Best answer: the United States had no need for one. These kinds of large wing-in-ground-effect craft, while impressive, really serve no military purpose and provide no major military advantage for the US Armed Forces to possess. Aside from the internal Great Lakes, there are no major bodies of water within the United States of America where such a craft ...

According to the Seaplane Pilots Association you can operate an amphibious airplane on hard-surface runways with a land class rating but need a seaplane class rating to take off or land on water, and vice versa. As far as the regs, it seems that the airplane can simply be considered either land or seaplane class depending on how you are operating it.

One reason the US never pursued this design is that it can't operate effectively in rough seas. It needs a relatively calm surface, which limits where and when it can be employed. A potential opponent can plan for this shortcoming. In the early 1980's, there was a US Navy plan to conduct flight tests using the Hughes Hercules aircraft, to study ground ...

Your model is based on the FX-803 Piper Cub model shown in this video. It's made from expanded polystyrene wings and fuselage, with a two channel radio that controls thrust from two motors mounted below the wing, with overall thrust controlling pitch and differential thrust controlling yaw. There are no moving control surfaces, and the propeller on the nose ...

They are flap track fairings, which contain the flap mechanism. They've already been discussed elsewhere on this site. You can also see them in this photo. Image from airvectors.net They actually reduce the drag by enclosing the flap mechanism.

Seaplane air taxis only work where the logistics situation and market can support a business case for that kind of service. It's an expensive way to travel, so there has to be some kind of benefit that makes it worth the cost to the traveler. This works in the Seattle area and the Lower Mainland of British Columbia where you have large city centers with ...

This plane appears to have no moving control surfaces at all-- it appears to be controlled purely by differential thrust from the two wing-mounted motors. You could consider modifying the horizontal stabilizer to give the plane an elevator, even if just works as a ground-adjustable trimming device. You need to fix the elevator in a slightly lowered ...
