just noticed something!
 

Yet another example of how moronic RadioShack can be (sometimes) go to their online site and look at the stage 2 motor upgrade, you will notice that in the pic, the 2 wires going from the motor are disconnected from the black connector!

Chuckster...

Did you also notice the white, different plug on the closest motor how about how the pinions are set differently on the motor shafts.
And I still havnt figured out what those red motor plugs are exactly.

also look at the resistors and how they are not on correctly except for on the last motor

This could be a picture of some prototype motors, or just a really bad photographer.

The first three motors' pinions don't even look real.
