    Spur and pinion

    Hi,



    1. Just wondering if these pinions also works with the ERBE, like some old timer here setup 21/54. My friends had these and gave it to me for free, just want to make sure it works ok for my ERBE. Planning to run this with 54 spur/4s.





    2. What is your advice on the motor (Mamba Monster) temp? To what extend should I stop and let it cool before hitting it again?

    Thanks.

    are you calling me an old timer??......................ha

    .8 mod 21T Pinion Gear with 5mm Bore (32 pitch)

    A temp gun is kind of a must have.....
    Hot motor + cool esc = under geared.
    Cool motor + hot esc = over geared
    Everything warm just right..

    Motor ~ 180/190*F (82/88*C) maximum, ideally 140/160*F (60/71*C), temps can be 10*F higher inside the motor
    ESC ~ pretty much same temps / Fan comes on @ 150*F (65*C)
    The new MM2 fan runs non stop, also should be taken off when driving in wet conditions.
    Lipo's ~ 140*F (60*C) max, ideally 100/120*F (38/49*C).........
    Would you go flip my truck back over??

    Haha. Old timer? Not that old timer old timer I meant, experienced and helpful dude in this forum that what I meant.

    Yeah, you did advices that on my other thread. It's just,

    I don't have these pinions in my hand yet, I'm not sure it's 5mm bore, but 32 pitch for sure. Might be this weekend.

    What does .8 mod means?

    Guess if these not fit mine, I'll buy the one you suggested.

    Thanks old timer

    .8 mod is the same as 32 pitch, it is just metric.
