In 1998 there was actually a tri-gear, twin 2180 VW, 2-place KR designed and constructed by a group formerly known as the Area 51 Engineers. It was called the KR-2T "Tango", as in "it takes two to Tango". A schematic is shown at http://www.flysquirrel.net/KR/Tango01.JPG . Performance wasn't too bad... it cruised at something just shy of 180 MPH.
And if you believe that, then Santa Claus is no stretch of the imagination either! Oscar Zuniga San Antonio, TX mailto: taildr...@hotmail.com website at http://www.flysquirrel.net
