Flight Reports Turbine Moose: The Ultimate Amphib It’s said that sailors make good floatplane pilots because they understand the nature of wind on the water. Sailboat racer and pilot Rick Orchard took that sentiment to heart in a big way when he decided to pump up an already large homebuilt (the Murphy Moose) by adding Aerocet amphibious floats and a 550-horsepower Pratt & Whitney PT6A-20 turbine engine. The Staaken Z-21A Flitzer Intended as an inter-war sportplane, the VW- or Jabiru-powered Staaken Flitzer delivers the goods in both performance and agility. These planes may not appear sleek, but they’re a blast to fly. Builder Spotlight Build Your Skills: Fabric Who knew there was so much to consider when selecting a fabric for your aircraft project? Cotton or polyester? Light weight or heavy? STCs, TSOs, PMAs, FAA requirements. Poly-Fiber or Ceconite systems? Ron Alexander unravels the alphabet soup and explains how and why each fabric may be the way to go for a specific project. All About Avionics Much of our focus in this series has been on the latest and greatest electronic gadgetry. But traditional instrument packages, the so-called “six-pack,” have their benefits. Avionics wizard Stein Bruch extols their virtues and explains their vices in this month’s installment. Found From Space A technology developed by ham radio operators, called automatic position reporting system (APRS), coupled with low-cost GPS receivers, a decent antenna and the World Wide Web, have made it possible to track light-aircraft flights without incurring access or subscription fees. Yes, you’ll need to get a Technician license for radio operators, but that’s a minor obstacle if this system is something you want or need to use. Continental Pushrod Tube Modification Owners of a certain type of Continental engine, the cam-at-the-bottom variety, are undoubtedly familiar with the annoying seepage of oil from swaged pushrod tubes and rubber pushrod seals. Now there’s a cure, and author Ron Darcey describes the fix. Completions Builders share their successes. Shop Talk Setting Up Shop Before you decide you can’t build a plane because you don’t have enough shop space, think again. After all, as author Bob Fritz points out, projects have been built in apartments. This article won’t go quite that far, but it does detail some pitfalls to avoid and makes suggestions about maximizing the ease and efficiency of working in a limited-space environment. Aero 'Lectrics Using LEDs for lighting an aircraft has much to commend it. Low draw, reasonable cost, long life, good visibility. This month, Jim Weir takes us through the beginning steps of building these lighting systems yourself, using off-the-shelf parts and a little ingenuity. Designer's Notebook Wind Tunnel Pitch is not the only axis involved in making an airplane fly well. Yaw and roll are also important, and this month Barnaby Wainfan turns his attention to lateral/directional stability and its effect on flying qualities. Exploring Around the Patch Velocity Aircraft has been acquired by Rocket Racing Group, and Editor-in-Chief Marc Cook discusses the implications for the company specifically and the industry in general. Also, Dick Starks has a new book out that regales readers with tales of his wacky Dawn Patrol adventures. What's New The first diesel-powered LSA debuts from IndUS Aviation, Stafford Manufacturing offers a variety of mounting collars, and AirGator improves its handheld electronic flight book (EFB). Fire in the Hole We’re all used to the standard red canister fire extinguisher, often encased behind glass, that we’ve grown up with at school, work and at home. But the need to put out flames in racecars has brought about a new generation of extinguishers, suitable for aircraft, which offers effective protection in a small and attractive package. Dan's World Columnist Dan Checkoway appreciates the flexibility of owning a homebuilt rather than a certified aircraft. On a recent condition inspection of his RV-7, he detected small cracks in the front spar of the horizontal stabilizer. A week later he was working on replacing it, without any intervention from the FAA. Light Stuff Dave Martin introduces us to the Gobosh factory-built Light Sport Aircraft (SLSA) from Poland. Positioned at the luxury end of the LSA spectrum, there are two models: the all-metal G700S and the composite G800 XP, each of which includes standard six-pack instrumentation and leather seats.
