Ditto what Jeff said. Although we have had the idea of also offering it in kit form on ebay... One way or the other though, everything will be available for you to build your own.
The parts are not FDM, they're nylon SLS. I run nylon SLS arms on my mid motor RC10 and abuse the hell of of them, no failures yet. Plenty of other people are running nylon SLS parts with very few failures. In my opinion, they are *at least* as durable as molded nylon parts.
The front diff is a Stealth diff, and as Jeff said the input and output shafts will hopefully be from Robinson.
For those who may not have seen it in the other thread, I have purchased and received a 3D printer. This will accelerate the development of this project because I can print iterations of parts quickly on it, then just rely on shapeways for final confirmation and production.
