Kitplanes, January 2000, reports that 35 Carbon Dragon sailplanes are built.  Below are listed 9 flying and 18 building.  Don Santee in "The History of the Sailplane Homebuilders Association" reports 110 sets of drawings sold, 3 built and 2 flying.  I am the holder of drawings set #248.

New Website: 
Stéphane has created a new website with the largest number of contruction and flying images of the Carbon Dragon. 
- A must visit website -
A photo at this website shows the bare frame which looks too pretty to cover.  Just before covering,  Stéphane reported1300 hours work.  Stéphane is in the covering process and hopes to fly before the end of the year.  More photos!  Very detailed

Now flying!  See 5 great photos at:
Daniel reports, "After four years of building, and of course at least one sleepless night, the first flight of my great love affair has been performed last sunday, december the 17. 2000, at the airport of interlaken, by towing behind a car.  First "flight" was just about 5 meters above ground to make sure the plane does what I expected of it. Then followed two towings up to 200 meters ground.  Thanks a lot to any body for all the help, whether it was support in building, technical advice, encouraging, or just doubts if this thing would ever fly!  Well it does - an as far as I could find out in the short flights - it does quite well!!"  Previous reports:  Building stronger wing.  Complete load test at 4G (with total weight plane + pilot 150 kg) two-piece door in place of one-piece. I have redesigned the wing and horizontal-stabilizer with CAD to produce with CNC. DXF-files are available.  Move wheel back.  Concerned about plans vs. amount of aileron deflection.

Steve Arndt   
update 1/14/2002 - Steve has racked up many hours flying two seasons at Wallaby Ranch in Florida for two seasons.  More recently, Steve replied to my question about twin engines for the Carbon Dragon, "Yes, twin model airplane engines.  I have them both in the shop.  They weigh just 4.7 pounds each and each will generate 8-10 horsepower depending on prop efficiency.  I think one would do but two should give an excellent climb rate.  I'm redesigning the fuselage to accommodate them and a retractable landing gear." 

Debuted at SHA Workshop in Elmira, New York in summer 1999.  Extremely beautifully finished sailplane.  The CD was not allowed to fly at the workshop due to county restrictions. For photos, visit: 
These photos tell it all.  Much of the 1/32 nd plywood was replaced with a combination of two layers of carbon and one light outer layer of fiberglass.  Steve included a BRS.  Steve has completed a static load test for his flying weight. Wing was built using pre-formed composite wing skins which were formed over the wing.  Built carbon fiber gap covers for the tail pieces.  Many innovative changes without compromising the design.  Jigs shown at the last two workshops demonstrated great creativity. 

....UPDATE ....
1/25/2000 - Steve Reports:  "Got back a week ago from a trip to Wallaby Ranch hang glider flight park near Orlando,  Florida.  Trailered the Dragon down.  I flew for four days and logged a total of just over 19 hours of airtime!  The glider is a blast.  First to soar, last to land.  I'm going again every month this winter." 
....UPDATE ....
October 16, 2000  Since then, Steve has flown over 90 hours in his Carbon Dragon.  For a synopsis of his building process and thoughts on this design, visit: 
About three years ago Summer 1999 Concord 
New Hampshire
Jim Maupin  Now owned by Gary Osoba , prolific writer, who has made notable flights in  the Prototype built by the late Jim Maupin.  Jim built this glider extremely light as a proof-of-concept.  Goal was 100 pounds, actual was 145 pounds.  Normally, no homebuilt is ever built as light as the designer's prototype.  Note: a crescent wrench is "permanently" duct-taped to the tail to improve the CG.
Please do not contact the Maupin ... they no longer sell plans

Graham Betts  Changed incidence on H. Stab.  Building parallel to the boom results in heavy nose down pitch.  Also, Betts at 198 pounds, changed his seating position towards the rear which required extensions on the rudder pedals. SHA 12/97 -  2/1/96 
Flight tested the Carbon Dragon at high speed for flutter, oscillations or instability.  Noted that cutting carbon fibers damages saw blades.  Controls are light, easy to thermal, plenty of stall warning, spoiler is effective, and large rudder is effective ... from Kitplanes, page 32 - - PO Box 10492, Wellington,

Alan Sayers  
504? 5/2004:  I intend to start building within the next six to eight weeks. I am currently "building" a 3D model in CAD / modelling software as I figure it will save me some time in the long run. I have digitised the airfoils for every station  and am checking the camber, thickness and reynolds numbers to get a better understanding of Irv Culvers approach. I also intend to run the airfoils through XFoil and to run the 3D wing / model through some fluid flow cfd software I have available. 

