ultimate RC aircraft, The

Model Airplane News, Mar 2002 by Sharp, Debra

EDITORIAL

A highly evolved relative of our RC models, remotely piloted military aircraft such as the U.S. Air Force Predator are on center stage in Operation Enduring Freedom in Afghanistan, successfully completing their missions while keeping pilots and support troops out of harm's way. Many generations away from the RC target drones of the 1940s, these UAV aircraft are capable not only of sophisticated surveillance but also of firing missiles and destroying targets. Like modelers everywhere, we wondered what it must be like to work with and pilot the ultimate RC aircraft, so senior tech editor Gerry Yarrish decided to find out. In an up-close look at the behind-thescenes operations of the Predator, he shares what he learned from interviews with an Air Force commander in charge of a UAV squadron. In which ways are preparing and flying the Predator like piloting a large RC model? You may be surprised by the answers; check out our inside story on page 28.

Getting the most power, reliability and longevity from our engines is a goal we all share. On page 92, we offer 10 trouble-shooting tips to properly care for and maintain your engine. From using the right glow plug to achieving the best air/fuel mixture to correctly positioning your fuel tank, we show you how to keep your engine performing at peak efficiency.

One of the most interesting components of model airplane design is choosing your construction method. In this month's "Scale Techniques," guest columnist Dick van Mourik discusses various fuselage construction techniques for saving weight while increasing strength. Girder and stick construction, traditional former layout and half-shell building techniques all fit a specific need, and knowing which to use is the first step toward success. Whether you'd like to design a small electric warbird, a .40-size sport flyer, or a giant-scale aerobat, Dick's article will help you more easily choose the construction method that's just right for your project.

And before you start building your model's wings, check out John Tanzer's "how to" on a quick and easy way to make identical shear webs. Add strength to your wing while saving time; see page 106.

Do you like vintage biplanes? This month, we review two classics: a Global Fokker D-VII and a Great Planes Tiger Moth. Easy to assemble, these almost-readyto-fly planes offer gentle performance that complements their good looks.

Our featured construction article is a twin electric, WW 11 warbird designed by Mark Rittinger. A model of an unusual fighter, the Westland Whirlwind has a 42-inch wingspan and uses two Speed 400 motors for power. With a low parts count and traditional balsa construction, this plane will practically fly off your workbench!
