Well it is unfortunate, but I can only assume that the process is complicated getting the physics correct, but I really have no idea.

About the only thing you can do is take an existing model, get it close to the correct size and get the power equipment dialied in. Lastly repaint it to look like what you want. It is far from ideal.

It would make sense from a marketing perspective to put out the Horizon models in the sim, but I'm guessing there's some snag preventing them from doing this.