Have received some great help so far ..... Ozzie Haynes, Doug Hoffman, Yasuhi in Japan, David Swanson kindly sending me details 
of Irv Culvers twist analysis, Dan Howells drop dead 
gorgeous LightHawk wing. Stephane Abbett also responded by email.

#401 Hi, I just bought a set of Carbon Dragon Plans #401 from Guy Farser .  I already own a Woodstock glider.   Do you Know of anyone that could help me get a copy of the builders manual for the Carbon Dragon . My plans arrived in the origanial tube that Guy recived them in but the tube was open on one end when they were delivered to me . Regardlees there was no builders manual inclosed . So now I have the plans and no builders manual . 
I don't know what to do about that yet . just try to find one . 
I will start building and cutting parts while I search for a copy of the builders manual . 
If you would like to add me as a builder please do .

#504 Unfortunately I was a little too late to obtain plans from the Maupins, just missed out when I went to place my 
order.  I intend to start building within the next six to eight weeks. I am 
currently "building" a 3D model in CAD / modelling software as I figure it 
will save me some time in the long run. I have digitised the airfoils for 
every station  and am checking the camber, thickness and reynolds numbers to

- Many project photos at including carbon parts, tail feathers, carbon spar, spar box drawings.  A must see website!  First contact with Ya was 5/14/2002 
Newest images (Feb 2005) demonstrate load testing.   Other builders have commented on the help they received from Ya and his website.

- I have started building and would love to coordinate in any way.  Anything that will reduce the time time taken is welcome, so get in touch with me.  I'll put up a website on my CD progress as soon as I hit 10% or so.  I am building a single plane together with Matt Ruddell.  Hopefully it won't take 
too long.

A very improved, modern Carbon Dragon-like glider being produced in Chili.  Its name is MANQUE which means Condor in mapuchean.  Note: for nearly 50 years, gliders have been built in Chile. 

See website, Aerodynamic Analysis of the Carbon Dragon Airfoils.  Also, producing carbon seat pan for sale.

Erik J. Brans  
- Progress is slow for a variety of reasons including a new baby and moving. At the moment I am carving out a working space for my CD and will continue with the production of the wing and flaperon ribs. The empennage is finished.  Because I am heavier than Maupin, I have chosen a slightly stronger carbon on advice of AMOCO, where I bought the carbon (Thornel T350/35, 12K, 309NT) and will build the wing in a way that the leading edge is in one line, that moves the pressure point forward just enough to compensate for my heavier weight. 
- The Netherlands 
Kevin Lane 
- Kevin is currently 75% done with the empennage and will start the wings this winter. 
... update 7/24/2001 ...
We just moved back to our first house, so I have to set up the shop again.  I have one half-completed flaperon and the empennage hanging up in the rafters.

Mark Crist  
Mark is in Iraq for a tour of duty.  All building plans are on hold.  Recently, Mark decided to build a  Sandlin BUG.  His CD Plans have been sold.  Mark sold Carbon Dragon parts and plans.  See: 
Tail pieces, wing ribs, carbon hinges are finished.  Using H. F. Blanton's plywood kit. The wing mid-ribs were built on Mark's kitchen table. Presently building a "Bug" ultralight. 
Steve Adkins  
(me, the webmaster)
Built mockup of the front half of the pod.  Cockpit space is on par with the K-21 if you add 1 inch in width at station 24.0 to reach 18 inches (I believe the original design was 16 inches and expanded to 17 inches before completing the prototype). Project on hold due to pilot weight. 3/1998 Twin Cities
