watertight cylinders
Watertight cylinders (or WTC's as they are often called) are the heart and soul of an R/C submarine. Their main functions are to keep the electronics and battery of your boat dry during operation and to create a means of increasing or decreasing the buoyancy of the model through the use of a ballast system.
