Hardware in the loop simulation for arducopter has been around for a few months already, but it usually requires you to find a quad-copter model for xplane to use yourself, It is not the prettiest model but it gets the job done. I have attached a decent model of a quad-copter for xplane, along with the parameters (thanks to Jean-Louis) for anyone to easily get started with arducopter hardware in the loop simulation. Allowing you to test arducopter out in a safe virtual environment. The file can be downloaded below (Xplane-quad.zip).
