Looking a Monogram kit over, all my props are fine.
I'm noodling on fixing the wing/fuselage join by lowering the wing some. I have a number of the kits and one is going to donate wings for the XC-99 so I can afford to goof up. I think I will put the fuselage together with white glue and then cut along the wing to fuselage intersection lines which are very definite. After that I will join the wings to the root segments and jig the wing up true and fit that assembly back to the fuselage, trimming the bottom of the root on the fuselage until the wing is lowered to the proper level. After that I may make a resin mold of the new center where the wing joins so I can use that on other builds. The new part would be an insert for the upper fuselage out of resin that replaces the removed area between some of the panel lines so it is easier to fit.
