Dear Guys, in our analysis of a flight failure, using the Pixhawk, we see that the ardupilot software gave the right commands to the ESC/motors combination. However, it seems that these commands (PWM signals) were not giving the proper result to the ESC/motors (X80 hobbywing with only grnd and signal wire).
So one question is how long the normal PWM signal wire can be without losing the signal strength (in meters or feet)? We used shielded wire in this test for the signal cable, however the shield was not connected to the ground (we later understood it should).
Can anyone of the Px cube developers tell us how long cable can be max to ensure proper signal at the end. And what can be done to extend that length? Should we add a 5V on the rail of the motor outlets just like for the aux channels?
Hope to hear, Winfried
