The output gear I have is form rc4wd- they stopped making them just after I got mine, so no idea on the quality of the metal, but its aluminum at any rate- If I found some proper Ultramaxxed gears for sale... I doubt I would buy them anyway because they are so expensive, lol.
Tranny is lubed every half a dozen sessions or so- there was still a fair amount on the gears when I dismantled it, so its not wear caused by lack of lube or what-not.
The stock gears didnt work well for me at all, the teeth either sheered off or just ground down very quicky- delrin of softer plastic might last a bit longer (self lubing plastic...), but I doubt muchlonger; they are actually hard to find in the UK, very few places have many parts for the old emaxx tranny, or if they do they arent actually very cheap- too much hassle swapping it out half way through a run.
What I really need to do is build a CD unit something like the Candyman has, unless Mike starts cranking them out shortly.
As for lighter wheels and tires, I has a suprize in store....
