'''
This is an example builder script that sets up a quadcopter in Morse to
be driven by ArduPilot.

The quadcopter has the basic set of sensors that ArduPilot needs

To start the simulation use this:

  morse run quadcopter.py

Then connect with ArduPilot like this:

  sim_vehicle.py --model morse --console --map

This model assumes an X frame quadcopter, so you will need:

  FRAME_CLASS 1
  FRAME_TYPE 1
