FT recommend Flite Test C Radial or Park 400 Type, 810kV minimum , park 400 is eq. to 2212/10 1400kv (thrust:910g) or 2212/6 2200kv (thrust:732g).
FT does set the Storch to 1.8 lbs (816.46g) .. it will fly, but as other says here, youre better with some more power, for the flying and the components.
