(all this is in fact true)
From 1979 to 2010 I sold over 100 of these machines including kits and plans. They're easy enough to make that it's probably the most ripped off design on the web. I've found 3 bootleg copies and heard of several more in other countries. But now they're officially free. Some watermarks for Dragonflypower.com might still be on some of the gifs. (That was my domain name which I abandoned, it was bought up cheap by someone who expects to get rich selling it on as soon as all the other names have been used up, or maybe they researched histories of the hits it got in the '90s and think the good'ol times are just waiting for the next hippy revolution when it'll shurely be worth millions.) Here's the Wayback Machine link without graphics. Tell me if you find any of those gifs and I'll remove the name, or maybe not, I'm shure the present owner is desperate for references.
