    48p to 32p equivalent

    hi guys I'm back

    I wanted to know in a quick and simple answer, if i could (a) get a 86t 32p plastic spur gear, or (b) get one of you guys to give me an equivalent setup. I run on a 2s 5000mah lipo and a 3800kv castle motor in my Slash 2wd. Basically, I stripped my spur gear, and I was running 23t/86t with 48p gears and they stripped. I want to have the same performance as I had before, but I want to use 32p for the bigger teeth. I want the spur to be plastic, obviously because i don't want transmission problems.

    Thx

    P.S. I already have a 20t 32p pinion on hand, so if i could get the same performance as the 23/86 48p setup using that gear, that would be convenient.

    14/58 should be close to 23/86.

    here you go, with pictures... Note your gear cover won't fit

    and I did this last week as I found a bag of 32p 1/8 shaft pinions

    Hot Racing sells a metal 32p gear that will work with the cover

    what caused your spur to strip in the first place? generally, they don't strip unless of improper setup or mechanical failure of something else

    yes, plastic is what you should use, metal is all bad... ends up being a bandaid for improper setup, and requires expensive, hardened pinions

    I have used both traxxas, robinsons and asscociated 32p pinions, have had great results with the first two and no the cover will not fit, however because of the strenght and size of the gears most obstacles and pebbles will be chewed; make sure kids fingures and yours do not end up there too.

    The 48p gears are graeta and smooth , more precise gearing but since I have a mojory of my rigs as 1/8 system I changed all mine.

    Also, for quick on-the-fly conversions between 48p and 32p you can just use a short conversion formula:

    Tooth count divided by current pitch, multiplied by the new pitch equals the new tooth count.

    In an example from 48 to 32 should be

    86t / 48p = 1.791666666666667

    1.791666666666667 X 32p = 57.33t

    The equation works both ways. I usually use it at the lhs when making purchasing decisions on the fly
