In the vertical axis, only here's a video made by Jeffery Chan http://myweb.hinet.net/home17/highto/tank-1.wmv right click to download the video to your hard drive and play, the sound track is messed up.

Have you tried BYA for the GBS http://www.backyardarmor.com/New%20Main.htm just scroll down till you see Tamiya Tanks and you'll see it listed off to the right.
