Mateusz ,
I guess I didn't explain the issue well enough . No it doesn't fly . But, with further trouble shooting , I changed out the CC3D with a spare I have and it flies fine . ESC's do beep at power-up .
Ariele82 ,
I'll try the 50 Hz setting on the board I'm having issues with this weekend , just to see if I can still use the board or if I should just pitch it into the scrape heap .
Thanks,
Parris
