Rand, I've seen the Shooters chassis online. But I'm not sure how thick it is. My Yok's SSG chassis is 2mm thick. Yok also sells a 1.9mm and 2.1mm chassis. I think I saw them on R10. The 12L3 is about 2.2mm. Go for the Yok if you really like it. It handles good. And can be made to handle better with a few hopups. Only thing about my carpet setup on the Yok was I ran Tamiya front springs. And I have NO clue what rate they are!
Anyways, I have pics of my RugRat. I'll post it in a second. On mine, I have the servo back instead of forward like most others. Later on I'll try the servo more forward. But I can't seem to get the ball cups right when I have the servo forward. Well let me get the pics...
