Spy Trakr: Motors

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
10:28
10:38
10:38
overall 1:40.4

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.
