The video feed did freeze on me once or twice on the way out but only for a second or two. On the way back I had to drop altitude because of strong winds and the video cut out a few times but only for a few seconds again. It could have just been me tilting the controller from the optimal antenna direction to see the video better from the sun glare on my phone.I think I might have been able to get that with a full battery. You never got a signal drop?
