There are many complaints about the Spy Trakr motor; all of them say it's too weak.
I opened it up to see what we were dealing with.
Four gears in the train from the motor to the wheel
Should be beefy enough, but the motor spins so slowly; the wheel does about 100 RPM.
Three wires to the motor: black, red, orange (the other wheel is green, blue, yellow)
This is a simple brushed DC motor. Orange/black power the motor and red is a ground to motor chassis.
The motor itself is a little larger than the typical guys I see at the hobby shop.
I will revisit this later to get a better idea of the motor, and how to improve the situation.
