Claudio has the Genesis Extreme plans now.
Just for clarification, the Genesis is/was more of an aesthetic than an actual airplane design. There have been at least nine different sets of "numbers" onto which the Genesis aesthetic has been stretched. I think of an airplane as a "mannequin" of numbers. Just like a mannequin in a store window onto which different clothing can be draped to achieve a certain appearance, a model can also be looked at as a sort of mannequin. You can drape that mannequin of numbers with a WWII fighter look, a jet look, a racer look, etc.
Genesis 1 through 7 had straight trailing edge wings (no forward taper). The 1980 Genesis had 1 7/16-inch per panel sweep forward. Years later I took that particular mannequin of numbers and added a fin to create the first Crossfire. Even the modern Crossfire designs have had the swept forward hinge line, although the nose and tail lengths have been played with a bit. I have a brand new Genesis that has the same wing as the 1980 ship, but with an inline motor and wing. I like the way the swept forward hinge line wing works in the wind, so I've pretty much settled on using that feature from now on in my designs. I have reduced the amount of forward sweep from 1 7/16-inch to 3/4 to 1-inch of late.
The Genesis Extreme was an experiment to try much smaller than normal flaps, and it featured a straight hinge line. It was built in 2001, and is still flying great and is one of my all time favorites. I just might try that basic wing design with a bit of forward sweep just to see if it gets even better...
Now that I'm retired, I have a lot of time to design, build, and write. I'm working a bit everyday on my Genesis Saga book, which chronicles all the Genesis variants, and the adventures had flying them all over the world when I was younger. I'l certainly announce here when that book is finished and available. It is currently close to 100,000 words in length!
