    Gearing with XERUN 150A & 2200KV Motor

    HI,

    I have a question about the gearing ratio on my new brushless SUMMIT.

    I have recently buy a combo XERUN 150A & 2200KV Motor and i would know what is the best gearing ratio for this combo.

    I run with 2 Traxxas Lipo 7.4V 7600 MH.

    I don't want reach high speed but just a little higher than summit stock speed.

    Well right now I'm using a 68 tooth spur and a 14 tooth pinion. The acceleration is really quick but top speed is about 30-40mph and I'm happy with it for now. Jamann I think is running a 58 spur and I think a 13 or 14 pinion and it's the same. Runs quick but not stupid fast.

    LOL I ran a 2560KV with a 20T and it went 50MPH. So fast, you never need full throttle, accept for doing rolling wheelies back to back. It sounds like you would like the stock gearing. Pinions are cheap and easy to swap, so I'd give the stock a try while you order a 13T and a 15T. Make sure you get the right pitch.
    PM me for help converting your Summit to brushless

    stock gearing will work well. Run that and watch temps, if you want more out of it you should be able to get it but stock gears will perform very well.

    ola pessoal ,tenho algumas duvidas?
    tenho uma summit com esc/motor xerun 150a ,o motor esta esquentando bem!
    qual é a temperatura normal do motor ?
    qual é a temperatura máxima que o motor pode chegar?
    quais baterias devo usar (exemplo: 2 bateria 2s 5800mah 30c )

    uso bateria de 5800mah 30c !mais não esta aguentando o summit, o esc esta cortando a energia apos 5minuto ?

    What he is asking:


    hello guys, I have some questions?
    I have a summit with esc / motor xerun 150a, the engine is warming up nicely!
    what is the normal engine temperature?
    what is the maximum temperature that the engine can reach?
    which batteries I use (example: 2 battery 5800mAh 2s 30c)

    use battery 5800mAh 30c! most enduring is not the summit, this esc cutting power after 5 minutes?
    MAN, Use Common Sense
