There has been a lot of discussion about flight times. So I decided to do a test, I believe the Naza battery warnings are very conservative. I have been flying electrics for 6 or 7 years, mainly Heli's and have always gone by the 80% rule. So here are my findings on a Stock Phantom 2200 battery. These are new batteries and just broken in. I also have the BeHolder Lite Gimbal running off the main power as well. 8:45 flight time and I put just over the 80% back in, so I need to cut it a bit shorter. Here is the video of the flight so you can see the time and that I am not just hovering around. I have 2 storm 2700's and will try and do another video on them, but I see almost 10 minutes with no problems and just under 80% on the charge. http://youtu.be/g_ACAQHG77c Your results may vary.
