Cool Runnings
Norm Ellis does the math and shows you how to select the right oil cooler for your engine-cooling package. Given the critical role oil temperature plays in engine health, its a good idea to go beyond selecting the smallest, lightest and cheapest cooler you can find.
To Launch a Light Sport
Bob Fritz presses on! In this installment, he powers up the Grand Rapids Technologies EFIS panel, solves a curious com antenna problem, installs the Zaon PCAS, fits the door to the fuselage’s curvature, and streamlines the air flow to the oil cooler.
Aero ‘lectrics
Jim Weir continues his series on digital logic (CMOS), and makes the little logic circuits do things that their inventors never considered.
Wind Tunnel
Accelerate, pull and fly-thats not all there is to the takeoff. Barnaby Wainfan takes a second-by-second look at the aerodynamics of the takeoff: when it works, and when it doesn't.
The Home Machinist
Phillips? Flat head? Double blade? Bob Fritz clears up questions you didn't even know you had about screwdrivers. When you're building a plane, the right tool for the right job (and right space) really does matter.
Cable-Exit Fairings
Don't let unsightly cable-exit holes spoil the look or performance of your aircraft.
All About Avionics: Autopilots
Want to be fresh at the end of a long flight? Experimental-only autopilots beat their certified counterparts. They're usually less expensive, more capable and far more user-serviceable (if you know what you're doing). By Stein Bruch.
X Marks the Spot
Light and slow, yet lacking control skittishness, the X-Air is a simple and fun way to go nowhere in particular. By Bob Grimstead.
Industry Report: What’s Up With LSAs?
Four years after SLSAs were approved by the FAA, dozens of companies producing more than 100 aircraft models have qualified as SLSAs. Dave Martin examines the state of the industry in light of the current economic climate.
In Case You Missed It
Something Wild
When a homebuilder has a vision for a unique paint scheme on his RV-3, he assembles a team that can bring it to life.
Firewall Forward: Engine Mounts
Dynafocal, conical or DIY? Some engine-mount decisions are dictated by your choice of engine, but there’s more to it than that. Dave Prizio walks you through the process of mating engine to airframe.
Flying in the Ford World
Sage philosopher and aviation nut Uncle Ishmael explains how, for about the price of a 4-year-old Ford pickup truck, you can own a serviceable homebuilt aircraft. Youll probably have to forgo anything certified, and hone your scrounging skills, but when all is said and done, isn't getting up in the air flying better than sitting on the ground dreaming?
