    well divide the number of teeth by the pitch 59/48 = 1.2" dia. That wont fit over the slipper cage.

    69 is going to be the smallest and i think u need to update to the associated slipper setup to do it.



    I think the smallest one you can use with the stock slipper is 76

    Yeah 76 is the smallest.. But 83 I think will get you a better mesh...

    @ razorback fan
    what gears you use?
    *stock 48p (slash 2wd)
    *32p / m0.8 (slash 4x4)
    *m1 (Revo)
    wich motor/esc combo ?
    bashing or speedrun?
    sand, gravel, pavement...

    for me i prever the m0.8 spur / 32p pinion combo
    spur size 54t, 56, 58t
    pinion size 11t, 12t, 13t, 14t, 15t, 16t, 17t

    58 / 17 gives lots of speed but it`s hard on the LiPo`s so short runtime
    56 / 14 or 54 / 14 is a good average setup to start
    if you bash in loose sanddunes combined with sandpaddles
    gear down 54 / 12

    I'm 99% sure he's using 48 pitch..
    He said 33 tooth pinion..

    from other post of him i found he got a VXL

    but i used this text before @ other forum, so just Ctrl C > Ctrl V here ;-)

    so theoretically 76 / 31 could work
    up to 84mph or 123.62 mph by highly unstable balooning tires

    Differential Ratio: 1
    Transmission Ratio: 2.727272727272727
    Other Ratio: 1
    Spur Tooth Count: 76
    Pinion Tooth Count: 31
    Total Voltage: 12.60
    Motor KV: 3500
    Tire Diameter (inches): 4.3
    Tire Ballooning (inches):

    Spur/Pinion Ratio: 2.45 : 1
    Total Ratio: 6.68622 : 1
    Tire Circumference (inches): 13.51 inches (343.12 mm)
    Rollout: 2.02:1
    Total Motor Speed: 44100 RPM
    Vehicle Speed: 84.37 mph (135.53 km/h)
    Effective KV Value: 3500
    ------------------
    so thats theoretically

    in real life top speed should be 10 a 15% less because of drag, resistance...
