1:250 Scale Plastic Snap-Fit ? Boeing 747-400F ? Length:11" Wingspan: 9.75" These models from Flight Miniatures are made of plastic and don't need any glue or paints. The assembly is very basic and takes only a few minutes. Assembly consists of nothing more than attaching the wings to the fuselage and then attaching the tail and elevators. Special care has to be taken while attaching the wings since the fitting in these models is quite tight and some pressure needs to be applied. The pressure needs to be applied on the wings and onto the fuselage. Do not, for example, hold the wings from the engines and apply force like that since this will damage and/or break the engine. The level of detail is very nice and accurate. Wings will show the different panels and sections just as the real thing. The coloring and markings are not decals, so they won't peel off. For the people who are really observant, engines are accurately proportioned and the type of engine is also accurately represented. These type of models are the type which one can see in airline offices and/or at travel agents (when they were still around). These are not toys, they are not intended to be played with since they are very fragile. However, the constructions is so simply and because they have no moving parts, that casual "flying" (and making noises) will be fine, even if done by a child. The box measures 11 inches long by 2.5 inches wide by 1.5 high. Please note that this is a collector model and is not recommended for children under 8. The 747-300 features a 23-foot-4-inch-longer (7.11 m) upper deck than the -200. The stretched upper deck has two emergency exit doors and is the most visible difference between the -300 and previous models. Before being made standard on the 747-300, the stretched upper deck was previously offered as a retrofit, and appeared on two Japanese 747-100SR aircraft.[160] The 747-300 introduced a new straight stairway to the upper deck, instead of a spiral staircase on earlier variants, which creates room above and below for more seats. Minor aerodynamic changes allowed the -300's cruise speed to reach Mach 0.85 compared with Mach 0.84 on the -200 and -100 models, while retaining the same takeoff weight. The -300 could be equipped with the same Pratt Whitney and Rolls-Royce powerplants as on the -200, as well as updated General Electric CF6-80C2B1 engines.
