If you need a reversed servo, the 3003/4 can be reversed internally if you can handle desoldering. I have done that for an elevator servo.
Can you shed some light on this ? I need to do same so any help would be appreciated....
Tnx
This is from memory so use caution.
Remove the four screws that hold the servo together. Remove the top of the servo carefully and try to remember how the gears are installed.
In order to reverse the servo we must reverse the motor and feedback pot.
The motor and the feedback pot are soldered to the PC board (PCB). The motor is soldered on the sides of the board. The feedback pot is on the end where the wires come in. Locate these and use a desoldering tool to desolder the motor and the pot. Carefully remove the board. Remove the motor and turn it 180 degrees and reinstall. Clip the two outer leads of the pot and solder on two short insulated wires. The pot's center wire goes back in the same place. As you replace the PCB criss cross the two pot leads you soldered to the pot (route them opposite to where they originally where). Afre the PCB is back in place finish soldering the pot and the motor leads to the PCB. Reassemble and test. "GOOD LUCK"
