Old news
I have been following the Icon since about the beginning of the summer. Designed by some of the guys from Scaled Composites, looks great, and is feature packed. But as with many things, I think it's too good to be true.
You mentioned the lack of footage of the plane taking off from land. I was surprised that Icon did their first flight off the water, normally most budding seaplanes test of land first...I thought it was pretty cool.
At Oshkosh they had a full size mock-up on display, which was in the front folding and unfolding it's wings, and on the side on a trailer they had the one that actually flew. Why was it on a trailer? The one that flew has no landing gear! Yup, it's just a ASES right now...
Additionally a friend pointed out to me a serious design flaw...the spiffy canopy.
The canopy is a glass bubble that hinges forward...this works fine for most normal planes, but the Icon is not normal - it's a seaplane. What's going to happen when someone leaves the gear down while landing on the water (and it will happen, there's potentially going to be brand new sport pilots owning and flying these). In the case of a gear down water landing, the plane would most likely flip, submerging the canopy. The water pressure will probably be too great for the pilot to open the canopy and escape. Many similar planes (Sea Ray) uses a sliding canopy because of this problem.
Finally, the price...it's pretty expensive, and as we all know, the price will only go up due to inflation, increased production costs, etc.
I wish them the best, because the Icon has potential to be an incredible plane, but I just don't see it making it.
