Quote: "Simple, lightweight engine powered free flight for the modeler who gets his kicks just from flying! any old place under any old conditions, you can't beat it! Vultee V-1A, by Ted Schreyer.
One of the most advanced and beautiful aircraft to emerge during the early 1930s was the Vultee V-1A, a single-engined transport plane of all-metal construction, featuring a sound-proofed cabin for 8 passengers, fully retracting land-ing gear, powered by a Wright Cyclone 735 hp engine, cruising speed of 205 mph, and spit flaps that allowed a landing speed of only 63 mph. The Vultee V-1A had a span of 50 feet, length of 37 feet, and gross weight of 8,500 lbs.
January 15, 1935 Major James H Doolittle flew a Vultee V-1A from California to New York City in 11 hours 59 minutes breaking all existing records for transport planes. Sept. 2, 1936, a modified Vultee V-1A named 'Lady Peace' took off from New York and headed east over the Atlantic, but radio and navigation trouble landed them 175 miles from London, and then in Newfoundland on their return trip. But the aircraft had proved its performance and ability.
In 1935 American Airlines and Bowen Airlines were both using the Vultee transport, and factory production was up to 50 planes a year. However, this success was short-lived because of the ban imposed on single-engined commercial transport planes for safety reasons, not to mention the competition from the twin-engined Douglas DC-2. Vultee tried to recoup by redesigning the V-1A into an attack bomber, but although its performance bettered existing Air Corps planes of the time, only a limited number were sold. Despite its lack of commercial success, the Vultee V-1A had made its place in aviation history and the at-tractive plane with its well-proportioned aerodynamic design makes for a fine model.
This model is the result of a desire to produce a sport flying scale model of one of the famous aircraft of the 1930's, and the author's ambition to make a low-wing free flight which led to the selection of the Vultee design. Happily, the V-1A not only turned out to be capable of flying well for a scale model, but has proved to be rugged enough to take lots of Sunday flying. The plan may seem complicated at first glance, but actually construction is basic and not difficult.
A secondary factor in the design, but of importance in the success of this model was the light weight achieved by simple structural design, elimination of detail, and silkspan covering instead of balsa sheet. What goes up must come down, and the author feels that although a heavy wing loading may not adversly affect the powered flight, it is the glide and resulting landing, or a better word is 'impact', that proves the value of a light wing loading with its flatter, relatively slower glide and the ability of the model to 'bounce' rather than dig in or shear off the extremities. In the course of extensive flying, the model (which weighs 51/2 ounces) has flown into such Vermont landmarks as maple trees, stumps, brush piles, and a barbed wire fence and come away without serious damage. Also, the light wing loading permits the use of minimum power, in this case the Cox .020.
The model was scaled up (2/3 inch = 1 foot) from a rather small size plan in 'Flying for 1936' and therefore is not considered exact scale, although the only conscious departure from scale was the addition of about 10% to the rudder area.
Construction: Balsa should be selected to give strength with lightness, all glued joints should be given a second coat.
Fuselage: Basic keel and bulkhead construction with longitudinal stringers. Cut out bulkheads in full round width even though plan shows half-bulkheads. Wood grain in bulkheads should run vertically. Take care to cut the stringer and keel notches the right size for a snug fit. Cut the keel out, splicing top and bottom near the tailwheel, mark the locations of the bulkheads, cut out a slot for the rear of the stabilizer, and glue bulkhead 'F' in position..."

Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

ScaleType: This (oz750) 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/Vultee_V-1
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.
