Fourth Customer-Built SubSonex Personal Jet Makes First Flight: John Corneal

SubSonex Personal Jet customer completions are continuing to roll-in with a high success rate, as another customer-built SubSonex has flown! Congratulations to John Corneal of Petersburg, Pennsylvania whose SubSonex SN#6 flew for the first time on April 20th!

"N465JC took to the sky for her maiden flight this afternoon at 4pm," writes John. "The flight lasted 40 minutes. The flight consisted of 10, 20, & 30 degree banks, slow flight in both clean and landing configuration, climbs and descents, and a simulated go around, followed by a return to the airport for a go around and landing. The plane handled flawlessly and was a joy to fly... Thank you for a wonderful design." Gold Wings are on the way to John!

Second Customer-Built SubSonex Personal Jet Makes First Flight: Andrew San Marco

Another customer-built SubSonex Personal Jet has flown! Congratulations to Andrew San Marco of Fairfield, Connecticut whose SubSonex SN#7 flew for the first time on December 2nd! Andrew writes:

"On Friday December 2nd, N13MB flew for the very first time.With Bob O’Haver at the controls, he departed New London, Ct, (GON) at 7:45 am. The initial flight was just over 30 minutes. Bob conducted some stalls, and slow flight followed by a low approach over the field. Shortly after 9:30am, and a pre flight briefing, I jumped in for a 35 minute flight over the Long Island Sound. The plane flew flawlessly, and handled far greater than I could have expected. The handling characteristics were smooth. Landing the plane was much easier than I had anticipated. With power at 88% at 5500 feet, I was seeing speeds at 210MPH. What a fantastic machine.

I wanted to take the opportunity to thank all of the folks at Sonex, with special mention to Kerry, Levi, and Joe. I’m grateful for your patience and support. I also want to thank Bob Carlton, Bill Hill, and Bob O’Haver for their wisdom and attention to detail during the LOA training In New Mexico. The training makes for a great transition into this aircraft. Finally, to the team in Groton, Chris Bergman, Tim Pavkov, and Gerry Sykes, you guys did an amazing job, I thank you for your guidance and amazing talent in making this a reality.

I look forward to enjoying this aircraft for years to come."

Gold Wings are on the way to Andrew!

SubSonex First Flight: Redge Greenberg
Flies First Customer-Built SubSonex!

Redge Greenberg with build partner Dwight Tolfer and SubSonex S/N JSX0003.

Redge gives a "thumbs-up" in the cockpit of his SubSonex!

Congratulations to Redge Greenberg of Durango, Colorado, who made the first flight of SubSonex serial number JSX0003 yesterday, October 15th: the first customer-built SubSonex Personal Jet to fly! "I flew the SubSonex this morning, for about 35 minutes… all went well," writes Redge. "My regards to Dwight Tolfer who was a big help for me during the construction project that was done almost entirely in my garage."

Redge received the first SubSonex kit delivery in February, 2015, an Ultra-Quick-Build kit with optional Triton Trailer (see our February 16th Press Release). The SubSonex is sold as a Quick Build Kit only, leaving very little work for the customer, and providing almost everything needed to fly with the exception of avionics and paint! Two Quick Build Kit versions are offered: an EAB-compliant kit for the traditional builder including pre-built wings, fuselage and canopy; and an Experimental Exhibition category Ultra- Quick Build Kit with no “51 percent rule” restrictions.The Ultra-Quick Build customer will install the easily-removable outboard wing panels, engine and fuel system, bolt-in the retractable landing gear, install avionics, electrical systems and controls, install the supplied BRS, fiberglass components and upholstery, and add paint.

"I hold commercial glider, helicopter & single engine land licenses, accumulating 4500+ hours in numerous aircraft," wrote Greenberg for our February press release, "but I never got the chance to fly a jet. I first saw the prototype of the SubSonex at Oshkosh, and followed the development for over a year. When Sonex offered the jet as a kit, I was first in line. Like my RV8, the SubSonex is aerobatic, but the Sonex company also included a ballistic parachute for extra safety."

With two SubSonex JSX-2 factory prototype aircraft now flying, Redge's SubSonex makes number 3 in the worldwide fleet, with 6 more customer kits currently under construction.

Gold Wings are on the way to Redge!

JSX-2 Fleet Doubles: SubSonex N241SJ Flies!


