Beggs/Mueller only works on aircraft certified for spins, because those aircraft will naturally exit the spin. Planes slow to exit the spin (like my Mooney http://www.mooneyevents.com/spins.html) need brisk full forward elevator. And even those certified for spins, with B/M, the CG needs to be far enough forward that the aircraft will nose over when the rotation stops. Even then (and I've posted this before), once the spin stops, you still have to break the dive without exceeding Vne (too slowly) and without a secondary accelerated stall (too fast).

here's a video of me in upset training recovering from an inverted spin using B/M: https://www.youtube.com/watch?v=HlVFhkQmXng
