Proposed gross weight increase for RAA registered Kitfox & Skyfox aircraft

[Fox 4]

some time ago states that kitfox airframes are quite ok to carry an extra 300 lbs if you choose to do so,

 

as the Skyfox could be considered a stronger version of the kitfox ,one could assume that an official weight increase to at least 550 kg should be sought from RAA.

 

One could make the point that at the time the skyfoxes were being produced ,they were only certified to 425kg because that was the maximum approved weight at that time ,test data showed that they easily passed all safety testing with plenty of margin
