An RC Submarine is a submarine purchased at a toy or hobby store that is run by remote control. If you want to see a sample of an RC Submarine you can find one here: http://www.amazon.com/Swimline-RC-Submarine-27-MHz/dp/B0037M4Q3A

It's estimated that Sgt. Lee of the American Continental Army pedalled his TURTLE submarine at about 2 mph in 1776.
According to a remote control blog,the fastest rc speed boat is a C-1 boat, powered by gas, which can reach up to 200 mph. http://www.xenonproject.com/blog/worlds-fastest-rc-boat/
One may purchase kits to assemble an RC or remote controlled submarine. They are available at major toy stores or online at Amazon and Ebay. Alternatively they can be bought fully assembled at these sites.

The fastest rc boats in my opinion are the ones made by Fine Designs. These are extremely fast. I've witnessed a custom Fine Design go over 140mph. Is that fast enough for you?
The fastest way is to use compressed air to blow water out of the ballast tanks. This makes the submarine buoyant and it raises to the surface. The faster it is done the faster the sub will go up.
Fiberglass would be the only material for R/C submarines.
