how to modify the default ch3 pwm out?

Posted by Ben on February 29, 2016 at 7:40am

I am building  a boat with ardurover 2.5 and bidirectional ESC. When i power on Pixhawk first , motor will run at high speed before powering RC. i have check the log file and found there is low pwm output with 1000 and think these is the problem. where i can modify the 1000 to 1500.

thanks.

      Post your parameter file.  Sound like you may have bound your receiver with a 1000 pwm failsafe but the Pixhawk is unaware that it should go into failsafe mode.
