I can tell you right now without running those gear's that they will wear very fast. Alum on alum gear's ~ no go. The idler's should either be steel or coated/ heat treated to withstand the wear. If you put alum on alum in a tranny and use a big brushless motor it will wear, fast. There is a reason why Ultramaxxed coated their idler's. if the rc4wd gear's are in fact wear-proof like the ultramaxxed i'll take my word's back.

No company is going to make expensive gear's for an out dated truck only a few brushless guy's would run. And with the slipperantial coming up, nobody will run a tranny in the future. Atleast that's how I see it.
