Yes, those are my numbers. I've always noticed my bird would go up at 11mph upon full throttle in ad straight up vertical ascent before this week. Yesterday in 55F sunny conditions, just after my 1.6 upgrade, full throttle straight vertical ascent fluctuated between 5 and 6 mph. I also noticed that when giving it full throttle up and full forward simultaneously, the ascent angle went from about 35 degrees to about 15 degrees. This is something I do all the time, I can see the difference, so I know DJI has put a current draw limitation on the system that reduces the snappy performance it use to have, and it's not just in cold conditions, although it might be even worse performance in 30F weather.
