Sonex Aircraft announced at a press and customer briefing this morning that orders are now being accepted for the long-anticipated AeroVee Turbo, with deliveries to commence in the fourth quarter of 2014!

The AeroVee Turbo is rated as a 100 horsepower engine at sea level, and yields significant performance enhancement to the Sonex line of aircraft without breaking the bank. Price of the AeroVee Turbo is $10,995, and an AeroVee Turbo Upgrade package is being made available for installation with existing AeroVee Engines, even those already installed and flying, at a price of $3,995.

In a Sonex Aircraft, the AeroVee Turbo will yield a rate of climb up-to 1300 fpm, and a TAS at 8000' of 175 mph. Two Sensenich fixed-pitch propeller options are being offered for AeroVee Turbo installations on Sonex Aircraft. A 54" diameter x 50" pitch prop is intended for those wishing to maximize climb performance while still retaining a very-respectable 170 mph TAS cruise capability at 8,000'. A 56" diameter x 52" pitch prop will maximize top-end speeds, measured as-high as 187 mph TAS using WOT at 8,000' (38 in HG MAP) during Sonex/AeroVee Turbo flight test. Designed with simplicity in-mind, the AeroVee Turbo is intended for use with fixed pitch, or ground-adjustable propellers, keeping the package Sport Pilot Eligible by not requiring a constant-speed propeller, and with sea level cruise just under the Sport Pilot maximum speed at 135mph TAS at the Max. Continuous RPM specification for the AeroVee Turbo under 5,000’ MSL, 3200 RPM.

The AeroVee Turbo is a pull-through turbo arrangement utilizing the standard AeroVee-sized 32mm AeroInjector. As a "free-floating" system, boost is controlled only by throttle setting limited by a fixed waste gate and power still diminishes with gains in altitude, but losses are not nearly as-drastic as those with a normally-aspirated engine. This allows the cruise speed of an AeroVee Turbo in a Sonex Aircraft at-altitude to eclipse the performance of the 120hp Jabiru 3300 engine.

Great Lakes Sonex Fly-In Continues to Grow

"The second annual Great Lakes Sonex Fly-in was another great success," writes event organizer Al Eidukas. This year's 2nd annual event was held on June 28th at Clow International Airport in Bolingbrook, Illinois.

Several informative presentations were made on subjects ranging from avionics & data collection to kit building, to an update on the Sonex Builders and Pilots Foundation from Foundation president Robbie Culver. Eric Seber also gave a presentation regarding his efforts with a youth education Sonex Aircraft project. "Weather was very unpredictable this year with chances of thunderstorms all throughout the day but that didn't stop Bob Meyer, Bill Larson, and his wife Pam from flying in," writes Al. "The group had the opportunity to get up close to check out the planes and talk to Bob and Bill first hand." Door prizes were provided by several vendors, as-well-as the Sonex Foundation and EAA Chapter 461.

"Thank you to EAA Chapter 461 for hosting, Clow Airport's support and the Illinois Aviation Museum for sponsoring this event," remarks Al. "But most of all a Big thank you to all those who attended, because what is a fly in all about - The planes, the people and the conversations." Sonex Aircraft would like to extend a huge Thank You to Al and his helpers for making the Great Lakes Sonex Fly-In a success again in 2014!

Congratulations to Amit Ganjoo of South Riding, Virginia whose Std Gear Sonex (S/N 1470) flew for the first time on June 30th!

Wuzmal flew flawlessly and completely hands off after being trimmed. Thanks to the team at Sonex for creating an excellent design and for providing exceptional plans. All this wouldn't have been possible without my EXTREMELY supportive wife, a very patient EAA Tech counselor Dick Koehler and always helpful fellow sonex builders."

11th Annual NorCal Fly-In Held at Rio Linda!

Sonex Aircraft builders and pilots recently held the 11th Annual Northern California Sonex Fly-In at Rio Linda Airport on May 31st. "Saturday was another fantastic gathering," writes event co-organizer Jeffry Larson. The fly-in attracted 13 Sonex Aircraft and approximately 130 attendees. "This year saw some new, recently completed as well as some of the longtime faithful returning," continued Jeffry. "This year’s arrivals covered a lot of territory, Coeur d’Alene ID, San Diego CA, Los Angeles CA, Livermore CA, Tracy CA, Colusa CA, California Airpark CA, Rio Linda CA, Eugene OR, Lake Oswego OR and Seattle WA just to name a few. Prospective builders also flew in commercially from Canada, Oregon, Nevada, Arizona and Southern CA among a few that I had the opportunity to meet."

Event co-founder and co-organizer Eric Scheppers provided a lunch of BBQ ribs for the large crowd. "Like everything he touches, they couldn’t have been better." writes Jeffry. Several other non-Sonex aircraft arrived at the event, including GA aircraft, RV's and other experimentals, and even several fly-by's by a jet powered Cozy!

As-always Sonex Aircraft would like to extend a huge Thank You to Jeffry Larson, Eric Scheppers, and all other organizers, volunteers and attendees for making this annual Sonex builder tradition a success once again in 2014!

First North Central Sonex Fly-In a GREAT Day!

"The weather on June 7 at Buffalo, MN was CRUD, but the day was GREAT!!!" writes event organizer Wayne Flury about the inaugural North Central Sonex Fly-In held at Buffalo Municipal Airport. "Despite the weather, but recognizing the passion that Sonex pilots have for flying and showing their airplanes, we had two Sonex arrive at Buffalo," continues Wayne. The event attracted a total of 17 current and prospective builders and a great time was had by all.

The day included two formal presentations, one about VW aircraft engines and the other about engine pre-heat systems, round table discussions by all builders in-attendance, door prizes donated by Sonex Aircraft and other vendors, and a fantastic lunch. The event was hosted in the hangar of West Metro Aviation, interesting in it's own right as the home for several airshow aircraft custom builds, including Kyle Franklin's Dracula and John Klatt's Screamin' Sasquatch.

A far more detailed newsletter report of the day's activities can be downloaded in PDF format! "Shall we do this again?" asks Wayne, "Everyone in attendance wanted to see this fly-in event continue, and I think there is a good representation of Sonex projects in the area of justify it." Sonex Aircraft would like to extend a huge Thank You to Wayne Flury, his family and volunteers for making this new grass-roots Sonex builder event a success!

This workshop included attendees from as-far away the Netherlands and Guam!

Mother Nature smiled-down upon Wittman Regional Airport for the weekend, allowing attendees to get the full Workshop experience including factory prototype aircraft fly-by's and many Basic Aircraft Familiarization Flights through our T-Flight Transition Training Program. Part-time T-Flight instructor Tom Helm was on-board this weekend to assist Chief Flight Instructor Joe Norris in making sure that everyone wanting to fly was able to get a flight before the conclusion of the weekend. Workshop attendees also had the whole weekend to inspect every inch of Sonex factory prototype aircraft on the ground, and try them on for size.

The Sonex Aircraft Workshop continues to be an extremely valuable experience for our builders, saving them time, money and answering many frequently asked questions in the building process. Sonex Builder Workshops are held several times per year at the Sonex Aircraft, LLC facilities in Oshkosh, WI, and significant kit discount incentives are offered for attendees. Our next Sonex Workshop will be held October 4-5, 2014. Sign-up Today!
