I would get it from AAF. The Clark instructions are on his site, just very hard to follow. Not for beginners thats for sure. I bought 3 Taigens at the same time and the Clarks to go with them, so take your frustrations and multiply that by 3!! I think thats why alot of the vetran tankers will tell you buy a Tamiya up front for your 1st tank, plug and play and proven. I have leaned alot in the 8 months of being a tanker myself, still tons to learn! I just got a new (to me) system in a HL Tiger I,, now Im learning that board too, BARC4/TBSmini.
