The Pavla engine parts were not much of an improvement over the Hasegawa
parts, I won't use those if I build another B-47 as the Hasegawa parts are
pretty good. The cockpit is a big improvement, however
getting it fit correctly was difficult. Not a lot will be seen through the
small cockpit opening, but enough to be worth it, especially if you want
to have the crew door open as Hasegawa just left a big open space there.
