Thank you Dan.

. A lot of options out there. Just checked them out, pretty impressive. And I see they are working on a 1/6 version, which when I am caught up on my other 1/16 projects I want to dive into 1/6 and scratch build one. I can't comment on the rx-18 because I have not had one yet, I am thick headed and can't get past that cam style elevation, if there was a way to by-pass that I would gladly purchase your set up.
Cheers,
Wade
