Don;
The 3-cylinder 2Si 2-stroke was the featured engine for the "Lightning Bug" composite 1-place homebuilt. A zippy little plane, you can Google it, but the problem is that the 2-strokes are quite a bit lighter than any of the 4-strokes that are typically employed on KRs so it would require a longer engine mount and cowling for W&B. Probably not as exaggerated as Mike Ladigo's turbine engine powered KR, but longer than a VW or Corvair mount. Oscar Zuniga Medford, OR
