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.

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.

racked up many

about twin engines for the Carbon Dragon, "Yes, twin model airplane
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.

||504?||5/2004: I intend to start building within the next six
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,
and reynolds numbers to get a better understanding of Irv Culvers
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
||#401||Hi, I just bought a set of Carbon Dragon Plans #401 from Guy
. I already own a Woodstock glider. Do you
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 .

The empennage is finished. Because I am heavier than Maupin, I
chosen a slightly stronger carbon on advice of AMOCO, where I bought
carbon (Thornel T350/35, 12K, 309NT) and will build the wing in a way

|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).
