I bought this yesterday and these today

Plus a spray can of dunkelgelb color spray paint from a US hobby store called Hobbylinc.com, cost $20 shipped...I have an airbrush and compressor but i'd rather do the base in a rattle can rather then mixing the paint perhaps running out and having to mix another batch etc. I figure the red brown and the green will be easy enough to find even the local hobby shops have it.
Anyway, i was wondering a couple things- TRack tensioner device. A lot of people have posted how they made their own track tensioning devices but the pictures never tell the whole story of how you'd go about it.
Also is it worth while to fit roller bearings in the plastic wheels? How about just the idler wheel? And has anyone done it in a metal idler wheel?
I plan to stick with the plastic tracks, and probably the plastic wheels, to keep the weight of the model down. Will they work well with the steel sprockets?
