The Bellanca YO-50 was a United States prototype observation aircraft, built for the United States Army in 1940. Typical for aircraft of its type, it was a high-wing braced monoplane with fixed tailwheel undercarriage and extensive cabin glazing. Its inverted "V" engine made it resemble its German equivalent, the Fieseler Storch.

United States federal republic in North America

The United States of America (USA), commonly known as the United States or America, is a country composed of 50 states, a federal district, five major self-governing territories, and various possessions. At 3.8 million square miles, the United States is the world's third or fourth largest country by total area and is slightly smaller than the entire continent of Europe's 3.9 million square miles. With a population of over 327 million people, the U.S. is the third most populous country. The capital is Washington, D.C., and the largest city by population is New York City. Forty-eight states and the capital's federal district are contiguous in North America between Canada and Mexico. The State of Alaska is in the northwest corner of North America, bordered by Canada to the east and across the Bering Strait from Russia to the west. The State of Hawaii is an archipelago in the mid-Pacific Ocean. The U.S. territories are scattered about the Pacific Ocean and the Caribbean Sea, stretching across nine official time zones. The extremely diverse geography, climate, and wildlife of the United States make it one of the world's 17 megadiverse countries.

United States Army Land warfare branch of the United States Armed Forces

The United States Army (USA) is the land warfare service branch of the United States Armed Forces. It is one of the seven uniformed services of the United States, and is designated as the Army of the United States in the United States Constitution. As the oldest and most senior branch of the U.S. military in order of precedence, the modern U.S. Army has its roots in the Continental Army, which was formed to fight the American Revolutionary War (1775–1783)—before the United States of America was established as a country. After the Revolutionary War, the Congress of the Confederation created the United States Army on 3 June 1784 to replace the disbanded Continental Army. The United States Army considers itself descended from the Continental Army, and dates its institutional inception from the origin of that armed force in 1775.

Monoplane fixed-wing aircraft with a single main wing plane

A monoplane is a fixed-wing aircraft with a single main wing plane, in contrast to a biplane or other multiplane, each of which has multiple planes.

Three examples were purchased for evaluation against the Stinson YO-49 and Ryan YO-51 Dragonfly. The Stinson won the production contract, and no further YO-50s were built.

General characteristics

Ranger V-770

The Ranger V-770 was an American air-cooled inverted V-12 aero-engine developed by the Ranger Aircraft Engine Division of the Fairchild Engine & Aircraft Corporation in the early 1930s.

V12 engine piston engine with 12 cylinders in vee configuration

A V12 engine is a V engine with 12 cylinders mounted on the crankcase in two banks of six cylinders each, usually but not always at a 60° angle to each other, with all 12 pistons driving a common crankshaft. Since each cylinder bank is essentially a straight-six which is by itself in both primary and secondary balance, a V12 inherits perfect primary and secondary balance no matter which V angle is used, and therefore it needs no balance shafts. A four-stroke 12 cylinder engine has an even firing order if cylinders fire every 60° of crankshaft rotation, so a V12 with cylinder banks at a multiples of 60° will have even firing intervals without using split crankpins. By using split crankpins or ignoring minor vibrations, any V angle is possible. The 180° configuration is usually referred to as a "flat-twelve engine" or a "boxer" although it is in reality a 180° V since the pistons can and normally do use shared crankpins. It may also be written as "V-12", although this is less common.

Stinson 108

The Stinson 108 was a popular general aviation aircraft produced by the Stinson division of the American airplane company Consolidated Vultee, from immediately after World War II to 1950. It was developed from the prewar Model 10A Voyager. Stinson was bought by Piper Aircraft in 1949. All Stinson model 108, 108-1, 108-2, 108-3 and 108-4 aircraft were built by Stinson at Wayne, Michigan. When Stinson sold the type certificate to Piper in 1949, approximately 325 airplanes of the 5,260 model 108s built by Stinson were complete but unsold. These 325 model 108s went to Piper as part of the sale. Piper then sold that inventory as the Piper-Stinson over the next few years.
