Fly-in Season in Full Swing
By Patrick Panzera, EAA 555743
ppanzera@eaa.org

Pat PanzeraIt’s hardly headline news that there are fly-ins to attend all over the world, but bear with me; I have a point to make. I personally started off this season by hosting CONTACT! Magazine’s Alternative Engine Round-up in Jean, Nevada, at the end of March, with Sun ’n Fun Fly-In at Lakeland, Florida, right on its heels. While at Sun ’n Fun, I was invited to present forums at the Virginia Regional Festival of Flight, an event I had never previously attended. I normally attend the Golden West Regional event in Northern California, but I decided to stay home and fly for International Young Eagles Day.

With three of the four fly-ins outlined above, weather took a serious toll on the attendance, which is understandable since flying (and looking at planes parked outside) is an event best conducted during good weather. In each case, however, as with other such events Ive attended where weather was an issue, everyone still had a great time, and thats my point. We have a lot of other events to look forward to this season, and I would encourage you to consider attending even if the weatherman advises against it. Remember, the promoters, vendors, presenters, and volunteers are dedicated to it, come rain or shine. At the Jean gathering, we probably had 50 pilots (which is a large number for our small get-together) decide to drive to the event since the winds on the ground were crazy and the turbulence aloft was nauseating. As far as I know, no one regretted it, and Im sure that the vast majority had an excellent time. 

My itinerary for the balance of the season includes Arlington, and of course, EAA AirVenture Oshkosh, followed by a number of smaller events such as EAA Chapter Ones open house, a few type gatherings and soaring events, and ending with COPPERSTATE. Although Im obligated to attend most of these events, I wont let the weather interfere with the ones that are optional, unless theyre just too far to drive. I would like to encourage you to do likewise.

Paul's Pick
Paul PobereznyIn May, 1973 Paul Poberezny wrote in Sport Aviation of the benefits of Fly-Ins. He says that events held to bring pilots and aviation enthusiasts are fun, educational, and can make us better pilots. He noted that over 1500 fly-ins, -outs, breakfasts, air shows and the like where held in the U.S. that year. Most importantly he said that these events strengthened the bond of all who were involved in aviation. Even more poetic, he said the "events and activities gave purpose to the airplane."

Tales From the DAR Side
Joe NorrisLittle Things
Attention to detail. That's what it finally comes down to. All the little things that go into building an aircraft are what take up much of the time and effort. But it's those little things that can really set the aircraft apart from the rest, so it pays to spend that time and effort as you work on your project. This month I want to talk a little bit about the nuts and bolts of building an aircraft, as seen through the eyes of the designated airworthiness representative (DAR). The fact is, a lot of the attention to detail I'm referring to is directly related to actual nuts and bolts! Read more

A Modern Classic
Spacewalker II-RR

Aeromorph75Since the beginning of homebuilding, we've had classically lined airframes that begged a round engine, but the smaller scale precluded it since there were no equally small radial engines to be had. A little over 10 years ago, a small Australian company decided to do something about it. Rotec Engineering has paved the way for homebuilders to give older designs a new look.

Since Rotec's introduction, we've seen the Fly Baby, Pober Jr. Ace, Pietenpol, Kitfox, EAA Biplane, and many others benefit from the looks and performance of this attractive round engine. But in virtually every instance, the builder also became the designer, as someone had to be the first to put one of these CNC'd beauties on the deserving airframe. And that's where the amazing creativity comes to play. Martin Hone describes his experience with installing a nine-cylinder, 150 horsepower Rotec radial engine in his Spacewalker II, transforming this already handsome airframe into a timeless, yet modern, classic.

Aeromorph 75
The power behind David Roe's "Diva"
Aeromorph75
In the February issue of Experimenter we reported on David Roe's Hummel Bird and promised that we'd report on the highly modified Volkswagen engine powering it. So in keeping with our promise, we would like to present to you the one-of-a-kind Aeromorph 75 as built by renegade machinist Doug Reid. And before you think this is just another bolt-together VW engine article, consider that the work that went into narrowing this engine to fit the round cowl of David's Hummel Bird produced a four-cylinder VW engine which is taller than it is wide. A destroked crank, custom-shortened connecting rods, and short-skirt BMW pistons are just a few of the components and custom machine work that went into this remarkable engine.

