Any aircraft that meets the criteria of the Light Sport Aircraft regulations (weight, speeds, number of seats, etc.) can be operated under those regulations - there is no need to for an E-LSA certification! This applies to normal certified aircraft and those certified as Experimental Amateur Built.
Here is a link that includes all the aircraft to date the FAA agrees meets LSA criteria: http://www.sportpilot.org/learn/lsa/likely_lsa.html Note the KR2 or S is NOT LISTED. Recommendation is to call it something else and modify accordingly, if you desire to certify it LSA. IF you certify Experimental Amateur Built as most do, and it operates in the LSA criteria: Aircraft with a standard airworthiness certificate that meet above specifications may be flown by sport pilots. However, the aircraft must remain in standard category and cannot be changed to light-sport aircraft category. Holders of a sport pilot certificate may fly an aircraft with a standard airworthiness certificate if it meets the definition of a light-sport aircraft. So Sport Pilots can operate a KR2 or S that operates within LSA Rule criteria. BUT ITS CERTIFICATION WILL NOT CHANGE. It is just allowed to be operated by a Sport Pilot since it operates in the criteria. Anyone wanting to do this NEEDS to DOCUMENT WELL ALL TESTING that confirms compliance so no questions will arise later. Then YOUR version complies. Here are the brief pilot rules: The sport pilot rule: Creates a new student sport pilot certificate Creates a new sport pilot flight instructor certificate. Requires FAA knowledge (written) and practical (flight) test. Credits ultralight training and experience toward a sport pilot certificate providing the ultralight pilot transitions to a sport pilot certificate by 31 January 2007. Credits sport pilot flight time toward more advanced pilot ratings. Requires either a 3rd class FAA medical certificate or a current and valid U.S. driver's license as evidence of medical eligibility (provided the individual's most recent application for an FAA medical certificate was not denied, revoked, suspended or withdrawn). Does not allow carrying passengers for compensation or hire Does not allow flights in furtherance of business Allows sharing ("pro-rata") operating expenses with another pilot. Allows daytime flight only. Allow sport pilots to fly vintage and production aircraft (standard airworthiness certificate) that meet the definition of a light-sport aircraft. Based on what is published today, with attention to details given and testing that supports (make it real cause the FAA just might have a ASI fly your plane just to see - don't put it past them) compliance, there is no reason why the plane cannot be certified as all KR2 and KR2S models previously have been, and then operate under LSA rules.
