Urchins' Family 6 Channel Mini RC Submarine Toy (Black)

Fun for 5 minutes but to really work it needs a couple fishing weights to become more neutrally buoyant. Simply taping lead to the sub makes it much more usable in a pool. Otherwise it requires near continuous down thrust to submerge.

Right out of the box, this sub does not sink. It will float. This thing is awesome if you add a little weight! I glued a washer and two finish nails on the bottom. This creates buoyancy, which makes operating this thing a lot more fun. Another benefit is a longer battery life due to not having to force the sub to sink.

This toy works pretty well but, the range is abysmal. Once it gets about 3-4 feet from the controller, it looses signal and does nothing until it regains signal. It uses an internal horizontal propeller in the center to dive, and once you let go of the button it rises back to the surface. It is easy to use, but frustrating on how short the range is.

The submarine is strongly built. Dives to 7 or 8 feet easily. 2 issues. Remote control connectivity does not work past 10 feet. does not want to go straight. always goes in circular motion no matter what button I push. Would recommend for entertainment. would not recommend for race or competition of any kind.
