While we all are in daydreaming mode ..... .. .I don't think that anyone has mentioned the stall scenario associated with a very high pitch rate ( 60-70 deg/sec minimum rings a bell in the fog at the back of the mind). The initial stall leads to a vortex above the wing which causes reattachment and permits further alpha increase.. .. .I recall reading an interesting article on this subject in the RAeSJ several years ago. Apparently a problem with helicopters more than mere aeroplanes which have some difficult generating the sorts of pitch rates required.
