Needed that distance perspective for a radio controlled model sail boat I want to buy thats good up to 50 meters (164 feet for us Yank's) Farther than that you probably lose the boat out of radio range, and then at the winds whims to blow it wherever it wills.
I'm using better than that right now. The yellow remote control, check it out among my current videos. It has a range of 300-350 meters. Although I specifically don't have a range testing video of it.
