This is a hobby I only recently gotten into (just over a month), and loving it! I currently own only two tanks but waiting on a third. I'm also currently installing metal arms for one and repainting the next. As for other mods that I had thought of doing eg fans, etc, I've decided to leave as much of it as stock but just installing splash/dust shields for light mud and water action and changing detaills like the tiger barrel (rotated but not extended yet).
Originally, my idea was to get introduced to this new hobby but it has taken up most of my attention and time

Which is an absolute blast, and nothing major has malfuntioned so its a bonus! My dogs loves chasing my rc buggy but they run when those tanks fire up![sm=devious.gif] I must stress however, its the sound they're not sure of, and not from getting shot at ...

From a safe distance, they just look at it deviously hehe.
For me, my next move will be towards the 1/8 tanks. I originally wanted to move to Tammy's but I might as well just go 1/8 from a cost effective view.
After that, I'm not sure. Most likely I will try to build one from sctratch like yours. At the moment I enjoying repairing, but not motivated enough to scratch build
