I bought the motors and escs from bluerobotics some time ago and built a bathymetric survey boat. Everything works fine, but the only problem is that I have never been able to reverse in manual mode with the remote control. I checked the pixhawk parameters on SERVO1 and SERVO3 and they are correctly MIN=1100, TRIM=1500 and MAX=1900. The remote control, with the stick all the way down sends 1100, halfway 1500 and at maximum 1900. The problem is that with 1100 (stick all the way down) the motors are stopped, they are not all the way back. With the stick halfway (1500 the value sent), the motors power is at 50% and with the stick all the way forward we are at maximum forward. Theoretically the ESCs do not need to be calibrated… what can I do to activate reverse?
You also need to set the RC inputs.
Assuming you’re using RC Channel 3 for throttle, you will need to set the RC3_TRIM value to 1500.
