Lads holiday MTBing in Wales and Hereford. The drone was following great until the end of the video until the riders go behind the tree and it lost them, bit of a poor show there as it wasn't exactly for long, I thought it was supposed to be able to handle that sort of thing. Needs more testing, only had it a few days. F11 focused to infinity, not the sharpest video but good enough for the active track test.
It was the last rider, I initially chose the middle rider when they where closer together but for some reason it selected the last one which turned out to be a better choice I think.
