What do you do when your horizontal stabilizer isn't exactly horizontal? First, you check that the fuselage is level. If this confirms that the stabilizer is indeed slightly off, remove it and apply heat. Sounds simple, but there's a right and a wrong way to go about it, and author Bob Fritz describes the most effective method to straighten things out.

Builders share their successes.

In our continuing series, author Bob Fritz explains how to use a boring head to drill odd-size or big holes. Hint 1: The bigger the hole, the slower the going. Hint 2: The traveling rest, which moves with the cutting tool, braces the material in two directions to minimize flexing.

You have your off-grid hangar on a solar array, but how to harness its power? Thats what Columnist Jim Weir tackles this month, with an array that tracks the sun to maximum effect.

Columnist Barnaby Wainfan continues his flight-testing discussion by taking up the topic of longitudinal stability. By identifying the origin of the problem, whether it be a control-system issue, a too-small static margin, or a combination of the two, the flight tests he recommends will help to isolate the issue.

Editor-in-Chief Marc Cook discusses the relative merits of internal versus external antennas, after using his Glastar Sportsman 2+2 as a test bed. His conclusions have to do with both the material used to build the airplane as well as location of the antenna on the aircraft.

This months column includes information on new anti-collision strobe lights and LED position lights, a micro belt sander, a smart servo controller for trim, a desktop model of the Cozy Mark IV and the announcement of a taildragger configuration option for the Eurofox SLSA.

When you join two halves of a flat aviation engine together, they often weep between the starter and the alternator. Not only is this unsightly, its wasteful and makes completing an overhaul more cumbersome than need be. Enter Ly-Con, whose groovy O-ring process promises to stop leaks before they start.

With Bose and LightSpeed competing neck and neck (ear to ear?) in the ANR headset arena, author Jack Cowell does a side-by-side comparison to see which model excels.

Motivated by an irresistible bargain and at least a modicum of nostalgia, author Dave Martin recaptures a piece of his earlier flying years when he purchases a twin-engine Lazair ultralight in partnership with two buddies. The Lazair is an unusual design to say the least, and Martin hasnt forgotten how to fly it, so both of his partners will benefit from his experience.
