RE: Servo Reversing
Good thing I know how to solder. I reverse servos as a matter of course at least with Hitec HS-425BB. Just follow the diagram Chasint provided and reverse the wires to the motor and the outside wires to the pot. Use small diameter shrink tubing to provide vibration protection. That and don't over solder getting the solder up underneath the wire covering creates a joint that's prone to failure. A good joint should be bright and shiny.
If you don't know how to solder I would not recommend you do this.
