IF789: if I may play devil's advocate for a moment.
Even when one is trying to "power out of a stall," one still has to control pitch to prevent restall. Pitch + Power = Performance still applies. Low to the ground, seems to me that there is a risk of negative training taking place if use of power and pitch to unstall isn't well taught.
How the recovery, or return to flight away from stall when one gets a stall warning, is taught is as important as what it taught.
