I plan to shoot video of whitewater kayaking. I made some cheap and easy floats for the Phantom just in case it falls in the river. If that happens, I know it will likely get wet inside and do some damage but at least I might be able to recover it. The quad floats pretty level and stable with the bottles. In calm water, the battery and other electronics did not get wet. I temporarily moved the compass for testing and taped it to the top of the quad to keep it dry. I made the floats from small 8 oz water bottles which are very light weight. I drilled holes in the caps to match two holes in each of arms where the motors mount. I used the longer screws which came with my prop guards and placed washers under each screw head to make sure the screws did not go too deep. The Phantom seems to fly OK with the bottles attached, although wind does affect it more. It is easy to unscrew the bottles when not flying over water and the caps can be left in place.
