Check out my completed build of this submarine on my YouTube Channel here. 
 
The infamous "Wet Nellie" is a custom-built submarine, created for the 1977 James Bond film The Spy Who Loved Me in the shape of a Lotus Esprit S1 sports car. The Esprit was chosen to give James Bond a glamorous car to drive. "Wet Nellie" is named in reference to Little Nellie, an autogyro featured in the James Bond film You Only Live Twice, which was itself named after actress and comedian Nellie Wallace.

This model actually lends itself very well to RC conversion in the supplied scale of 1:8 , there is ample room for the installation of a custom watertight compartment to house motors, speed controllers, a battery, servos and a receiver.
