    Brushed to brushless

    Hello, I have a emaxx and it is wayyy to slow and the brushed motors fry too fast and I want a motor that is more satisfying so ive settled on buying a mamba monster 2. I was wondering what upgrades my emaxx needs to be transformed from brushed to brushless. Or is it fine as it is?

    It should be fine as is......until you break something then I'd just replace the broke part.

    Depends on which Maxx you have...
    Whatever it is I just typed... could be wrong.

    I just got my mm2 all I did was switch the motor plate and cover. Been running 4s and haven't broke another yet. The switch is great. I highly recommend. Make sure you have decent lipos. Get at least 30c or more

    I'm not a lipo expert but I believe its the amount of amperage released from the battery at once. If you read the castle drivers ed book the explain it better then me. I have onyx 5000mah 25c and I experience little bit of lag when I punch the throttle on my mm2 and 2200kv motor.

    The C rating is the amount of discharge the higher the C rating the more punch it has when pulling power from the battery.

    Punch is relative to more than just C rating. For instance... a 2200mAh 25C battery has less punch than a 7600mAh 25C battery. Punch comes from the batteries ability to keep up with amperage demand. Here is the formula to figure out what any LiPo battery is capable of delivering:

    To calculate the constant discharge rate of your pack
    mAh x minimum discharge C rate / 1,000 = available amps
    For example lets use a 2200mah 20-40C pack.
    2,200 x 20 / 1000 = 44
    This battery pack can consistently provide up to 44 amps.

    Using that formula, the 2200mAh 25C battery is capable of providing up to 55 amps continuously and the 7600mAh 25C battery is capable of providing up to 190 amps continuously. See how a higher C rating is not always relevant? Even if the 2200mAh battery had a 50C rating it would only be capable of 110 continuous amps.

    So, in other words to find the real difference between a 25C and a 35C battery we would also need to know the capacity of the pack.
    Whatever it is I just typed... could be wrong.

    That's why you should always go for the highest C rating and capacity pack that:
    a) will fit in the vehicle it's going into
    b) you can afford

    Will a traxxas 2s 5000 be good enough?

    You can get much better batteries for much less money than the traxxas ones. Shop around.
