Thanks for all the replies so far. I have been having a look at the HobbyKing kit, and the RC Groups forum, but I don’t think this FPV is actually quite what I am looking for. FPV seems to involve a transmitter sending back a video signal to a Headset / Goggles which the user wears, and pilots the vehicle/boat/plane as though they are looking through the cockpit. What I am looking for is for a video signal to be sent and picked up on my Smartphone, which I can choose to look at, or not, whilst driving the boat. If the Smartphone can record the footage for uploading to YouTube later, then even better. The Phantom Drones do exactly this, which is what I would like to somehow replicate in a boat.
