Thanks in advance. I have the Y6 complete kit from 3D Robotics that I just finally got around to building. I have an APM2.6 with the external compass etc.. For some reason, I can't get all the motors to spin in test mode through the CLI. Motors 3, 4, and 5 never come online. I've checked the connections on the PDB. I've tried calibrating the ESCs. Nothing. What am I missing here?
