Not your average Emaxx build

[RC-Monster Mike]

The diffs look like Hot bodies Lightning units - used quite a few of them over the years. The tranny gears are likely hard stainless, which is not typically very magnetic. Titanium would be a poor choice for tranny gears IMO(doesn't wear well). The idlers look like UE, but every UE idler I ever saw was black oxide coated hardenend steel. The Ultramaxx idlers were brass IIRC. Funny thing, though - I have an idler just like that(looks like a silver UE idler) that I got from a customer probably 10 years ago(Aussie fellow) - I don't recall the maker, but I kept it along with one of my idlers(I made hardened idlers for a few years after UE stopped making them, but mine had a radial groove instead of the holes).
Cool craftmanship on the Maxx, too - looking forward to watch this develop into a complete rig.
