Hey man, nice project. Not sure if you can find anything useful or not, but I put together a Takom FT a couple years back. Here's a link to the build:

I'm not as skilled as most and my attention to detail only goes so far since what I'm after is a working model in the end that looks ok from about 10 feet away. The experience I've had so far with the Takom at least is the tracks are somewhat weak and tend to lock up/jam when dirt and rocks get into them. Also, I recommend the use of a Clark TK35 as they're small than the 22 since space is really at a minimum in such a small hull.
