Twin Midget Mustangs at AirVenture 2011
Twin Midget Mustangs

Looking at these two beautiful experimental airplanes being wiped down by their owners in the early evening after a long day at EAA AirVenture Oshkosh, Experimenter Editor Pat Panzera states, "I had to rub my eyes to make sure I wasn't seeing double." These two planes are stunning examples of attention to detail and have been built by the father and son team of John and Brad Errington. These two builders meticulously constructed textbook-perfect versions of the Midget Mustang, the predecessor to the ever-popular Mustang II. Although identical in virtually every aspect, Brad needed to one-up his father and opted to install a modified O-200, besting dad by 15 mph. Read more

AirVenture Wrap-Up

The 2011 annual EAA convention, also known as EAA AirVenture, Oshkosh - The World's Greatest Aviation Celebration, was the most exciting I've ever attended. This may not be saying much since I've only been attending for the past decade, but from what I've been told, there were 976 homebuilts present, just a few shy of the all time record. I don't think we ever cracked 1,000 yet, but we came real close. As promised in my wrap-up featured on the AirVenture website, the following is my full report on AirVenture 2011.

Doug Rolfe and His JN-D-4
As told to Paul Poberezny

The name Douglas Rolfe is synonymous with excellent aircraft drawings, and those of us who have followed aviation through the years have recognized his drawings whether they're in the old Flying Manuals - past and pre-'30s, or in Air Progress magazine - past and pre-'98. Many of us will find it interesting to know that Doug started his aviation career at an early age while living in Europe, but it's best to let him tell his story.

Uncensored, Raw, Fun Homebuilding
Brady and Caleb are first-time homebuilders who are scratchbuilding an airplane, a Bearhawk to be exact, in Caleb's basement. They stream live video every week and welcome you to watch as they build their very own flying machine. Their build sessions, most Tuesdays at 6:30 p.m. (Central), are uncensored, raw, fun homebuilding - one rib, flange, and lightening hole at a time. Watch the video

Winter Work - Part Deux
Joe Horton checks in
In the March 2010 issue of Experimenter, EAA member Joe Horton of Coopersburg, Pennsylvania, told us a little about the work he performed on his KR-2S over the 2009/2010 winter, some being upgrades, some being repairs. This past winter he was determined not to go through that again, but rather he wanted to fly. 

Winter work
To his dismay, Mother Nature had a different idea, throwing a serious winter all over the Northeast. Taking advantage of his downtime, Joe made some new changes to his plane. Read more

This design has been around for more than 50 years. It's been through many design changes and includes several options. It can be built with conventional or tricycle landing gear. It was introduced as a single-seat design that later evolved into a two-place by widening the fuselage to fit the occupants next to one another. Read more

Hummel UltraCruiser Serial No. 1 Flown to AirVenture from New York
The original prototype all-metal UltraCruiser ultralight designed, built, and flown by Morry Hummel was flown to AirVenture from central New York state by its new owner Kirk Mills. It was his first long cross-country flight. The engine is a two-cylinder 1/2 Volkswagen that gives the FAR 103 legal ultralight a range of nearly 150 miles. He had planned to have some flying companions but ended up going solo. Read more

Inside the Pipistrel Taurus 4
Experimenter Editor Pat Panzera was at the right place at the right time, specifically the day before EAA AirVenture Oshkosh when the engineers and mechanics were putting together the electric-powered Pipistrel Taurus 4, and he got to see what's in that huge nacelle. Read more | First Flight

Maiden Flight for SubSonex
Sonex pleased with test program progress
A little yellow jet was spotted over Oshkosh recently and soon it was confirmed that John Monnett's SubSonex had made its first flight. Jet sailplane pilot Bob Carlton, who wowed AirVenture crowds last month, has now made at least five flights and according to Sonex the company is "quite pleased" with how it's flying. The flights are the culmination of at least four years of development including an engine change and a design review to address controllability during takeoff and landing. 
The initial flight was a happy day for Sonex Founder John Monnett, who designed the SubSonex for the recreational pilot. Read more and watch the videos

The Robinson Seabee Conversion
Do automobile engine conversions used to power otherwise obsolete certificated aircraft sound like a viable powerplant answer to you? It certainly does to Brian Robinson who has brought the Republic Seabee into the present century. He and three other Seabee owners, who have his conversion, flew into EAA AirVenture Oshkosh 2011.

