    Of course you can create more torque. Thats gearing. However you cannot create more power.

    Since power = torque * RPM, then with gearing you can increase torque gearing, but you lose RPM (of the...

    If you subscribe only to theoretical physics:

    torque = force = voltage.

    Deg of Rotation = distance = current

    Power = work = watts.

    Only put holes in your tires (2, at opposite sides of the tire) if you are going to be spending considerable time in the water.

    If not, only put holes in the wheels.

    And to also be fair, a "spike" is much harder on the ESC, *regardless of the battery attached to it*, than it is on the battery. And you dont have a current spike, per se. You have a power spike. ...

    I'm really not trying to be a jerk here, but what do you think you are measuring when you measure the "resistance" of a pack of batteries? I think it's a great deal more complicated than that.
