Jeepers, that's beautiful, and huge! I built the B-36 and had to hanging on my ceiling for some years, before it got trashed in a move. I really like the way you've painted the BUFF. Remiinds me of the 1:1 version at Castle Air Museum, formerly Castle Air Force Base.
I loved working parts kits as a kid- I never could get behind the "I glued all the working parts because I'm a modeler, not a toy maker" comments one used to see in Scale Modeler... Back in the old days I told people that what I built were 'toy airplanes" because I absolutely intended to make the working features work, it all possible.
Having said that, is this build limited to airplanes, or are cars, ships, armor, dinosaurs, etc, also allowed?
My favorite classics with moving parts, that I build myself, mostly in the classic era, are:
Revell "TFX" F-111A/B - complex, retracting, landing gear; swing wings; detachable escape capsule; radome removable to show generic Revell radar (same as A-11/YF-12 kit...) Still one of my favorites.
IMC Ford GT/GT Mk II race car- doors and hood and trunk (in front) all pivoted open. Steerable front wheels. Issued in the original GT-40 shape, then the -as--prepared-by-Carol-Shelby version that won Le Mans 1-2-3 in 1966, with significantly different nose and aft bodywork. Re-issued again to commemorate the John Wyer/Gulf Oil light blue and orange cars that won in 1968 and 1969.
Monogram SBD Dauntless. Five segment airbrakes, retractable main gear, rotating prop, turning wheels, movable flexable mount machine gun, dropping bomb! I got two of these for my 10th birthday, when they were brand new. What a great kit! They came with TWO bombs and with two kits I had four total- so I glued a pin into one of them and would bomb balloons in the family room.
Tamiya Matra MS-11 V-12 F1 racer. working suspension, small, flexable, springs represented the brake lines, clear plastic tubing for fuel injection, electric motor inside the V-12, gear box inside the gear box, the engine could be installed and removed, along with the axle shafts. Each axle shaft had two Hooke joints, tires were semi-peneumatic (ie hollow, flexable, rubber). 2 AA cells went where the driver's legs should bave been- with the batteries installed, it could crawl aound whiring...
Tamiya 1/25(?) Tiger tank. fFully articulated suspdsssisons. My pal Bill S. had one, I loved playiug with it.
