The ICON A5 has some serious design flaws. Notably, if it goes onto its back, as seaplanes sometimes do, you're in deep do do. Good luck getting that canopy open. Secondly, on the downwind to upwind taxi turn discussed in the Searey video note that the ICON has no wing sponsons. A good crosswind will lift the upwind wing putting the downwind wingtip into the water. At best this will prohibit you from getting turned into the wind. At worst it can roll the aircraft over in the water (then see first objection). As for its "spin-proof" wing watch their comparison video carefully where they stall it beside a C-150. When the pilots push hard right rudder and full up elevator look at the respective motion of those surfaces. The ICON accomplishes its "protection" with severely restricted control throws. Good luck trying to do a strong crosswind landing. Personally, I want the ability to fully stall and spin my aircraft. Limiting the max attainable alpha is a poor substitute for proper training.
