Default Reversing a Servo

Can anyone tell me how I can reverse a servo without using my transmitter?

Default Reversing Servos

It is very straight forward. When you open up your servo you will see the potentiometer. Reverse the two outer wires but leave the center wire alone. Next, reverse the wires that are soldered to the motor and you are done. This is easier on some servos than others. Thanks!

On many (if not most) modern servos wires are no longer used to the motor (they're a source of failure). The servo is constructed so that the motor and its terminals are soldered directly to the servo controller board. I don't think I would attempt to reverse that type of servo.

They require a bit more caution, but are not much more difficult.

Cut the traces leading to the motor, and solder two jumper wires across them. The same for the potentiometer if it's soldered directly to the circuit board.

On the Futaba 3004, I unsoldered the motor from the board and turned the motor 180 degrees. Reversed the outer pot leads and resoldered the motor.

That'll work too - if the design allows it.

Offcourse, some may not want to torture there servo.

Instead, you can build a servo reverser, which is't any bigger than a post stamp. Check it out here:
