Improvements introduced in the construction of glider helmets with internal or outboard motor, which are essentially characterized by the inclusion of two tails located at the stern, which as a longitudinal extension backwards from the edges of the edges with the flat line of the stern, isolate the working area of the motor and propeller and prevent the production of vortices that create undue vibrations.
