I am considering selling my Searey and building a 7SS because I have a grand daughter that is interested in learning to fly. Because of medical issues she be looking at light sport. I would want to be able to switch back and forth between amphibious floats and wheels so I could get back on the water every now and then. This leads to the big question that I can't seem to get an answer to. I would want to limit it to 1320 on wheels for her the fly it light sport but go to 1550 on floats to have a better useful load. From what I can determine, once certified outside the light sport weight limits it can't be flown light sport but it looks like this may be a useable loophole that would enable her to fly it light sport. Otherwise at 1430 I'm in the same position as I am with the Searey. More often than not I'm over the legal gross weight limit.
