Interest in building the Carbon Dragon continues.  While the design concept is decades old,
the world has yet to produce another sailplane capable of exploiting extremely weak lift or Microlift.

This photo was shot by S. Steve Adkins through the moon roof of Gary Osoba's tow vehicle.
Steve auto-towed Gary to a height of about 300 feet.
Location: Harris Hill just outside Elmira, New York

To perform the tow, we used 750 feet of line (we started with 1000 feet).
The weak link was two strands of heavy cord (almost string).
No wing runner required, an arm out the side can level the wings!
The tow vehicle is driven down the 1000 foot paved runway ...
and off into the grass and down the hill turning and stopping just before the drop off.

Years earlier, a man died performing a similar auto tow.
He drove off the cliff of Harris Hill.
I didn't find this out until years later.

This site is for builders and pilots to share info about the Carbon Dragon.

Do NOT contact me for plans ... I can not give any additional tips or help in obtaining plans.

I do not have Carbon Dragon plans
I am no longer building a Carbon Dragon
  I lack the skills to redesign and build a Carbon Dragon to fly at my weight.
I am insanely jealous of people who fly microlift gliders ... see my entry:

Breaking News ...
09-27-2005: Jonathoan Pitt just sent me a few photos demonstrating his excellent quality of worksmanship.  Jonathan reports that Yasushi Akahori in Japan has finished his wings and is now starting on the pod and is up against Jim’s famous pod building instructions, “Building the pilot pod seems to be pretty self-explanatory.”

Hi Steve,

Just thought I'd let you know that I've now completed the first UK homebuilt Carbon Dragon.  Waiting on the Uk weather for the first test flight.  Final finished weight 159 pounds.

Recently  I have had tremendous  support and generosity from Ozzie Haynes who I believe is the 1st British / UK builder.

Purpose: This website was created to gather and share information about building and flying  the Carbon Dragon sailplane.  This includes derivations from the original prototype.  Jim Maupin always stated that his goal was for the design to lead to refinements and improvements.  

Introduction: The Carbon Dragon is an ultralight, high performance glider.  This glider was conceived by Jim Maupin who also designed the famous Woodstock sailplane and the Windrose motorglider.  Jim received encouragement from Irv Culver, who promised to "run the numbers".   As a result, Jim Maupin with an assist from co-designer Irv Culver, produced an exciting sailplane for  473 plan sets have been sold.   The detailed plans were drawn by Bill Baker whom Maupin described as, "...  a fellow home builder and consummate draftsman."  Many people, who have flown the prototype, have commented on its excellent handling.
