I believe Rambo used a Hoyt. I even heard that some big shot from Hoyt instructed Sylester Stallone on how to properly handle a bow. I also heard that this instructor had a small part in the film. Don't know which charactor but I think it was one of the prisoners that were rescued.

That was a long time ago, so forgive me if I'm not accurate on some of this info.

After the movie was out, I heard that Hoyt made a new model bow called the Rambo.
