The Model CR-4P is a cheap, mass-produced aircraft first designed and built by Hoover Heavy Industries but now licensed to several small manufacturing companies such as MacLeach Manufacturing. For many Skyrates it was the first plane they ever flew, but none worth his grog would stay in it long. The "Crap," as it came to be known, was about as fast and maneuverable as a rock, and saving up for a better plane is about all its pilots ever did.
