The G-1 seems to inspire many ideas and variations, as shown in the photos below.
These are some of the photos sent to Vortech of customer-built G-1's.
Bear in mind that Vortech will pay for some good flight or test video of
your own project (subject to terms).

A little G-1 background:  The unique G-1 Ultrtalight Helicopter, created in the early 1970s by Art Weilage, 
was tested and sold as low-cost kits by Compcop, Inc.  Vortech offers the original construction prints to
hobbyists curious about this design, or who want to study the concept as inspiration for a design of their own.
