Van’s RV-12

0
In typical fashion, Vans Aircraft refused to rest on its laurels after the RV-12s prototype debut last year, and sought to improve on an already good design. The new production airplane has changed (beyond its color), with a castering nosewheel, toe brakes instead of a grip, reshaped control sticks for better clearance, ground-adjustable seats fore and aft as well as in tilt, and the list goes on. Best of all, this day/VFR machine is still a delight to fly; by Ed Kolano.

Lancair ES-P

0
Robert Simon had the distinction of building the first Lancair ES-P to fly. But the process wasn’t without its challenges. The ES-P employs the cabin design and structure of the pressurized, retractable Lancair IV-P, but has a larger wing and fixed gear. During the build, Simon also deviated from the base design with changes that required factory support to accomplish. Not only did he learn much, he ultimately got the plane he needed; by Dave Higdon.

Around the Patch

Homebuilt aircraft manufacturers are sometimes reluctant to admit that they have created a less than perfect design, let alone offer a fix. Arion Aircrafts Nick Otterback is bucking that tide; by Marc Cook.

Down to Earth

A month after the engine was first started on the RV-10, author Amy Laboda and her husband, Barry Marz, scheduled a visit from DAR Ray Howell, received the airworthiness certificate, and commenced ground runs. It sounds simple, but so much effort went into getting that little piece of paper.

Light Stuff

As Light Sport Aircraft become more popular, so too will the desire to learn more about maintaining one of the most common engines used in these designs, the Rotax four-strokes. Columnist Dave Martin goes back to school to learn about routine Rotax maintenance as well as safe operation of the popular engine.

This month, fabric expert Ron Alexander discusses attaching the fabric to the aircraft parts using either a pre-sewn envelope or individually cut pieces of fabric. The process is optimized for strength in flight as well as aesthetic appeal.
