    Well according to it my Slash should be going 12 - 15 mph. I don't think it's working right. I know it's going at least 25-30.

    Me too. It also tell's me that my friend's rustler with a VXL should go like 25. Trust me, its much higher. I hit myself with it at half throttle and gave myself a really nice bruise.

    Dadx2mj, that gave me a pretty inaccurate reading also.

    It told me that I would go about 22 miles an hour geared at 18/86 with a VXL. I doubt that. I can go faster with my titan and xl5.

    You all did fill in the total motor rpm's (i.e. 7,2 x 6500 = 46800) , tire diameter (2.2 inch or more/less) , 6 cell (or more) lipo OR nimh, etc.?

    Site vs real measurement by garmin nuvi 660t GPS



    right column, 47.1 km p/h


    So the site is pretty accurate i.m.o.
    my setup calculated on 53.1 real life difference about 6 km p/h or not because: this was in a street with 2 elevated crosspoints, i only had about 20 meters, cars on both sides so ride very carefully in straight line, so i guess when he realy spins up, it will get 50 km hour or even a tiny bit more. Also the original esc is still mounted also. The nimh 4000 was charged 1 hr. before but only to about 80%
    For 17t pinion and 90t spur that is good enough offroad speed for me :-) speed is power to, more speed might breaks things, that with lesser speeds wil hold.
