Not quite sure what you are asking for... Pololu makes great inexpensive motor controllers that would work perfect with GM8's... check out http://www.pololu.com/products/pololu/0410/

Yes, but you need a driver for each motor. Some drivers, such as at dimensionengineering.com, are dual.

Also try servocity.com and look for ESC.

The Pololu Dual Serial Motor Controller enables independent control of speed and direction for each of two motors.  That is, at the same time, you can run the left motor clockwise at one speed and the right one counterclockwise at a different speed.

How many amps would your motors draw?

Perhaps a L298 is what you want?

Use a multimeter or power supply that measures current :P

Well , if its 40 amps at 120V i think you should see a doctor ,lol    ;D  no just kidding , you'd be dead by now


Perhaps its time to invest in a new multimeter ?
Check out the Roboduino, Arduino-compatible board!

lol . . .

I believe you have a clamp on amp meter, which uses magnetic fields to measure the current on dangerous high powered wiring. I suspect its just measuring noise . . . or you are Magneto from X-men . . .

Go to radioshack and buy a $15 multimeter :P
