L....December
C....1993
U.....Long Wing, NOT Speedster
141.... the number of the kit shipped that month
The 1993 paperwork clearly stated 1050 pounds, but that was in error. You are no doubt 1,200 pound max gross.
Please see Service Letter #30A on the Kitfox Aircraft website for this and more information.
I downloaded all the letters and bulletins and printed them out, and then verified their impact or lack of impact on my build.
