building a emaxx form scratch

i was using the speed calculator and it says it would go slower with the 1/8 scale diffs.

whats going into the emaxx is 2 6xl motors, 2 4 cell lipos, 2 mm esc, i well be running 4 cells into each motor

definately go with the hybrid bulks and 1/8 buggy diffs. The stock diffs will not last with a dual 6xl system. Might I suggest using a pair of 7xl motos. It will run much cooler and you can gear it up to make up for the loss in speed. Same with the diffs, just gear up. You will have no lack of power with 2 xl motors. I see no reason that the truck will not do 60mph reliably, except with breakage due to crashes. You will also want the 3.3 upgrades such as the hubs, and driveshafts. Sounds like fun, pics are required!
