The problem with that is, as the center section is reduced, the outer sections have to be made larger to provide the same wing area. For example, on the KR2S: wing center section 30 sf outer wings 52 sf 63% of plane's weight supported on waf's change center section to 36" span (round numbers to match fuselage) wing center section 12 sf outer wings 70 sf 85% of plane's weight now supported on waf's This doesn't mean that it _can't_ be done, just that there are now larger forces on the WAF's and the wood they attach to, and you must re-do all the engineering and calculations to make sure things will still work. A possible exception would be to put the KR2-S outer wings on the reduced center section of a KR-1. This would give you very close to the original wing area of the KR-1, and less stress on the WAF's due to the lower gross weight. -- Regards, RonB
