Pete Parks has (or had) some shots up of a Sherman build-up as he worked on it...
http://www.parksoffroad.com/rcstuff/rcstuffmain.htmAs for scale comparisons... I'm hoping to get my 1/35 and 1/16 parallel build-ups further in-progress this winter, so I have matching 'display' 1/35's and R/C 1/16's for the R/C demonstrations.
I also am leaving the Leo 2A6 out of my plans, at least until I can snag a static kit for basic R/C use.
As to static Shermans & Pershings, many of us side-step the issue by buying the MF versions, strip the R/C gear out and sell it to defray the higher cost. The MF gear was never sold separately like it was for the Tiger 1 kit, so it is an easy seller on eBay at a respectable price.
