RE: knife edge spin?
Basically the same thing for me. I always end up at half throttle, full down elevator, full right/left rudder and full right/left aileron.
I just played with it on the sim and that is precisly how it worked time after time. Just pin the elevator/aileron stick in an upper corner and at 1/2 throttle or so, give the same direction of rudder input as aileron.
