Radio-controlled submarine
From Wikipedia, the free encyclopedia
A Radio Control Submarine is a submersible vessel designed to be controlled remotely by radio transmitting equipment.
The most common form are those operated by hobbyists. These can range from inexpensive toys to complex projects involving sophisticated electronics. Oceanographers and the Military also operate radio control submarines.

These models are positively buoyant, and will remain on the surface until sufficient thrust is generated over their control surfaces to force them down beneath the water.
[edit] Displacement Diving
These models have the ability to alter their displacement by taking on or pumping out water. This can be accomplished through the use of a piston, inflatable bladder, or most commonly, through a ballast tank. Boats that use a ballast tank generally fill the tank by opening a vent at the top, and force the water out by using compressed gas. There are variants that use water pumps for both processes.
