Before you think to yourself, "I couldn't afford that, let alone fly it" relax a little and let your imagination run wild. The ViperJet offers glove leather interior, rosewood inlay, and performance to spare. Doug Rozendaal completes the picture.

Changing with the times, Zenith Aircraft has introduced an improved version of a design that debuted some 20 years ago. With a larger payload, more robust landing gear and greater visibility among other features, the CH 750 is tailored for today’s sport pilot;

A New Name on the Alternative Engine Block

When NSI went under in 2005, builders who had an engine or were waiting on parts for one might have found themselves in a world of hurt. But seeing an opportunity, John and Gwen Maxwell acquired the assets of the company and have endeavored since to make a sound product even better; by Marc Cook.

Although the KK-1 is scratch-built, builders Ken Scott and Ken Krueger have used all of the modern tools at their disposal to expedite the design and building process. This month, Scott discusses the more than satisfactory results of load-testing the wing and horizontal stab;

Lancair Evolution

0
When Joe Bartels bought the company from founder Lance Neibauer in 2003, he knew it was time for a change. The goal was to find a high-performance aircraft that could be flown by the average pilot in the target market. The solution can be found in the company's newest product, the Pratt & Whitney-powered turbine Evolution; by Doug Rozendaal.

Van’s RV-12

0
In typical fashion, Van’s Aircraft refused to rest on its laurels after the RV-12’s 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.
