For Christmas I received a Syma X11 Hornet quadcopter to learn how to fly. The videos make it look easier to fly than it is. Looking around YouTube for flying tutorials I came across a video of a Phantom quadcopter survey of a large flooded quarry. It has some nice images of submerged vehicles and tools in the water. Hopefully the embedded video in this posting can be seen at the end of this posting. If not, here is the link to it on YouTube: https://www.youtube.com/watch?v=nvj4Tnsv0t0
If I can be able to fly this small drone with some skill I can move up to one with a camera so that one day I can use it to survey for fossils.
