I just finished the build today and went out and did the maiden flight. I printed the plans at 110%. CG was perfect as per the plans. It flew for about 20 mins on a 3000 Mah battery. I could likely go 30 mins but I was having so much fun flying full speed most of the time. I took it up high and let it glide and it floats great. I am posting just the tail end of the 20 min long flight video as well as some details of the build.
