As being of taildragger gear the AoA can't be rised higher than when sitting on the ground, hence the height, wich have to be rised together with the lenght of the fuselage to kee the same AoA.
However, judged on the ladders there might be a little more than two meters between ground and leading edge and I think a grown man can stand upright under the wing of a DC-3, hence the difference might be less than what it seems :-/
