Re: Best Drone for GoPro???
That video looks like it was taken with a Phantom Vision 2. The PV2 puts out it's own wifi, you log on with your android or iphone, this gives you real time camera view, and flight info (altitude, distance, compass direction etc.) and control over the camera functions. The copter also uses GPS and shows how many satellites you are connected to. When you are connected to 6 or more when launching, it has an automatic return function and will land where it took off from if you lose signal, lose sight of the copter or get a low battery warning. It also has other flying modes which will be necessary if flying while sailing, the atti mode disengages the GPS/return function, if underway you don't want the copter returning to it's original launch site, in straight GPS mode it will auto land with or without you. The PV2 has 6 function settings, I've been flying for 2 months (over land mostly) trying to learn these functions because you will crash while learning to fly, and I've seen the youtube video proof that the camera will continue to record as the copter descends into the deep.
If you wait to do everything until you're sure it's right, you'll probably never do much of anything.
