Fly Ramrod, the ultimate Spaceship from the Cavallery Supreme Command from the 80s animated TV show "Saber Rider and the Star Sheriffs".
The show is Japanese and originally called "Sei Jyushi Bismark".
The spaceship transforms into a huge fighting robot-cowboy. Of course, this add-on is far off from beeing realistic (and doesn't look as cool as the animated one) but it is fun flying it.
Works with Orbiter Build 031217 and the 030115 Spacecraft.dll
