RE: real scale flight
This discussion seems to have sorta died out, but I came into some information today that might be worthwhile.
In a prior post I related that I had talked to a former co-worker who had flown the full sized C-47 / DC-3 and I asked him about stall characteristics. In that discussion I was told that the full sized airplane has very strong buffet which warns the pilot against further angle of attack increase. Well, my friend called another of our former co-workers, who was chief pilot. That gentleman said that he had gone a bit farther into the stall regime and the full scale airplane exhibits a strong roll off when sufficiently provoked.
So there's the bottom line. The DC-3 models do the same thing as their full scale counterparts they drop a wing quickly. The only difference is that the model pilot doesn't have the benefit of feeling buffet which might warn him not to pull the stick back any further.
