I finished assembling a f450 kit (with the e300 opto ESCs) and am trying to use a pixhawk for flight control. Everything is wired together…correctly I hope.
I was able to get the pixhawk talking to APM-Planner on my linux box, downloaded firmware for a quad, and after binding the spektrum satellite receiver, I was able to run the radio calibration.
The current issue I’m having is beeping from the e300 ESCs when I power up from my LiPo battery. They are giving what I think is the ‘abnormal input signal’ until I press the pixhawk switch. At that point the ESCs start the ‘throttle not bottomed out’ ululation. My interpretation of these codes comes from:
I was able to find this recent thread, which suggests that this issue is related to the RC_SPEED parameter:
I’ve tried several different settings for this parameter to no avail; I always get the behavior outlined above.
Does anyone have any tips? It’s highly likely I’m doing something silly, but I’m not sure what it might be.
