I wonder how many parameters in arducopter,

and how to check it.

About 1200, but only 300 are required to be configured for proper operation.

Load a default vehicle in Mission Planner’s Simulator.

How to count parameters on default vehicle?

There is no clue on the answer.

Thanks for amilcarlucas’s answers.

Load a tune, then click “save parameters” in Mission Planner. Open the saved file with a text editor (like Notepad++) and count the lines.

This doesn’t show the parameters that are only visible after you enable stuff though, like IMU temp cal for example.
