Our systems


EB-Line: Our most basic system

Is in its basic design less extensive than EC- and P-Line. It’s for you who want the opportunity to experiment and complete your own system from a robust starting point

EC-Line: All-inclusive

Has the same engine as EB-Line, but with everything included. For those looking for a complete system from the propeller to the charging connector.

P-Line: P for Performance

Has the same electrical architecture as the EC-Line, but with a more powerful and advanced motor.

STAR cloud connection

EC- and P-Line come with a connection that means increased security and control over the electric propulsion.
