Hi John. Thanks for the compliments. Regarding the cows. The Phantoms are very good at keeping a steady altitude all by themselves. The problems come about because the ground rises and the drone doesn't! I flew very slowly as I did not want to disturb the cows, hence the cuts in the film. Need not have worried though as the drone had the opposite effect. Myself and the drone became surrounded by cows curious as to what we were and what we were doing. It frightened the dog, on a lead, who ended up barking at the when one went nose to nose with her.
Shame you dont live a little closer Id love to give you a free fly to boost your confidence in these machines. Being hi tech they can go wrong, like any device. Usually its because of the person flying either making a mistake or not understanding what they have to do. Buy a cheap, but good one, off ebay. Not the
P4P yet. Practice with that first or even better find someone local who is willing to let you have a fly. I had a nice guy (just in case he reads this

) come over from Wales for a couple of lessons. After half and hour he was shooting the drone off in all directions.
Things to contemplate............. If you let go of the controls the phantom stops straight away and hovers. So if something is worrying you e.g you have flown to within inches of a wall/tree, you can simply let go of the controls while you work out what to do next. If you loose sight of it you simply push the RTH button and it will fly directly upwards, along, and (in theory) come back and land at your feet. NEVER be afraid to look like an idiot and ask questions. No matter how daft you may think they sound we have all been there.............. done that.
As for "you should never fly out of sight" yes your right. We should never go over the speed limit or eat/drink whilst driving our cars either.