The skies over Oshkosh were once again filled with tiny jet noise this afternoon as the JSX-2 worldwide fleet doubled with first flight of SubSonex N241SJ! John Monnett took the sister ship of #1 JSX-2 prototype N141SJ for a short flight today, which was uneventful and successful. #2 JSX-2 N241SJ was constructed at the same time as N141SJ, but flying the aircraft took a back seat to flying and refining it's "Sonex yellow" sibling, leading to it's use advertising the design as Bob Carlton's airshow bird. The gray, shark-mouthed JSX-2 #2 will serve as Sonex's Oshkosh-based SubSonex factory demonstrator, and incorporates all the latest refinements to the SubSonex design.

New DVD! "SubSonex: Flying JSX-2"

We are excited to announce that an all-new SubSonex DVD will be released at AirVenture 2015, featuring the past year's flight footage of JSX-2! "SubSonex: Flying JSX-2" includes much of the footage recorded and posted to our YouTube channel since the new jet's first flight 1 year ago.

SubSonex Microjet Makes Kitplanes and AOPA Pilot Covers; Bob Carlton Wins Bill Barber Award!

The SubSonex JSX-2 microjet will be hitting mailboxes this month on the covers of AOPA Pilot and Kitplanes magazines!

"SubSonex: The practical jet age arrives" is an expansive 19 page feature story in the August issue of Kitplanes magazine, (download 3.7mb PDF file) written by the magazine's editor-in-chief, Paul Dye. Paul is the first non-Sonex pilot to fly the SubSonex, and his article is a very favorable flight review of the aircraft, which includes sidebar articles about the PBS TJ-100 turbojet engine, an interview with John and Jeremy Monnett, a description of SubSonex kit contents and pricing, the SubSonex transition training process and the transition training aircraft: the TsT-14 BonusJet. A video was released in May about the SubSonex and Paul Dye's experience flying the aircraft, which is available on YouTube.

"Having A Blast: A glider transition to a jet" is featured as the July 2015 cover story in AOPA Pilot magazine, (download 3.2mb PDF file) written by editor Dave Hirschman. Hirschman was the second non-Sonex pilot to fly the aircraft, and he was very complimentary of the SubSonex in the magazine's "Hangar Talk" section: "Flying JSX-2 is a scream," he says. "It's intoxicating, and it's easy to imagine flying clubs and partnerships being formed around this exciting new aircraft." The 8-page feature article thoroughly reviews the SubSonex and also covers the TsT-14 BonusJet transition training process. AOPA also released a great video about the Subsonex and Dave Hirschman's experiences flying the aircraft!

Transition training is a significant milestone associated with these two articles, as Desert Aerospace's BonusJet program allowed both pilot journalists to gain their FAA LOA's (Letter Of Authorization) to fly the SubSonex via the same mechanism that SubSonex customers will use to transition into their SubSonex kits. Both Paul Dye and Dave Hirschman came-in to the program with similar sport aircraft experience, and both completed the program successfully. Watch our Webinar about SubSonex Transition Training!

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.

New Videos!
Four exciting new SubSonex videos were also released today on the Sonex Aircraft YouTube Channel:

SubSonex Update: FAA NKET Checklist Posted, SubSonex Gets New Gear and New Test Flight Video Footage is Available!

The three months since AirVenture Oshkosh 2014 has seen tremendous progress in the development and production of the SubSonex Personal Jet! SubSonex EAB Quick Build and SubSonex Ultra Quick Build kit production is well underway for our inaugural group of customers, and all of those customers have visited us here in Oshkosh since the first flight of JSX-2 to see more of the aircraft. The mutual excitement between Sonex personnel and this special group of customers is contagious as the project continues to develop!

FAA NKET Checklist Published
The FAA National Kit Evaluation Team (NKET) visited Sonex Aircraft once again in late August, this time with the task of auditing the SubSonex EAB Quick Build Kit for compliance with the "major portion" requirement of 14 CFR section 21.191(g) for experimental/amateur-built aircraft, commonly referred to as the "51 Percent Rule." The SubSonex checklist created during that visit was approved on September 15th and posted recently to the FAA's web site listing of audited kits. More information and links to the FAA NKET documents can be found on our Aircraft Certification web page.

SubSonex Gets New Landing Gear
Unsatisfied with the level of reliability and possible failure modes of JSX-2's original electric actuator landing gear system, the SubSonex development team began work immediately after AirVenture to convert the aircraft to a pneumatic landing gear system. The pneumatic actuators are simpler and more reliable with a longer service life, are available at lower cost, feature a simple and more reliable gear position indication system using hall effect sensors, and have a safer failure mode than the original electric gear -- loss of air pressure in the system causes the gear to deploy and lock due to gravity. A demonstration video of JSX-2's new air-driven landing gear system can be found on YouTube!

