Tom, pls correct me if I'm wrong, but it appears that 1/6 scale is the more popular of the larger scale tanks.

My only reservation with 1/6 (aside from the price) is that they're too heavy to lift. Even my 1/8 weighs somewhere around 70 lbs, so I've built a ramp to drive it onto/off of a workbench.

Check out RC Armory's web site www.rcarmory.com to get an idea of their product line in 1/8.

Cheers...
