Much like Dumbo, the Catalina flying boat, the Vought OS2U-1, was designed for one thing and wound up its service career having done nearly everything. Many are the Navy veterans who lived to go on fighting because they were 'Kingfished' out of the briny by this airplane. Unsung, it hit the front pages with rescue of Eddie Rickenbacker from the Pacific wastes. But the topper was the time a Kingfisher landed in Truk harbor, Japan's Gibraltar, in the middle of a big raid and loaded seven downed Navy pilots on wings and floats, taxied 16 miles through the ocean's open water to deposit them safely with the submarine Tang, then flew back into action.
Small, rugged and versatile, the Vought OS2U-1 was among the first airplanes to use welding extensively in its structure. Note too the use of spoilers for lateral control at low speeds when the ailerons dropped with the flaps on landing runs. Powered by a 450 hp Pratt and Whitney radial, it was no ball of fire, but in 1941 it was an airplane when we needed airplanes. Originally brought out in 1939 as a gunnery spot-ting and observation plane for catapult fleet duty, it stayed in service until 1944, and in some cases later, finally bowing to progress in the form of the helicopter.
The drawings are scaled directly from Vaught Sikorsky Co prints: one inch to one foot scale. The markings shown are authentic, pre-war and colorful. This ship represents the machine flown by the leader of Section One, Airplane Four, Observation Squadron Three (V0-3), aboard the 33,000 ton New Mexico Class battleship, the Mississippi. When shore based, the wheel gear shown replaced the usual single large float and the two wing tip floats.
Getting down to the business of building, it would be best to read the details carefully since this ship was designed to be built with the engine mounts, gear, wing spar and hook all in one beefed up unit, and while construction is not difficult, the wrong sequence of con-struction can make it awkward. With the demands of the carrier event placing a premium on ruggedness, low speed control and short field take-off, we think this ship will please the most critical fan.
Build the wing first. It is conventional in construction, using two spars of hard balsa helped our by plywood short spar gussets as indicated on the drawings. The spars and plywood spar stiffeners extend right through and key in between the engine mounts later. Plank the wing with 1/16 sheet..."

ScaleType: This (oz4910) is a scale plan. Where possible we link scale plans to Wikipedia, using a text string called ScaleType.
If we got this right, you now have a couple of direct links (above) to 1. see the Wikipedia page, and 2. search Oz for more plans of this type. If we didn't, then see below.
ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Vought_OS2U_Kingfisher
Wikipedia page addresses may well change over time.
For more obscure types, there currently will be no Wiki page found. We tag these cases as ScaleType = NotFound. These will change over time.
Corrections? Use the correction form to tell us the new/better ScaleType link we should be using. Thanks.

* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
