If I select Plane in the MP Simulation, and load the parameters, the plane moves away from the Home position even before I Arm and engage Auto flight mode. Interestingly, it does not do this when I select Quadplane or Multirotor. What am I doing wrong?
in SITL the throttle output minimum is 1100 by default, this means idle, not stopped motor. So your plane is taxiing on idle. Change it to lover value, or ignore and do a takeoff.
OK, thanks! I’ll give that a try…
