First test of my Waterproof Quadcopter build in the lake. This is a DJI E300 kit in a Dex shell with NAZA Lite flight controller and GPS. Tests were with a Dinogy 2800 Mah battery and GoPro 3+ in it's housing. Brought it back in after half a dozen landings and takeoffs. All was dry inside. ESC's were barely warm. Battery was at 11.4v on landing after 7 minute flight.
