Problems with dev. versions from aprox. 0619

[crashlander]

Hello!
My setup is Quad X, promini, original WMP, TGY Plush 10A.
My quad was flying stable and good with dev versions until (aprox.) introduction of MAX_CORRECTION.
Later versions have known problems with back flips when MAX_CORRECTION is set low (100) but when I set it high (500)
Quad loses power/lift (weak throttle response) and also stability (with same PID settings as before).
I can observe same behavior also with latest r214 dev version (without MAX_CORRECTION option).
