Aw! There it is. The RV-12 can be changed over from S-LSA to E-LSA. There is the clicker.
For the RV-12, it's not a "change over". The builder builds it from a kit, so it's an E-LSA. A change over is when the owner bought an S-LSA (built by the manufacturer) then changes it to E-LSA so he can make mods to it.
