Sonex Flying Stories - Our New YouTube
Playlist: Mike Kelley Brushes-Off the Winter
Rust with Some Spring Acro!

The number of Sonex customer videos posted to YouTube has exploded over the past few years. As-hard as we try, we just can't keep-up with them all -- which is a beautiful thing to see as the fleet grows! To make it easier for everyone to find Sonex customer videos, we have enhanced our YouTube channel to include a link to the YouTube-generated #SonexAircraft channel, and we have created a new playlist called "Sonex Flying Stories: Our Favorite Customer Videos." Keep sending us those video links that you're especially proud of, and we'll add our favorites to the playlist!

One such video recently came-in from Mike Kelley, builder of Tri-Gear, Jabiru 3300 powered Sonex #1284. For Mike, building an airplane and performing aerobatics in that plane had always been on his bucket list. In summer of 2014, Mike took his first and only aerobatic instruction in a Citabria. "The lesson was taught over the Juan de Fuca straight on a cool day, with a hard 3000' overcast ceiling, not allowing many visual land reference cues," writes Mike. Since then, he has been taking the basic spin, rolls and loops he learned, and putting them into simple +G combinations such as the Spit-s, Immelmann's, wing-overs, and Cuban 8's. He has no intention of ever competing, but enjoys the unencumbered feeling of these sport class maneuvers. "I'd recommend unusual attitude or aerobatics instruction to any pilot," continues Mike, "Practicing these over-and-over, including actually spinning the Sonex, has definitely made me a better & safer pilot. By far, the Sonex was the absolute best kitplane choice for me. Where else could I have this kind of fun and this level of performance on 5-6 GPH!"

Mike's Spring Acro video can be seen below and on our new YouTube custmoer videos playlist along with another recent video of his, "A Day in the Life of Sonex 1284."

Sonex Logs 59th Builder's Workshop Event!

Jeremy Monnett demonstrates the AeroVee powered Onex in a high-speed fly-by for the Workshop crowd on Saturday.

Workshop attendees gained hands-on metalworking experience using Sonex construction techniques with their Workshop projects.

Sonex Aircraft held it's Spring, 2015 Sonex Builder's Workshop on March 7-8, the 59th Workshop event since the company's founding in 1998!

Typical of March Workshops, the event hosted a small, but enthusiastic group of current and prospective Sonex Aircraft builders, as attendees from across the country traveled to Oshkosh to learn more about building, owning and flying Sonex Aircraft. The group constructed sample Sonex metalworking projects, received detailed informational sessions about all Sonex Aircraft designs, engine options, AeroConversions products, and all other aspects of building, owning and flying Sonex Aircraft.

The weather for the weekend gave Northeast Wisconsin a real break, with above-average temperatures in the mid-to-upper 50's! This afforded factory prototype aircraft fly-by's on both Saturday and Sunday, and every Workship attendee seeking a Basic Aircraft Familiarization Flight through our T-Flight Transition Training Program was able to fly -- almost the entire group! 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 May 30-31, 2015. Sign-up Today!

T-Flight Basic Aircraft Familiarization Flights are a popular option for Workshop attendees. Read More about T-Flight Transition Training packages!

Jeremy welcomes the Workshop crowd, lays-out the agenda for the weekend, introduces staff, and passes the microphone around for attendees to introduce themselves.

John Monnett gives a walk-around tour of the technical design features that go-into the Sonex line of aircraft.

John Monnett gives Workshop project demonstrations before turning attendees loose on their own metalworking projects.

Workshop participants get to work on their Sonex metalworking projects!

Jeremy hops into the Waiex for some fly-by's on Sunday morning. In addition to high-speed fly-by's slow flight is also demonstrated, illustrating the impressive performance envelope of Sonex Aircraft.

Sunday is engine day as John educates the group about all things AeroVee and AeroInjector.

John's closing session of aircraft building tips is one of the most informative highlights of the weekend.

