So i have clocked up nearly 3 hours flight time with my spark and to be honest it is just getting worse the photos have become the size of thumb nails with extreme poor quality the video is getting more and more jumpy with lots of pixilation connection between rc and drone is dropping out and coming back within 10 meters max flight distance i have got is 160 meters but then had full disconnect and rth kicked in i did a compass re calibration and tried to do an imu re calibration but it got stuck on step 2 for 60% of one battery i understand the spark is new but really a useless tool to me the way it is
