PIXHAWK compatible: Have 5 of theses on a Pixhawk controller. 2 work perfectly and 3 "bad ones" won't spin up. The three "bad ones" work perfectly everywhere else. Checked the signal voltage is 3.3 volts, the PWM pulse is 1 to 2 millisec at 400Hz. They calibrate ok. Programmed to the "factory default". Even runs fine on a pulse generator where I can vary the parameters. ANY IDEAS? Thanks

Hi guys, i got problems with this ESC, they are not saving the calibration after exit the Calib. mode. When they are inside the Calib. Mode they take perfectly the calibration and the motors run great, but when exit the mode and arm the APM they just runs like nothing happend. (Not Calibrated) I allready calibrate the 6 ESC independently and all at once, with APM and without APM My question is: is the APM capable to create this problems or is something else?...i really dont want to flash the firm to Simonk. Thanks guys

presi 2, perfetti.
ottimo regolatore al pari di quelli molto pi costosi, molto regolare l'accelerazione senza strappi o "buchi" a 20A continui con 3 celle risulta tiepido dopo 2 minuti.
perfetto, confermo 5 stelle

I use this on a 12A inrunner because the 12A blueseries couldnt handle the 3 servo's combined with the motor..