Another Round of Extensive Flight Tests Completed: New Video Posted!
SubSonex primary test pilot Bob Carlton was in-town again in late September during a perfect week of flying weather, allowing Bob and the SubSonex development team to conduct another round of very extensive flight testing with JSX-2. All aspects of performance were explored, as we continue to expand the SubSonex envelope. We're pleased to report that the aircraft performed flawlessly, and continues to exceed our expectations in it's performance and handling. A new video featuring excerpts from these flights has been posted to YouTube!

Now is the Time to Get Your Jet!

If you’ve ever dreamed of owning a personal jet, now is the time! The SubSonex extends the Sonex Aircraft 'Reality Check' philosophy to become the first truly practical and affordable personal jet for recreational flying. The first benchmark on the SubSonex 'reality checklist' is the fact that the aircraft is a reality as an Ultra-Quick Build Kit, complete with engine, that leaves only the most minor items for the customer to source, and the most basic of construction tasks to complete. When you are flying a SubSonex, the $100 hamburger never tasted so good!

Ultra-Quick Build Kit for Experimental Exhibition Category:
The SubSonex Ultra-Quick Build Kit is intended for flight under Experimental Exhibition category rules. Without the "51 percent rule" restrictions associated with Experimental/Amateur-Built airworthiness certification, the SubSonex will ship with a pre-assembled fuselage, wings, tail and control surfaces with canopy and windshield installed. The SubSonex customer will install the easily removable outboard wing panels, engine and fuel system, bolt-in the retractable landing gear, install avionics, electrical systems and controls, install the pre-molded fiberglass components and upholstery (sold separately), and add paint. Under Experimental Exhibition category regulations, SubSonex customers will also have the freedom to take advantage of builder assist centers or aircraft finishing services to do the work for them!

Just like our regular Quick Build Kits for the Sonex, Waiex and Onex, the SubSonex Ultra-Quick Build Kit assemblies are constructed in Oshkosh, WI, by Sonex Aircraft, LLC staff.

Experimental airworthiness certification under the Exhibition category is perfectly-suited to the mission of an aircraft like the SubSonex as it's certainly an aircraft want to show-off at organized events. You can either fly the aircraft cross-country to an event, or utilize the SubSonex's easily removable outboard wing panels to transport the aircraft in a compact trailer. Pilots used to flying warbirds, competition aerobatic planes, sailplanes or other specialized aircraft are well-versed when it comes to working within the operational restrictions for exhibition aircraft, and the kit construction freedoms afforded to aircraft in this category is a perfect fit for the desires of most SubSonex Personal Jet customers.

EAB Quick Build Kit Also Available:
For those desiring an Experimental Amateur Built kit, an EAB Quick Build Kit is also offered. The EAB Kit will include all featured mentioned above, however, customers will need to construct the aircraft tail and control surfaces to meet EAB eligibility. The major difference between amateur-built and exhibition certification lies in who must construct the major portion of the aircraft. The choice of whether or not the customer wishes to hire a professional builder or shop to complete the aircraft will typically be the deciding factor. For customers outside the US, the certification requirements of amateur-built aircraft as opposed to experimental exhibition aircraft may be a deciding factor. All other differences are relatively minor. A downloadable Experimental Exhibition vs. EAB Summary has been prepared to help SubSonex customers make their decision.

SubSonex Kit Delivery:
Like our regular Quick Build Kits, SubSonex Ultra-Quick Build Kits shipping to most areas of the lower 48 United States ship via specialized transport, and do not need crating. International orders will be shiped via 20" FCL Container, and a container packing fee applies. Separate transportation expenses apply for all shipping options. See our Shipping/Packaging Page for more information about Quick Build Kit shipping.

About the Aircraft:
Nobody can deny that every pilot’s fantasy is to own and fly a jet! The SubSonex is designed to capitalize on new generation small turbine engines to give pilots of more average means the title of Jet Jock. SubSonex is all about taking a thrilling rocket ride around the neighborhood!

The SubSonex Personal Jet concept was first unveiled at AirVenture in 2009. After successful pairing with the PBS TJ-100 engine, the SubSonex JSX-1 prototype achieved first flight in August 2011 and completed a successful flight test program in 2012. The JSX-2 model of SubSonex first flew on July 12, 2014 and is flying in aerobatic day and night airshow performances around the country.

