The little engine that could
Revmaster Aviation has finished development of its latest upgraded engine and the results are in: more horsepower at any usable rpm. The new Revmaster R-2300 (2331-cc) engine maintains Revmaster's renowned proprietary systems and parts including its RM-049 heads that feature large fins and hemispherical combustion chambers. It maintains the earlier R-2200 engine's maximum 82 hp at only 2950 rpm continuous, but offers 85 ponies for takeoff at 3350.

LSA Might Not Be the Only Solution to an AWOL Medical Certificate

A year or two before the sport pilot, light-sport aircraft rule became a reality, I wrote an editorial titled "Why Wait for LSA?" Long before the rule became a reality, it was apparent to many that the lack of a medical requirement would mean that those who could no longer pass a third class exam (or never could to begin with) would still be able to legally pilot an aircraft, but they had to wait until the rule was final. Knowing that there was a way to legally fly powered aircraft with minimal training and with a self-endorsed medical, even if a medical was denied, surrendered, or revoked, I wrote the following with the hope that those who had been waiting or had given up could start flying right away. Even though this is an older article, it still applies to anyone who has lost their medical or thinks that sport pilot is the only option.

EAA Promotes Freedom of Aircraft Expression

With the recent news of Burt Rutan retiring in the coming months, Paul looks back to the moment when Burt, his brother, Dick, and Jeana Yeager were the faces of the successful global flight of the Voyager. Burt Joined EAA in 1965 and Paul notes that, over its history, EAA has supported of all phases of aviation. In particular, EAA has promoted the freedom of expression in the design and construction of light aircraft as well as the use of aircraft for personal recreation and transportation.

ELSA or Amateur-Built - Part Deux

Last month's column generated a lot of good conversation and some good questions, so this month I will attempt to clarify a few things and also pass along an update. I'll start with the update. One of the first calls I got when last month's issue of Experimenter went out was from Ken Scott of Van's Aircraft. He called to let me know that my information was already out of date! He was referring specifically to my comment regarding certification of the RV-12 as amateur-built. Ken informed me that Van's had just completed that process and had received the letter from the FAA stating that the RV-12 kit does indeed qualify for amateur-built certification and that it would be added to the list in the near future.

Bass Akwards
Or, Turn the Other Cheek
Ground loop. An ugly word no matter how you define it and perhaps the dominant fear among those without conventional gear time wishing to keep it so. The blame of course is on the single (little) wheel at the rear of the plane not being on the nose. But maybe it’s not the location of the wheel that’s at fault as much as it is the function of the wheel – that being directional control. That begs the question, could a taildragger configuration be tamed if the mains were steerable? Read more

Sloshkosh 2010
As mentioned in previous issues of Experimenter, we're certainly interested in rotary wing articles and will publish them as we receive them. Once again we're treated to an article by Stuart Fields (Stu), editor and co-publisher of Experimental Helo, a bimonthly magazine dedicated to all experimental and personal helicopters. In this issue, Stu recounts his abbreviated visit to EAA AirVenture Oshkosh 2010 with his eye on everything helo. Read more

Hello, my name is Alex Panzera. I'm only 10, and this is my first article. So I'm new to this, but here goes. A month ago, my Papa (the editor of this newsletter), my uncle Tony, and I went to Casa Grande, Arizona, for the COPPERSTATE Fly-In. COPPERSTATE is the fourth largest fly-in in the United States, and the place is completely run by volunteers. Last year was my first visit - it was amazing! But this year I decided to be a volunteer, and I learned it's really important that they have plenty of volunteers there. Read more

Perseverance Pays Off

EAA Staff-built Sonex Makes First Flight 
Sunday, November 28, saw the realization of an eight-year dream at Wittman Regional Airport in Oshkosh as a new airplane, N208GD, taxied out to Runway 22 and took to the skies for the first time. The airplane, an AeroVee-powered Sonex aircraft, is the result of an idea hatched in 2002 that several staff members working at EAA, the cradle of homebuilt aviation, should work together to build an airplane.

With the announcement of the approaching retirement of Burt Rutan, it seemed fitting that this month's Mystery Plane would be one of his lesser-known designs. This petite, single-place, fiberglass "X-Fighter" is the brainchild of Burt, with the collaborative efforts of Gene Sheehan and Tom Jewett. Controversy ensued and was played out in the pages of Sport Aviation as to who should be credited for the design, but ultimately the teamwork of Sheehan and Jewett brought the design to market in the late '70s and early '80s, with the "Outstanding New Design" award won at EAA Oshkosh 1978.

Electric Waiex Achieves First Flight
A proof-of-concept electric-powered Waiex aircraft achieved its first flight today (December 3) at Wittman Regional Airport in Oshkosh, Wisconsin. Piloted by Sonex Founder John Monnett, N270DC made an intentional short hop on Runway 27 to break ground-effect and analyze in-flight system performance as the next step in testing. The uneventful flight was the culmination of four years of development for the Sonex Aircraft, LLC, E-Flight Initiative. Read more

From Light Plane World: Rod Hightower Meets With EAA Ultralight Council
The EAA Ultralight Council headed by Carla Larsh had a full day of meetings on October 30 at the EAA Aviation Center, including almost two hours with EAA President Rod Hightower. Each fall, the council reviews EAA programs and activities that pertain to ultralights and light planes such as EAA AirVenture Oshkosh, ultralight chapters, publications, and government affairs to name just a few. The council members came away from the meeting with the feeling that Rod wants to help us solve some of our biggest problems. Read more | Read November’s Light Plane World

Confused by a strange aeronautical term? EAA's online Aviation Glossary can help.

ROCKWELL SCALE "HRC" - The Rockwell scale is a hardness scale based on the indentation hardness of a material. The Rockwell test determines the hardness by measuring the depth of penetration of an indenter under a large load compared to the penetration made by a preload. There are different scales, which are denoted by a single letter, that use different loads or indenters. The result, which is a dimensionless number, is noted by HRX where X is the scale letter.

There are several alternative scales, the most commonly used being the "B" and "C" scales. Both express hardness as an arbitrary dimensionless number.  More glossary terms

Sport Air Racing League Crowns 2010 Season Champions
There are only a few opportunities for the average aircraft owner to participate in racing his or her own aircraft. The EAA AirVenture Cup provides one such opportunity for experimental-aircraft owners to put their project to the test, but its only once a year. EAA Radio's Fareed Guyot talks with Mike Thompson about the Sport Air Racing League, which since 2006 has been slowly building a year-round racing circuit for both experimental- and production-category aircraft. Listen to the interview

Mystery Plane Air-to-Air
Nathan Peck has known the homebuilt he owns since he was a small boy, when the project was started by his father and a friend. The original builders never finished phase one flight testing, but Nathan eventually did in his senior year in high school. Decades later, through many aviation domicile and career moves, the bird still holds a special place, even with VariEze and GP-4 builds underway. View the gallery (Photos Courtesy: Steve Schulte)
