While it has been some time ago, over 30 years ago, I don't recall anything about the stall characteristics of the DC-3 to be all that exciting. However, all we had been trained to fly the aircraft to was the approach of a stall, then recover and move on. It seems like the aircraft gave plenty of warning if you knew what to look for. I also remember the approach stall series, part flaps and partial power in a bank to be the most dramatic, as the aircraft would roll off toward the low wing and the nose would drop. Never the less if you started the recovery as soon as the wing started to drop it was a quick recovery. But it taught you to never get into that condition anywhere near the ground.
The DC-3 was/is very easy to fly as long as you respected it, which I did. I respected every aircraft I flew and the more I gained experience in any given aircraft, the more I would respect it.
As for icing, there was only one icing event encountered by me in a DC-3, as our DC-3 had no de-icing boots and we avoided any actual or forecasted icing conditions. Except for one night we came home late and encountered unforecasted icing. The accumulation of ice on the wings didn’t cause any problems, it was the instant ice covering the forward windshield that caused problems. We had removed the de/anti-ice windshield equipment as well.
So I was forced to open the little direct vision window in the forward windshield and the side sliding window on the left side so I could see out to land.
I think my nose and left ear finally thawed after my third or fourth Scotch that night.