Read the SubSonex Test Pilot's Report in AOPA Pilot:

The SubSonex is featured in the December, 2012 issues of AOPA Pilot and Turbine Pilot magazines! The article, "Jet in a Box: Some Assembly Required" is written by SubSonex lead test pilot Bob Carlton and covers the SubSonex flight experience, as well as some of the aircraft's history and our plans for the future of the design.

JSX-2 Features:
JSX-2 incorporates many new features and enhancements, including fully retractable gear with a steerable nose wheel, a full-airplane ballistic parachute system, larger cockpit, increased fuel capacity and more:

  • Larger Cockpit: SubSonex JSX-2 aircraft features a larger cockpit using a straight section of parallel longerons which maintain the 24" cockpit width from the pilot's shoulders to the windshield bow.

    More instrument panel space allows
    modern EFIS systems or tablets!

    Using roughly the same overall dimensions, some changes in seating geometry add to the increase in cockpit width to offer more leg, knee and head room (above).

  • Larger Instrument Panel: The larger SubSonex cockpit allows for the installation of a larger instrument panel to fit a wider range of modern avionics, including iPad/tablet installation.

  • Ballistic Parachute Recovery System:
    JSX-2 allows for the optional installation of a ballistic parachute full-aircraft recovery system. This eliminates the need for a pilot-wearable parachute, greatly improving seating comfort and further increasing available cockpit space.

  • Improved Lines/Aesthetics: Sculpted lines in the nose area of the aircraft combine with dimensional and geometric changes to the cockpit area to give the JSX-2 a far-more aesthetically pleasing appearance from nose to tail. Fully-Retractable Landing Gear also adds greatly to the aesthetics and performance of the design.

    The side view of SubSonex JSX-2 shows off the new variant's appealing lines: from the redesigned nose and cockpit, to the fully-retractable gear, to the sculpted look added by the tail strake.

  • Fully-Retractable Landing Gear: SubSonex JSX-2 aircraft features fully-retractable landing gear with steerable nose wheel. The retractable main gear uses dual-truck wheels for safety and redundancy at higher runway speeds with integrated hydraulic brakes similar in-design to the innovative and highly-successful AeroConversions AeroBrake system, and integrated shocks using heavy-duty springs vs. higher-maintenance oil-filled systems. JSX-2's braking system has been upgraded to provide braking on all 4 tires, for twice the braking power vs. early JSX-2 prototypes.

  • Larger Fuel Capacity: The SubSonex has increased fuel capacity of 44 US gallons (40 gallons usable with supplied Explosion Suppressant Foam (ESF) Cubes) using a rotationally-molded cross-linked polyethylene fuel cell, making for a very robust and rupture-proof tank design (right).

  • Removable Outboard Wing Panels:
    Removal of the aircraft's outer wing panels is a one-person task that is simple and easy. The fuselage with wing center section will easily fit into an enclosed trailer along with the removed outboard wing panels.

  • Autopilot Compatible: Although long cross-country flying isn't part of the SubSonex's intended mission, the aircraft's control system is fully-compatible with today's new generation of lightweight and compact autopilot units.

  • Optional Smoke System: The SubSonex JSX-2 design will feature an optional integrated smoke generator, further increasing the jet's fun-factor.

Same Great Engine: The PBS TJ-100 Turbojet!

The TJ-100 turbojet engine is produced by PBS Velká Bíteš of the Czech Republic, a large manufacturer of rotary machines with roots dating-back to 1814. The TJ-100 is designed for UAV, UCAV, experimental aircraft and motorized gliders with hundreds of units delivered since its introduction in 2008. The engine is a true "plug & play" package featuring integral ECU, starter/generator and oil system, and ships complete in the SubSonex kit with instrumentation, throttle control, pre-wired harnesses and other installation components. The 247 lb thrust engine continues to exceed the expectations of PBS designers and customers alike, with flawless performance and an outstanding service history, all backed by top-notch customer service. The TJ-100 can fit in a small crate to be economically shipped for service, and PBS can turn-around inspection and overhaul service orders in a single week.

Pilot Qualifications: How to Become a SubSonex Pilot!

Because there is no Type Certificate available for the SubSonex, pilots will need a Letter of Authorization (LOA) from the FAA that is specific to the aircraft. Working commercial pilots operating jet or turboprop aircraft can easily qualify for the LOA. Pilots without previous jet experience can also qualify via the Desert Aerospace BonusJet training program. Check-out the SubSonex Transition Training Webinar!
