I took it out yesterday for a test flight at Tulloch Lake and did a couple passes and tests in GPS mode and then got a little gutsy and decided to test what I could do in smoothness of control in Atti mode. Now I have flown non-gps enabled quads for over a year prior to my I1 but I have gotten spoiled by the I1. Flight conditions was cloudy but glarey (wish I had my ND filters with me) and very windy (small gusts but mostly steady up to 25-30mph) Let me clarify for the safety nazi's I was in a state park controlled boat launch, campground and marina and before I took flight I checked with park officals, security, and the ranger and all gave me the green light as long as I stayed 150ft above the dam (which was about 1.5 miles out from my position), stayed away from the power lines that were just to the east of my position and the lake residential community just to the south of my position. Other than that it was "Have fun, be safe and thank you for asking first". At about 1:50 in the video I took off after a beautiful V-Cat power marine boat. I started in GPS mode but he accelerated much faster than GPS was going to let me go so I switched back to Atti and you can see some of the issues I had keeping pace with him, especially once he started turning. lol. All in all the majority of this video was shot in Atti mode and the dam and boat chase scenes were about 3/4 - 1 mile out from my position. But all in all zero complaints.