The Source of the McCulloch Engine
Many may have seen the little four- and six-cylinder two-stroke, horizontally opposed, compact target drone engines built by McCulloch, but not many have seen the drone. Experimenter Editor Pat Panzera found one at EAA AirVenture Oshkosh. Read more

EAA Members Respond to EAA/NTSB Amateur-Built Safety Study
5,000 completed - survey closes August 31

EAA has been working with the National Transportation Safety Board (NTSB) to create a profile of amateur-built aircraft and their builders to use as a guide for programs and activities to further advance and promote safe building and flying practices. EAA is hosting the summer-long survey that is open to all builders, owners, and operators of experimental/amateur-built category aircraft. According to Jim Sweeney, EAA's director of market research, the response to date has been outstanding with more than 5,000 surveys completed.

Chris Heintz Honored at AirVenture Dinner
On Wednesday evening at AirVenture, aircraft designer Chris Heintz was greeted by nearly 250 attendees who gathered together for a dinner in his honor. Hosted by Sebastien Heintz, Chris' son and president of Zenith Aircraft Company of Mexico, Missouri, and Charlie Becker, director of EAA Member Programs, attendees came from as far away as Venezuela and South Africa. Paul Poberezny was the guest speaker and gave the message that we are all family, which is especially relevant to the Heintz family of five sons who are all in the process of following in their father's footsteps.

Eye of the Experimenter: Not all canards are Rutan canards
…but they're all inspired by him

It's nice to see so many canards at this year's AirVenture. By Wednesday morning, the count of all Rutan-designed (or -inspired) aircraft on the field was approaching 200. But to the casual observer, any or all of the canard aircraft on the field seem to have a common source, that being the fertile mind of Burt Rutan. It's a logical assumption since Burt was the seemingly the first EAAer to arrive at AirVenture with this unique canard design, the VariViggen, named after the Swedish fighter plane, the Saab 37 Viggen.

EAA SportAir Workshops

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

CANARD - An arrangement in which the horizontal stabilizer and elevators of an aircraft are mounted in front of the wing(s). An airframe configuration of fixed-wing aircraft in which the forward surface is smaller than the rearward, the former being known as the "canard," while the latter is the wing. In contrast, conventional aircraft have a small horizontal stabilizer behind the wing.

A Fast Long-EZ
Gary and Char Spencer's Long-EZ, powered by a direct-drive, all-aluminum small-block Ford 302, bored and stroked to 360 cubic inches, is capable of 250 mph with better fuel economy than an O-235 when flown at the same speed. Watch the video

Fournier Glider Lets Fresh Air In
This is possibly the first Fournier RF5B in the U.S. that can be flow sans-canopy. The canopies can be exchanged for the fresh-air configuration in about three minutes, allowing you to choose the kind of flying you want to do on any particular day. If you want to know more, read our two-part article on the Fournier RF4D Motorglider from last spring.

Timeless Voices of Aviation: John McGinnis
John McGinnis is the brainchild behind the radical new aircraft design called Synergy, a competitor in the CAFE Foundation's 2011 Green Flight Challenge. Inspired by Burt Rutan, John decided to design his own airplane. Life got in the way, but the dream never died, and over the past 35 years John researched as much as he could about aerodynamics and drag. His "eureka" moment came after reading a paper on viscous induced drag by George Green of NASA Langley. Everything John has learned has come together in the Synergy design and he shared the story of its development during AirVenture 2011. Watch the video
