My plan: to reduce the fuselage length in front of the wing, to reduce a little the fuselage width, to ignore the small difference in fuselage height; Use Milliput or similar to re-contour the nose. For the wings, to get rid of the glove. Tail elements, wing to fuselage fairing, engines and other details to think about later.
What do you think? Anyone attempted it? I'd be interested to share ideas about the conversion.
As refs I have Merlin Woodman's guide on converting C-135 to 720 on Airlinercafe, the Ultimate Boeing 707 Guide by David Hingtgen on the same forum, a PDF shared by Romeo Alpha Yankee on the 1/72 Boeing 727 from Heller Boeing 707? topic and a lot of stuff from books and the net. I am waiting for René Francillon's book that is travelling from a bookshop in Chicago to Portugal... A stations diagram of the fuselage would be very helpful! Anyone knows if can be found somewhere?
