    14.4 Dewalt Speed runs/test (E-revo and E-maxx)

    I just thought I would share my speed results with the 14.4 Dewalt motor in an emaxx and erevo.
    Any thoughts/questions are welcome.
    Both trucks were tested on dry pavement in 30 degree Fahrenheit weather.

    E-revo.

    -Completely stock E-revo 5603 except for a kershaw designs motor mount and the dewalt motor.
    -Long travel rockers and summit springs
    -62t spur and 24t pinion. 2.58

    *-25mph using 25c 5000mah lipos
    -motor temps stayed +-55 degrees

    E-maxx

    -Stock except for traxxas cvd center driveshaft, integy heatsink fan, and kershaw designs motor mount and dewalt motor.
    -big bore shocks and integy green progressive springs
    -68t spur and 25t pinion. 2.70

    *-30 mph using 25c 5000mah lipos
    -motor temps stayed +-55 degrees

    Blue E-revo
    Pink E-Maxx

    Good research!

    I worked up to a 28T pinion with the stock 68T spur with my DeWalt. I got around 27-28mph but it was with smaller tires. Unfortunately the ESC didn't like the 28T pinion once I drove it off road. The temps shot up so high the thermal protection kicked in.

    Now I've settled in to a 22T pinion with a 72T spur. Temps are really low and it has lots of torque with good speeds. I think around 22 or 23 mph.

    cool, i run 28T 64T but in the old maxx off road. There's a few different dewalt 14.4V new style motors with different power ratings. I should have them bookmarked somewhere. I think most or 99% of people use the 396505-21 because that's what the first person to do the mod used, so every followed because it worked and was a big improvement.

    Thanks!

    Hmm, your old gearing is close to mine now, I'll have to watch the temps when I go offroad, thanks for the heads up.

    I didn't know you could fit a 72 spur? Thanks for that too lol

    That is some high gearing! What kind of speed did you get? Any heat issues?
