I have a little delema at least for me. I have an old TF P-51 kit and have it mostly framed up and most of the wings built up. My problem is on the flaps where do they hing at on the real P-51. Are they kindof like the P-47 or is the piviot point a little back from the leading edge of the flap. I just don't know can you help.[]

Well you can do a search on www.dogpile.com or you could do a google search. But I think you'll like one of these two books that show a lot of detail.
Walk Around P-51 Mustang a Squadron Signals book.
Aero Details North American P-51 Mustang.
Both books show a lot of closeup photographs of such stuff. Aero Detail is the better of the two, I think, and a bit more expensive as well.

nchrome, The P-47 flaps are actually fowler type of flaps and the P-51 are not. The mustang flaps hinge on the leading edge of the flap section. Check out Mustangsmustangs.com for pictures of stangs.

Which would mean that the hinge point would be the center of the flap's L/E radius, like a rudder?

Thanks guys thats the info that I needed for my P-51. Now I can finish the wing and get the wing flange finished sos I can glass the fuse and get this bird done and ready for spring. I also have about five other planes that need to be finished but am trying to finish this one first.

rich, to answer your question.. yes. Like a rudder, sorta. The hinge is right on the leading edge as much as practical.

This should help! It is the D model if that makes any difference.
