    Wow... those are pretty sweet. They only run on 6v batteries. I'm sure it could be modified to run 18v to get some speed :)

    I'm interested to know how they setup the steering so that it can be...

    That makes a lot more sense now. I assume the 13 km/hr was with 18v?

    I think that furthest I'll end up going with this is 5s lipo (18.5v) and the Titan 21t motors. Going higher voltage than that...

    I just realized you said Titan 12t. I was thinking Titan 21t. The 12t is definitely a faster motor, but I wouldn't expect it to have enough torque to move a Power Wheels without burning up...

    You must have done something else to get those speeds. Both of those vehicles go 2.5mph, or 5mph if you enable "high speed" mode.

    Actually, all 3 wires are both positive and negative. Essentially, the ESC cycles through through the 3 wires, using one wire as positive another as negative, and the third is not used. It does this...

    Traxxas VXL-3s in a Power Wheels

    I was horrified to find out that Power Wheels don't have proportional throttle. It's just an on/off switch. Either full speed, or nothing. The jerkiness scared my kid and he didn't want to ride it...

    What I meant by "zero torque" was a net zero; the torque produced by the motor at that point would only be enough to maintain speed, but not overcome the friction and any other forms of internal...

    What kinds of problems? If it's stuttering/hesitation when accelerating from a low speed, that's been fixed by a recent firmware upgrade.

    Yup. Except when I'm racing, then I use the MMPro + stock motor (due to the rules for the 4x4 class where I race), and I'll even go back to the stock ESC + motor when there's a good chance of getting...

    Not quite. All else being the same, more poles does not effect the maximum torque that a motor puts out throughout a revolution. It only allows the motor to be closer to putting out maximum torque...

    Another popular combo is the MMPro + 550 size 5.5t Novak motor (HV Pro or Ballistic 550). Similar in speed to stock, but much more torque and runs cooler. You can gear it up to higher speeds on 2s...

    There's no reason to do this. Brushless motors don't need to be broken-in like brushed motors (I assume that's the reason for your statement?).
