A walkalong glider is a lightweight, slow-flying model aircraft designed to be kept aloft by controllable slope soaring in the rising air generated by the pilot who walks along with the glider as it flies, usually holding a paddle. Hands or even the forehead can also be used to create an updraft.
Originally the model was used as a hands-on activity for museum visitors and museum outreach. In 2004, the AMA incorporated the model into Aerolab, an instructional program developed for middle school physical science and math programs, that uses simple flying model aircraft as tools to teach Force and Motion .
The Wedell-Williams Model 22 was a racing aircraft, two examples of which were built in the United States in the early 1930s by the Wedell-Williams Air Service Corporation. It was one of three early projects by aircraft designer Jimmy Wedell to create a racer and was built specifically to compete in the 1930 All-American Flying Derby from ...
The Wedell-Williams Model 44 is a racing aircraft, four examples of which were built in the United States in the early 1930s by the Wedell-Williams Air Service Corporation. It began as a rebuilding of the partnership's successful We-Will 1929 racer, but soon turned into a completely new racing monoplane aircraft, powered by a large radial engine .
In the 1950s and 1960s until recently, Cox has produced a line of hobby-oriented models of cars, airplanes, and other vehicles. The most noted are the .049 cubic-inch displacement glow fuel powered models, controlled by line (Control Line) or by radio (Radio Control). AMC Matador.049 engine police car from the TV series Adam-12; T-28 Trojan ...
After the death of Williams, the Model 45 was donated to Louisiana State University, where it eventually disappeared, its final fate unknown. [2] A full-scale replica Model 45, constructed by Jim B. Clevenger of Kissimmee, Florida, is on display at the Wedell-Williams Aviation & Cypress Sawmill Museum in Patterson, Louisiana. [2]
Non-planar wingtips are normally angled upwards in a polyhedral wing configuration, increasing the local dihedral near the wing tip, with polyhedral wing designs themselves having been popular on free-flight model aircraft designs for decades. Non-planar wingtips provide the wake control benefit of winglets, with less parasitic drag penalty, if ...
Early versions merely constrained the model to fly in a circle but offered no control. This is known as round-the-pole flying.The origins of control-line flight are obscure, but the first person to use a recognizable system that manipulated the control surfaces on the model is generally considered to be Oba St. Clair, in June 1936, near Gresham, Oregon.
