I see the Carbon Cub EX approved to 1800+ pounds but can be amateur built and certified at 1320# so it can be legally flown by an LSA qualifying pilot. The Cubcrafters site does not specify the kit is eligible as E-LSA but only amateur built. Interesting. The questions are
1) when during the build process is the gross weight declared?
2) with the future potential increase of gross weight for no-medical pilots, could a 1320# amateur built Carbon Cub be re-declared to have a higher gross? I understand that a higher gross airplane can't be reclassified for LSA but I've never seen anything about increasing the gross.
