    The actual mAh capacity of a cell is affected by how much current you are pulling. For a 5000mAh pack, you might see very close to that capacity when pulling small currents, but when increased to...

    Actually, increasing voltage will increase current, and therefore wattage.

    However, a higher voltage MAY decrease glitching since the receiver circuits typically have a linear regulator to protect...

    Because if you are relying on a fan to maintain proper temps and the fan fails, the motor will overheat.

    Some reasons I can think of for rotor failure:

    - Motor rpm much too high (esp under light/no load). The centrifugal force overcomes magnet bonding material and rotor wrap.

    - Worn motor bearings...

    Sounds right. The ESC "breaks up" the battery voltage, in this case 22.2v, into pulses. The amount of time those pulses are "on" vs the amount of time those pulses are "off" (otherwise known as duty...

    Actually, what the 120A value refers to is the current ratings of the internal FETs. They can actually handle quite a bit more current in bursts too. IMO, 120A continuous is a bit unrealistic since...

    I personally think 5s is the sweet spot IMO. More speed than 4s (without overgearing to compensate for low motor rpm), and less than 6s where more failures seem to occur. Plus, at 5s, it gives the...

    Actually, if someone wants to run the MMPro, I would suggest running it on 6s, use a lower kv motor, and gear moderately. Higher power via higher voltage and lower currents, which is what you'd want...

    FYI: You aren't supposed to use a pre-charge resistor on any of the Mamba line of ESCs. It even says so on that page. ;)

    I personally wouldn't trust that loose wire. It's one of the coil wires and there are no "spares" inside, so any broken wires may cause undesirable operation if not worse. I would keep the rebuild...

    I would think launch control would have to be done via the torque-control feature of the ESC because mashing the throttle will give the same results no matter what kind of throttle curve you set.
