Hi Murray,

Private reply off list. 
 
Could you provide me the link to the "Beast" you mentioned?
 
Thanks.

  It works on all Pitts models. Just like in the video clip if there is an overcontrol applying anti-spin inputs a secondary opposite spin will develope. That is, if a positive spin is overcontrolled a negative spin will occur. Vice versa for a negative spin. The Mueller-Beggs recovery is designed to bypass this condition by instructing you to let go of the stick. An overcontrol is impossible with this recovery technique. Problems occur when a pilot thinks he is in a positive spin when in fact it may be negative as they look almost identical from a cockpit POV, especially if the spin ensued from a botched maneuver. Thinking he is applying anti-spin control inputs my be exascerbating the spin mode. Panic finishes the excercise. In full scale acro it is absolutely essential to get spin training if you want to live to a ripe old age. Luckily when we do this with a model 99.999% of the time we just walk away with a little lighter wallet. One of the reasons why I switched!!

  Have a look at the clip of the "Beast" accident. He was a very, very experienced pilot and see how the secondary spin occurs in the attempted recovery.

    Including the Pitts S-1-2??  I lost a student (not flying) to a Pitts crash one summer -- don't know for sure what he was doing, but rumor had it he spun in...

      This is a very good re-visit of the Meuller-Beggs emergency spin recovery that is taught in just about every aerobatic school around. Power off, hands off (let go of the stick completely) and step on the hard rudder. If the rudder feels soft and mushy, you've got the wrong one!! Interestingly enough the only tested aerobatic design that does not recover with this technique 100% of the time is the venerable Citabria! It requires anti-spin control inputs to guarantee recovery.

      Cheers
