opposite sense - otherwise leave it where it is'.
During CFS time, a colleague and I did a 'giveback' session of Spinning 2 - his demo. of 'full spin from manoeuvre' was interesting - pull into the vertical from about 120KIAS, apply full pro-spin and close the throttle....
The poor little aeroplane went nuts as I sat there playing Bloggs and he tried to sort out the recovery.....
