Yikes!!! The white balance on the Typhoon is off. Green appears brown due to the camera enhancing the reds. Unfortunately this is all too common in most Typhoon H vids, but it can be easily fixed with manual settings.Me and my bud were out for a flight yesterday and he wanted to follow me for some video.
I made it out 1.1 K with a solid video link. He was using his P3 Advanced and lost video at about 800m.
