I had the elevator servo quit on a .60 size See Bird about 20 years ago and it hit the water straight in and exploded in a million pieces. It was in 40' of water and I lowered the anchor from our fishing boat to the bottom and tied the other end to a piece of foam from the wing to mark the spot. Went back to the cottage got my scuba gear and went out and followed the rope down with a light and it looked like a plane crash on the bottom of the lake. Picked up the Enya .60, the battery and the servo's, the reciever was still in a piece of the fuse. Lucked out because I marked the spot, it would have been impossable in all that water to pinpoint otherwise. I will never forget the look on my Dad's face cause it was his plane, I was flying it for him, as he was still in the learning stage. He said, " You crashed my airplane!" I don't think he forgave me for that because I always laughed when he would bring it up.