Sonex First Flight: Dana Baker

Congratulations to Dana Baker of Acton, California whose AeroVee powered, standard gear Sonex (S/N 1534) flew for the first time on March 8th! "The plane flew great and climbed very well," writes Dana. "I spent an hour getting familiar with the handling in all phases of flight. Many thanks to my wife for understanding my Sonex addiction, all the folks at Sonex and to Gary Aldrich my EAA flight advisor, Steve Irving my EAA Tech Counselor, and the very helpful controllers in the Fox Airfield tower. Now I know what the Sonex grin is all about." Gold Wings are on the way to Dana!

"I purchased the kit from the estate of Russ Woodyard in Tennessee," writes Michael. "My mentors John Gillis and Jeff Shultz said [Russ's project] was a great build, and [that I] just had to finish up the project. Big thanks to my mentors and Steve Rothert for all their help! Can't wait to bring it to KOSH (with paint) of course." Gold Wings are on the way!

First SubSonex Kit Delivered!
New JSX-2 Pilots Minted; Bob Carlton Receives JSX-2 Low-Level Waiver; New Videos Posted!

The first SubSonex Ultra-Quick
Build Kit, ready to ship!

The SubSonex kit fits nicely inside the
optional Triton TC 167 trailer

Sonex Aircraft is excited to report the achievement of several major milestones in the SubSonex Personal Jet program during the month of February: The first SubSonex kit shipped from the Sonex factory; Four new SubSonex model JSX-2 pilots were minted in Moriarty, NM; and Bob Carlton received his Low-Level Statement of Aerobatic Competency (SAC) card for the SubSonex, in-preparation for the 2015 air show season!

First SubSonex Kit Delivered:
On Thursday, February 12th, the first SubSonex kit left Sonex Aircraft headquarters in Oshkosh, destined for customer Redge Greenberg of Durango, Colorado. The Ultra-Quick Build Kit was transported in the optionally available Triton TC 167 enclosed trailer by Sonex staff to Greenberg's home.

This week, two more kits will be delivered to customers in Ontario Canada and Pennsylvania, with kit deliveries to Missouri, Kentucky, and Oklahoma to follow next week. The seventh kit will be delivered to New South Wales, Australia via 20' ocean container. Orders are now being accepted for the second run of SubSonex Quick Build Kit production, to commence in August, 2015.

SubSonex JSX-2 Pilot Population Increases by 400 Percent:
During the weekend of February 1st, four new pilots became qualified to fly SubSonex JSX-2. Sonex Aircraft President John Monnett and Sonex CEO Jeremy Monnett travelled to Moriarty, New Mexico to join Designated Pilot Examiner (DPE) Bob O'Haver and BonusJet flight instructor Billy Hill in making their first flights in SubSonex JSX-2 and subsequent qualifying flights for SubSonex permanent Letters of Authorization (LOA).

On Saturday, all four pilots made their first flights of SubSonex JSX-2, all four with diverse flying backgrounds from highly-experienced jet pilots O'Haver and Hill, to JSX-1 qualified pilot John Monnett, to piston Sonex pilot Jeremy Monnett, who recently completed the BonusJet training program. Remarkably, all four flights looked nearly identical, which is a testament to SubSonex JSX-2's outstanding flying qualities.

Bob Carlton Prepares for 2015 Air Show Season in JSX-2:
Airshow pilot and SubSonex Chief Test Pilot Bob Carlton has been practicing a new air show routine in SubSonex JSX-2 for the 2015 season! Currently booked at EAA AirVenture Oshkosh 2015 and the 2015 Rocky Mountain Air Show with more show dates pending, Carlton has put-together a SubSonex show unparalleled by jet acts of the past including maneuvers such as tail slides (usually taboo in a jet), hammerheads and non-stop action with tight turns inside the typical piston aircraft air show box. Carlton has been practicing the show extensively over the past month, and obtained his Low-Level Statement of Aerobatic Competency (SAC) card for the SubSonex on February 12th in Phoenix, Arizona.

See Today's Press Release!
Much more information about all of the above events can be read in today's official press release.
