These are exceptional models. They are faithfully reproduced in kiln dried Philippine Mahogany. Each is carved, joined, and sanded by hand. The deep, rich finish that distinguishes these models from all others is created when the up to 35 layers of enamels are applied. The final product is a beautiful wooden sculpture. Each model comes with its own desk stand. All the propellers are made of wood and will rotate. Several of the jets come with movable "swing wings", also made of wood. The World Air Corps has recently added some models (indicated on their pages) made of precision resin, as used by the military for their exacting detail. These resin models are also hand painted in meticulous detail. We offer a huge selection, and try to have the majority available at all times. However, these models are not mass produced, and some models may be available in very limited quantities. The World Air Corps, as all of our departments do, cover their products with a money back guarantee if you don't like your model when you receive it!. These are NOT small models, their wingspan ranges from 11" to 23", and if you're really into BIG,we carry a Martin/ Pan Am China Clipper with a wingspan of Six Feet.
