For example, the US <https://en.wikipedia.org/wiki/Federal_Aviation_Regulations>Federal Aviation Regulations prescribe the following limits (for the most restrictive case): * For <https://en.wikipedia.org/wiki/Transport_category>transport category airplanes, from -1 to +2.5 (or up to +3.8 depending on design takeoff weight)<https://en.wikipedia.org/wiki/Load_factor_%28aeronautics%29#cite_note-9>[9] * For normal category and commuter category airplanes, from -1.52 to +3.8<https://en.wikipedia.org/wiki/Load_factor_%28aeronautics%29#cite_note-Far23-10>[10] * For utility category airplanes, from -1.76 to +4.4<https://en.wikipedia.org/wiki/Load_factor_%28aeronautics%29#cite_note-Far23-10>[10] * For acrobatic category airplanes, from -3.0 to +6.0<https://en.wikipedia.org/wiki/Load_factor_%28aeronautics%29#cite_note-Far23-10>[10] The KR plans state that the design load factor is +or- 7G's at 800 pounds. 7x800=5600 pounds. If you fly the KR at 1200 pound gross you have a "design" structure of +or-4.6 G's. I say "designed" as in assuming it is built properly. I licensed mine at 1350 pounds gross. While the structure is quite strong remember that even slight increases in weight have a substantial effect on performance. More weight necessitates more horsepower which comes with more weight which necessitates more horsepower which comes with more weight, and on and on and on......... Larry Flesner
