The sudden wing drop visible in the video is exactly what happened to me numerous times during stall testing of a turbine DC-3. Recovery was gentle if initiated before the stall had occurred. If the stall progressed to loss of control, it was demanding to recover with minimum upset. Recovery from a half turn incipient spin in t DC-3 will use up around 2000 feet of altitude for my experience.
In a standard powered DC-3 the forward push to get the tail up can hardly be called "gentle" when heavily loaded. Now this airplane was nowhere near that condition but I have flown them where it takes everything you have to push the tail up. As a matter of fact in those conditions you have to use the trim wheel to get things going. As for directional control, as I mentioned in a separate post, the ailerons are highly effective for directional control and MUST be used, rudder alone cannot overcome a large swing. And we routinely used aggressive differential power when needed to keep the thing straight when aerodynamic control input was not sufficient.
