To add a little fuel to the fire here's a link to John Monnett's Xenos Motorglider web page with the FAA and JAR definition and criteria of a "Motorglider" - be aware that to legally operate a motorglider with a private pilot's license you need a glider rating with a motorglider endorsement. So unless you have those two additional pieces in your pocket you can't build a KR1-B and thumb your nose at the FAA while flying with out a medical (how every satisfying that might be).
