In most cases you want high rpm to get the mass flow and high thrust numbers, yet you then have to have very strong blade mounts. In his case they are individually molded carbon fiber blades

250 mm and controller close to a big Jetcat in prices.
Regards,
And they cost thousands. Thrust alone isn't a good comparison. 70kg at 50kW is 1.4 g/W efficiency therefore at that level of thrust the efficiency drops to almost half that of mine (2.4g/W).
