25 Years Ago in MA:
February 1982

• This month's construction articles are for Frank B. Baker's 58-inch-span RC Northrop P-61 Black Widow, which is extremely flyable with a pair of .10 engines; the Nats-winning Country Boy—an unusual FF model because it has electric power—developed by Bill Jenkins and Jim Clem; and Paul Smith's The Dragon for tearing up the CL Slow Combat competition. It lends itself well to production-line techniques.

• Bob and Dolly Wischer take us on a photo tour of the 9th Annual Greater Chicago Radio Controlled Model Show. D.B. Mathews shows us how to make quick and easy radial engine cowls using foam layered with fiberglass-epoxy. John R. Lange presents a frequency monitor for 4- to 6-meter and 72-75 MHz bands that can be made by anyone who has done some electronics work.

• Jack Finn relates the story of how a team of RC pilots flew a model called "Plenny's Dream" into the world record book by keeping it in the air continuously for 16 hours and 43 minutes.

• Dave Peltz explains how to build a low-cost theodolite to measure the height of sailplanes, and Michael Bame explains the mathematics involved in its use. MA
