Wog (oz2325)

About this Plan

Wog. Free flight gas model. This was a .29 ignition powered class B free flight by William Winter. Appeared in Air Trails, 1945. This plan is the kit version by Megow, kit # E27.

Quote: "WOG (short for Polywog) was designed and built to prove a number of things and to disprove some others. Wog has proved most of the things it was designed to prove. It flies well, has good climb and glide and none of the vicious turn characteristics that lead to spiral power dives, is easily adjusted, and, as the boys on the field say, it is built like a brick outhouse.

It all began with a lunchtime discussion between three of the editors, Walt Schroder, an ex-editor now running his own kit design service, Ed Yulke, and the designer, as to whether, under present Academy of Model Aeronautics rules, power loadings - that is ounces of weight per cubic inch of engine displacement - weren't too low. At a contest the day before, numerous gassies had been observed in wild spiral power dives ending in wood-rending crashes. Too much power, the contestants had said almost to a man. Our discussion turned to ways and means of controlling excessive power. The problems involved proved so interesting that the resulting doodles ultimately led to these plans.

The designer had a soft spot for high aspect ratio wings. Would high aspect ratio control power? And could a high aspect ratio wing - we were talking ratios of ten or more to one - be constructed strong enough to defy a twisting at high speed, despite the fact that the popular NACA 6409 airfoil as used on Wog would be only 5/8 of an inch thick for a 60-inch wing span?

Problem nlumber two I proved to be adjustments. Adjustments can be elaborate and are many and varied. Watt Schroder suggested off-setting the thrust line of the motor to the left and, the same time, giving the ship right rudder..."
