I agree. Even with the UltraMaxx gearset I dont think the tranny will stand the power of a kilo and a half weighed motor. Not to mention that two motors are supposed to be used. With such a setup the maxx will be in the mid 100 mph easily and even more.

And good luck trying to control it! Even in the 50mph range is quick, 100? Bye bye truck, i dont think there would be enough room to even top out!

Nay. Guess I'll forget about speed runs from now on. I'll only make my ultimate speed run with my Evo lV and that's it, no more speed runs....well, not really.

Im good friends with Microwebtech (aka..Dan) the person behind the making og the Ultramaxxed gear set. And he told me just recently that the Gen III gear sets are out of production and no longer will be made by him..due to cost and the shop that made them for him is closing it's doors. I actually have a set of Gen II gears( that I'm running in my emaxx still) with no problems to date, but I also have a set of gen III just in case they fail. So I'm holding onto these. They might be overkill but atleast I don't have to worry about hte tranny failing (just my .02 worth) any ways some say they are worth it others say they are not....personal preferance I guess.....but if you run across a set...they probably will be worth some money due to out of production....
