sheet. The initial electric motor employed was the Rotex RE X907 of at 330 volts. In 2014 the design was upgraded with a Rotex RE BB 90-5, a brushless, DC, liquid cooled powerplant that produces at 3,000 rpm and weighs . It is controlled by a MGM Compro HBC-Series V7, 300400/EPOS1 controller with a maximum continuous current of 300 amperes and a maximum supply voltage of 400 volts. The batteries are Kokam Company, Ltd. SLPB100216216H cells, with 45 cells connected in series, producing 378 volts. In February 2017 the company still described the design as "under development".
