In favor of a small operating noise we set 1,680 mm mechanics with reduction with the version for x-Treme despite rotor circle 10,2: 1. This help also the Fenestron to more number of revolutions. Please you make sure therefore with the enterprise that the permissible rotor speed of 1350 U/min. (corresponds to a Fenestrondrehzahl of approx.. 7,500 U/min.) one does not exceed. Do not let be mistaken. The low operating noise hides the actually existing numbers of revolutions!
Resulting in 7500/1350 ~5.55rpm
'Hm now I just have to find out where to connect the GV1 sensor to the Jazz80 ESC.
