Cover Story
Few homebuilders forget the first airplane they constructed, even if they go on to do others. That was the case with Mike Maxwell, who had pretty much given up on ever seeing his Lancair 235 again. But life is nothing if not full of surprises, and Mike was in for a big one.

Few homebuilders forget the first airplane they constructed, even if they go on to do others. That was the case with Mike Maxwell, who had pretty much given up on ever seeing his Lancair 235 again. But life is nothing if not full of surprises, and Mike was in for a big one.
Enchanted with the idea of building his own amphibian, Larry Woods came across a Ukrainian design, the Aeroprakt A-24, which seemed to fit the bill. After much research, he got a hold of a kit, built it, and then liked it so much that he became the Canadian distributor.
Fabric has been used to cover a wide variety of aircraft since the Wright brothers first started tinkering with flying machines. But fabric-covering processes have changed a lot in the last century, becoming more systematic in addition to being more reliable. Part 1 of this new series by Ron Alexander details the evolution of fabric covering and discusses some of the basics of getting started.
Today’s homebuilt aircraft avionics packages often incorporate a number of boxes behind the panel, all requiring a particular type of wiring to go with them (not to mention all the other power draws such as lights, flap motors, etc.). It’s advisable, then, to consider the length and nature of the wiring to be included in your project from the moment you start building. Avionics techno Stein Bruch explains the how and why of managing the wiring requirements for your aircraft.
If you always wanted a custom exhaust for your homebuilt but were too afraid to ask, consider this alternative where you build the model and then send it in to the shop for professional fabrication. Author Bret Davenport found the Aircraft Exhaust four-into-one collector system for his Pitts S-1S more than satisfactory.
The Scratch-Building Alternative
Mark Townsend’s scratch-building seminar allows builders to come away with the hands-on experience and the confidence they’ll need to start building a kit aircraft such as the Zenith STOL CH 701 from plans.
Builders share their successes.
Shop Talk
What do you do if you want to cut a longer-than-usual taper? Well, first you’ll need to create a simple tool from some round stock that will provide target zones for your dial indicator, and then you may need to buy some more tools—what a shame! Home Machinist Bob Fritz takes you through the process. Hint: Choosing the right Morse Taper is critical.
If you've ever wondered who invented the ubiquitous light-emitting diode, wonder no more. Columnist Jim Weir explains the origin and evolution of LEDs, and how to wire them up for use in your aircraft.
Designer's Notebook
When is an airplane in trim? At least to the pilot, the airplane is trimmed when no stick force is required to maintain equilibrium. So how do we achieve this? Barnaby Wainfan explains any number of ways to go about it, including the use of trimtabs, spring systems, sparrow strainers and variable incidence tails.
Exploring
Have you checked your fuel system for leaks lately? Turns out there’s a good reason to periodically conduct a thorough investigation. Incipient leaks may go undetected. Worse, when the O-ring on the fuel-selector valve goes bad, it could allow air into the system, which means your engine could misbehave at a most inconvenient time. Often, this malady is difficult to diagnose and the assumption is that the fuel selector is OK when it is not.
The new Lancair Evolution flies, and the Aircraft Electronics Association speaks out on ADS-B implementation. The Arlington Fly-In and EAA sign new agreement, and Garmin introduces the GPSMAP 495. Aircrafters LLC is the distributor for a new overhead lighting console.
You’ve invested thousands of hours building your airplane, and now it’s time to pick a paint design that will show off all that hard work to best effect. But how do you go about selecting one of innumerable designs? Susan Brunner offers some tips on not only how to narrow the field, but also how to make sure you get the paint job you envisioned.
When it came to choosing a kit aircraft to build, columnist Amy Laboda and her husband opted for a metal design, in part because it would be resistant to destruction by lightning strike and also because fatigue is easier to detect in metal than it is in a composite plane. However, new nanotube technology, if integrated into composite construction material, could not only help identify wear problems, but also potentially “heal” them.
Here’s one instance where the sound of silence (as in no engine noise) won’t signal the need to start scoping out a place to set down. The Urban Air motorglider offers a compromise that makes the best of both worlds: fuel-efficient powered cruising and exciting powered-off soaring.
