I agree Shane, RC subs have this special attraction to disappear somewhere underwater and pop-up in another whole new place, with a really cool looking sub, you can really attract some viewers around you! The Ocean Explorer has two diagonally fixed props on the side for populsion, turning, and diving. My opinion, it's just a re-introduction from the Nikko Seatiger sub (red/black sub with sharkfaced front ). The price seems a bit too much though, compared to the Hobbico "Baby Kilo" 59,99 to 49,99. Ten dollars to spare!
