    Sonex Aircraft is pleased to announce the development of a 2-place variant of the popular SubSonex Personal Jet! SubSonex JSX-2T is designed to be the lowest cost jet trainer ever! It will be a perfect trainer for the single-place JSX-2, and for those who want to share the unique experience of jet-powered flight in a light aircraft.


    JSX-2T is configured with side-by-side seating for optimum flexibility in CG/loading and offers an ideal training environment for its crew. With a wing span of 21.8 feet JSX-2T will have similar wing loading and handling to the single-place JSX-2. The two-place jet will utilize the same proven PBS TJ-100 turbojet engine system. An optional, more powerful PBS TJ-150 will achieve even higher performance.

    Customers and media representatives are invited to attend the Sonex Aircraft Open House and Homecoming Fly-In event on Sunday July 21st at 10am to learn more about the JSX-2T, its projected development timeline, and how customers can get in-line for their own 2-place SubSonex. The event is held at Sonex Factory Headquarters on Wittman Regional Airport the day before EAA AirVenture Oshkosh 2019 begins. A forum will also be held at AirVenture on Wednesday, July 24th on Forum Stage 5 at 11:30am.

    JSX-2T Estimated Specifications & Performance
    Length 18′ 7.75″ [5.68 m]
    Wingspan 21′ 9.6″ [6.65 m]
    Wing Area 87.2 sq ft [8.1 sq m]
    Height 5′ 8.2″ [1.73 m]
    Width with Outboard Wing Panels Removed 7′ 6″ [2.29 m]
    Cabin Width 42″ [106.68 cm]
    Empty Weight (estimated) 530 lbs [240.4 kg]
    Gross Weight 1500 lbs [680.39 kg]
    Useful Load (estimated) 970 lbs [440 kg]
    Fuel Capacity 50 U.S. Gallons [189.3 l]
    Baggage Capacity 40 lbs [18.14 kg]
    Stall Speed (estimated) 65 mph [104.6 km/h]
    Cruise Speed (estimated) 200+ mph [321.9+ km/h]
    Never Exceed Speed 275 mph [442.6 km/h]
    Load Factors (Utility) +4.4 Gs, -2.2 Gs
    Load Factors (Aerobatic) +6 Gs, -3 Gs
    The SubSonex Personal Jet aircraft first began development in 2009, and is now being sold around the world as the most popular and affordable kit jet aircraft. The SubSonex, a popular and serious aerobatic airshow performer that delivers high top speeds and a true fighter jet feel, also shares the docile, low speed handling characteristics enjoyed by the Sonex, Waiex, and Onex designs. SubSonex JSX-2 kit+engine+completion costs start at under $114,000. Sonex Aircraft’s target for the SubSonex JSX-2T is to offer a 2-place jet that can be built and flown for under $140,000!

    JSX-2T is destined to be an outstanding choice for those demanding an affordable 2-place recreational personal jet!

    Wow, they will likely have a winner with that one. Has the prototype flown?

    Looks fun. Maybe more room than typical Sonex since it has more space up front minus the engine.

    Pretty cool. Do they list the range or endurance specs yet?

    Why does it cost almost $30,000 more than the one seat? (with same engine)

    That's a silly question. If you don't like it go buy their competitors two place personal jet. Oh, wait!

    It’s probably the diamond and ruby encrusted passenger seat.

    Wasn't really a silly question .......but the response definitely was.
    Whether a competitor has a comparable aircraft or not wasnt the question nor the issue addressed.
    BBerson asks a straight forward and honest question that I've often wondered myself...
    Why does the 2 place version always have a price tag that is SUBSTANTIALLY HIGHER than the single place version and often times they utilize the same powerplant.
    For the most part,they are the same aircraft.
    There isn't much material difference between a single seat and a two seat aircraft.....certainly not enough to justify the price difference.
    I'm sure the typical response is going to be that they are 2 totally different aircraft and you're paying for the r&d.
    But that still doesnt justify the EXTREME price difference when you add up the materials.

    I can see several possible reasons for the price difference. First is R&D cost and tooling. Second is supply and demand (more demand for a two-seater, and the third is maybe their profit margins on the single-seater were too slim (or maybe a little negative, requiring a make-up effort). One last thought, has the leadership changed (I know they lost someone in that crash awhile back). Also, the metal gauges might be heavier to support the added weight or an expanded g-envelope.

    Heck, for just a little more than the listed kit price I can offer a 2 seat jet with more range, speed, pressurized, air conditioned, and NO ASSEMBLY REQUIRED!

    Yours may have a little more expense in the care & feeding department. ;)

    Wow. A decimal point too far to the right for a toy from my point of view, but I suspect they'll sell quite a few to folks with more disposable income than I have. If only it weren't so ugly...

    On a sort of related note, I was poking around a local airport this past weekend and found a BD-5J in a hangar... not just any BD-5J, but the actual aircraft that was flown by Corky Fornoff in the James Bond movie "Octopussy". Purchased from the museum where it was displayed for 20 years, it's now awaiting restoration. Even cooler for the owner, he has a photo of him standing in front of the plane with Corky at Oshkosh when he was 11 years old. He's planning to replace the original engine with the same engine the SubSonex uses.

    The price difference is all insurance cost for the extra seat. One more lawsuit plaintiff, much more money to pay out after the verdict.

    Why would a company price a product based on the cost of their materials? They price the product based on what they expect demand will allow. Then, they back out from that and see what it will cost to actually produce that product. If the company's cost exceeds what the market will pay, then you don't build that product. Play with the expected costs and retail price a lot of times to determine what combination(s) maximize profit (which is the point of this entire exercise).
    When other competitors enter the market, they will have done similar calcs and will presumably have concluded they can offer a similar product that offers better value. Now, you have to go back and see if you need to change anything to stay competitive.

    Not really if you understand business. R&D should be less since they've learned a lot from the single seat.
    A business took a chance with a single seat jet and offered it to the market with a smaller profit margin to help sales. Sales end up as expected or better so you offer your new two seater with a higher profit margin. If sales are a little slower than expected you knock $10,000 off. You still have a decent margin and customers say "Wow, 10,000 off, what a deal.

    Meh... It's Soviet era tractor technology. Just feed it with Jet-A and forget the rest.

    I was wondering how much the Sonex likes to drink, but they seem to have neglected to specify its range?
    That engine would have been better buried in the fuselage to disguise it's diminutive size, IMHO.

    Edit: Engine rated at 0.7l/min at idle, 3.12 l/min at full thrust. Which is 11gph and 49gph

    The single seat SubSonex JSX-2 (same engine) has a fuel capacity of 40 gallons and a range of 480 statute miles (with 30 minute reserve). Cruise speed is approx 240 MPH. I don't know if the range was at cruise speed, but if it was, then it burns about 20 GPH. The new 2-seater carries 10 more gallons of fuel, it looks like they estimate it will cruise somewhat slower.

    Of course, you can't justify any of this if you are looking at GPH, range, payload, speed, purchase price, etc. The customer has to want a jet for its own sake.

    TJ100 burns 1.1376 lb/lbf/hr (292lb thrust)
    TJ150 burns 1.1670 lb/lbf/hr (337lb thrust)

    If you want a cheaper airframe, put one (or two if you have excess cash) of these engines on the back of a cheap Long-Ez or Vari-Ez.

    Heh, I didn't realize the subsonex cruised at 209kts, now I feel the need to look more ;)

    I like it! More turbines!
