This is a follow up to my video showing how to upgrade the Syma S33 tail rotor blade. This video shows in detail and close up how to reverse the red and black wires that go to the tail rotor motor. The wires are switched in the connector that plugs into the main board. It's necessary to reverse the wires because the new "bigger" tail blade that is installed has a pitch angle that is reversed from the stock tail blade and by reversing the wires you are reversing the polarity of the voltage going to the tail motor.
