i got the 850, video only works in 1/2hr spurts, so i guess you'd have to land and reset every 1/2hr... but i lost the instruction manual before i could savy up on it, so maybe its just something i'm doing wrong... zoom is crappy for any decent video from a distance, but <50m seems ok enough... too lazy to be bothered mounting camera to kite or head, or maybe just not showy enough...
