Simulator for Mission Planner always gives message "not Armable"

ArduCopter

I am trying to use the arducopter Mission Planner 1.3.77 simulator
, but I always get the message Pre arm: mode not armable . The stabilize mode is set before I click arm and the plan is installed and on the map.
Arming checks are disabled.

I am able to actually fly the plan on a real quad, but not on the simulator.

Do not disable the arming checks. Fix whatever problem you have instead

Thanks Amilcarlucas. I changed arm checks to “all” and still have the same “not armable” message. I am not sure why arm checks are important for a simulator.

Can you post a .bin log? Maybe we can get more details out of that .

Is this what you mean by .bin log?

After the 1st Arm and Takeoff command it’s now in Auto mode which can’t be armed be default. Change the auto_options parameter to change this.

Thanks Dave I made auto_options change and can take off. But the simulator quad goes into wild gyrations and I get the message “compass variance”. Don’t forget this is in the simulator, not a real flight.
I have tried takeoff with 0 compass , 1 compass, and 3 compasses enabled without success.

Dave, I solved the wild flight condition by setting compass to defaults. and changing the auto_option to 7. The simulator works perfectly. Many thanks.
