Hi Gerald. I do not recall VECO ever puting "plans" in any of their kits. Cut aways, iso views, but no true plans. The idea Gil Henry had was if you wanted a new plane, you bought a new kit. I guess it never occured to him that some guys traced his kits and made their own plans, so maybe some "olde fahrt" out there has tracings. You might try Tom Dixon as he used carbon paper on his first sets, which goes back a ways..
Or if one is desperate, you might try the archives at AMA. They do have the entire collection of John Pond and he collected EVERY plan ever put out, CL, RC, free flight, rubber power, HLG, you name it he had it.
