SO I finished it the other day, ran like a bat out of hell. I have some bald tires I use for concrete, turns out this thing has a little too much power, or the Raze was cheap for a reason... Like I said above I am not too worried about the life of this buggy so... Live and learn. I already ordered the upgraded steel helical diff rings and pinions for this and the rear diff, figured I would do both since this will most likely just reoccur in the rear next time I fire her up. Pretty fun though, geared pretty lightly and she screams on a straight with 4s. I like the set up, runs cool, and I haven't even added the motor heatsink/fan that was included yet.