The Ultimate Glue Revisited (Again)
The right wood glue for your wood aircraft
Mick
Mick Myal founded CONTACT! Magazine in 1990, but long before that, he was an active EAA member and regular contributor to EAA publications. For the October 1967 issue of Sport Aviation, Mick wrote a comprehensive four-page article on the use of epoxy for building wooden aircraft. His research article stands the test of time, and a recent letter to the editor (by an EAA member who built two wood aircraft with Mick's recommendations) thanked Mick for his contribution to homebuilding. For those who have never seen the article, Mick has prepared current commentary for its reintroduction. Read more

Rotax 503 Wins ASTM Nod
Kodiak Research Ltd. has announced that following completion of it's testing program, it has determined that the type 503 Rotax engine is ATSM Compliant. The list of ASTM compliant engines, those allowed to be installed in special light sport aircraft (S_LSA), is a short one at best, most being targeted at the 80-120 horsepower range. This leaves the smaller, lighter, potentially ASTM compliant aircraft with few choices. Although the Rotax 583 is the most popular of the engines suited for this type of aircraft, Rotax (BRP-Powertrain GmbH & Co KG ) has succeeded at making their 503 engine ASTM compliant. Read more

Finding a Replacement for AvGas
EAA RadioAviation gasoline, also known as 100LL, has been powering piston aircraft engines since the 1940s. The formulation is so entrenched that several generations of aircraft engines have been designed specifically to perform using this fuel. A combination of impending environmental regulations, shrinking markets, and rising overhead is driving the search for a replacement. EAA Radio's Fareed Guyot talked with EAA Vice President of Government Relations Doug Macnair about a coalition of AvGas stakeholders, including EAA, are doing to find the "new" AvGas.

Flying into AirVenture for the First Time? Watch This Webinar!
An aerial visit to a popular fly-in can be daunting. How about the biggest fly-in at the busiest airport in the world? Any fly-in that publishes an entire book on how to fly to its event can intimidate many flyers. Fred Stadler, who has worked with the FAA for years on the NOTAM book, hopes to make your first visit to AirVenture in an airplane less stressful and safe with this informative webinar. Before flying to AirVenture you should always READ THE NOTAM. We also suggest you watch this webinar too for helpful hints for those who fly-in every year.

Sport Aviation, July 1990 Spacewalker II

What has a tube-and-fabric fuselage, wood-and-fabric cantilever wing, seats two, can be built from plans that costs less than $300 (plus shipping), can use any number of small aircraft engines and automobile conversions for power (85 to 150 hp), and can be built to be flown by a sport pilot? In the July 1990 issue of Sport Aviation, Jack Cox introduces the Spacewalker II, a design that should be considered by anyone looking to build on a budget and fly as a sport pilot. Read the article

Questions and AnswersQ&A
Got a question? Send it to us at Experimenter@eaa.org.
Whether you're building, restoring, or just an enthusiast. we want to know what has you stumped.

Q. I am just beginning to train for my private pilot certificate, with the long-range plan of building and flying my own homebuilt someday. The local flight school has an SLSA that rents for less than their other training aircraft, and it handles more like a homebuilt to boot. Can I take private pilot training in the SLSA?

A. There is nothing in the regulations that would prevent you from receiving training toward a private pilot certificate in the SLSA. However, in order to be able to take all your training in the SLSA it would have to be equipped to perform all the tasks required by the private pilot practical test standards. For example, it would have to be equipped for flight solely by reference to instruments, and for night flight as well unless you want your private certificate to carry a prohibition against flying at night.

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

BLIND RIVET - A hollow rivet, made from any one of a variety of materials, having a shank that is expanded by drawing (or pulling) a mandrel with a head diameter greater than the hole diameter, through the shank toward the head of the rivet. Once sufficient tension is reached, the mandrel is automatically broken off (usually inside the rivet) by the pulling action of the tool designated for the installation of this type of rivet. Developed for use where access to both sides of the working piece is not an option, the blind rivet is designed to be installed from the working side, where the installer is "blind" to the opposite, expanded end.
