low end motors vs high end motors

Dunno about that, the largest sput you can get for a revo is a 40t (stock). You may be able to fit a larger modded spur but I am not sure. The revo tranny ratio is different, that is why the spurs are smaller than the emaxx. Both the revo and emaxx have the same diff ratios. An emaxx can have a pretty high ratio, especially with 32p gears. Like 10/72 would be 7.2/1 ration, where a revo may fit 10/40 : 4/1 ratio. Use briang's calc to figure out the various ratios for the tranny.

The Revo tranny is much more flexible as far as gearing goes. There are not really any clearance issues as the motor does not lay next to the tranny. Also, don't forget that the 2nd gear ratio is changable. Put in the narrow ratio and you can get a very high FDR (over 20:1) Top spd will suck tho.
I thought MGT spurs fit as well, but they are not really needed regardless.

Fine Design sells a large line of LMTs now, including the 1940s and 1950s. The 1950s are ~$50 more than a Neu 1515, but it would work w/ the MM. They are excellent motors tho. He's kinda of an ass, but he's the only game in the US for LMT motors. I've ordered a couple things ferom him in the past w/o issue, but some have had problems.
