When new aircraft from two very different designers, in this case Randy Schlitter and Richard VanGrunsven, surface with considerable similarities, consensus about basic design tenets must be blowing in the wind. Certainly Light Sport regs do constrain performance considerations, but human factors are more up for grabs, and that’s where one or another design can truly shine; by Marc Cook.

Those who plan to build an aircraft from a kit would do well to visit the factory and get to know not only the owners but also the operation. So counsels Editor-in-Chief Marc Cook, whose recent visit to the RANS factory left him favorably impressed. RANS manufacturing is diversified to weather the ups and downs of the market, and the company knows what works and sticks to it.

The Texas Sport Cub’s combination of classic good looks and today’s technology will appeal to those who are looking to rekindle an old flame or those hoping to initiate a new love affair; by Marc Cook.

A recent announcement that a major manufacturer would no longer be making and selling carburetors came as a shock. Although another company has taken up the challenge and will supply carbs, at least for the time being, this news may be the impetus needed to move more aviators toward fuel-injected power for their homebuilt aircraft.

Ten years of meticulous workmanship and a daughters dedication combined to result in a stellar example of a Sequoia Falco F.8L. Builder John Shipler enjoyed the fruits of his labor before his health declined, and his daughter Kris has continued to fly and maintain the airplane after his passing.

Editor-in-Chief Marc Cook highlights an intriguing product that caught his eye at AirVenture Oshkosh 2007, and he reiterates the difficulty of bringing new engines to market.

While new electronic flight instrument systems (EFISes) sometimes seem ubiquitous, PC Avionics new yourGlassPanel line stands out as an easily retrofittable blend of form and function that may fit the bill for homebuilders seeking a moderately priced primary or backup EFIS; by Marc Cook.

Marc Cook reviews the new twin-turbo Velocity TXL from Velocity Aircraft. Among the benefits of the new configuration, which includes two Garrett turbochargers on the Continental engine, is power that keeps performance consistent well into higher altitudes-to the tune of 250 knots at FL250.

Editor-in-Chief Marc Cook weighs the relative merits of perfectionism in building and maintaining homebuilts versus using the aircraft for its intended purpose: flying.
