Welcome to Hydrospace Models.

Since 1990 Hydrospace Models has been designing and building high-speed  maneuverable submersibles.  The ORCA, or Original Radio Controlled Aquaplane, is the result of over 10 years of research and development in hull design and control systems.

Capable of virtually all maneuvers performed by full scale aerobatic aircraft, the ORCA is both highly maneuverable and fast.  With a wingspan of only 20 inches, the ORCA can be “flown” in the smallest of swimming pools.
