ESC calibration error in Arduplane Q-Mode VTOL

Archive Plane 4.1

I’m seeing this as well and am equally stumped on how to fix it. My setup:

  • ArduPlane 4.6.3
  • Mission Planner 1.3.83 build 1.3.9384.38258 on Debian, connected directly to the autopilot over USB
  • Mission Planner on Gentoo, connected to MAVProxy forwarding traffic to the autopilot (i.e., I’ve tried this in both a direct-connection-over-USB and via-mavproxy method with no difference in behavior)
  • Pixhawk Cube Orange w/ ADS-B in carrier board
  • Tiltrotor “quadplane” with a tri-motor setup in vectored yaw mode
    • Q_ENABLE = 1
    • Q_FRAME_CLASS = 7
    • Q_FRAME_TYPE = 1 (even though this is ignored with …_CLASS == 7)

I did manage to catch an error message in the console from Mission Planner when I clicked the “calibrate ESCs” button:

WARN MissionPlanner.MAVLinkInterface - Trying to set Param that doesnt exist ESC_CALIBRATION=3

Another post (this one) suggested setting ESC_CALIBRATION as well, so I figured I’d go do it myself – but as the MP error indicates, it’s nowhere to be found in the parameter list.
