I have been trying for the last couple of days to get my ESCS that came preflashed with SimonK firware.
I am using a ar8000 spektrum receiver module. I can not for the life of me get the 4th beep when trying to calibrate the throttle on the ESCs with this receiver. Maybe someone out there has a bit more experience with SimonK and spektrum receivers. Any help from the community is appreciated...
