|This is modifying the Futaba S3001 servo. This shows what needs to be
done to the servo stops. The servo pot is glued when the center is found
instead of the resistor method that other sites show.
|Either remove the inside pot slot for the output gear. You
may need to drill this out on some servos. Use Method
Number 1 for easiest adjustment.
If the slot cannot be removed, snip off the pot shaft as
shown below in Method Number 2 or use the resistor
method other sites show to take the place of the pot.
|Modify the Output Gear by
removing the limit stop piece
|Remove the stops on the inside of the servo case. This is
done just in case the output gear stop wasn't removed
cleanly. Fit the output gear back in and make that it turns
|Easiest Method Number 1 for adjusting the pot.
|Use Super glue around the pot shaft and let it dry.
NOTE: Do not get glue on the brass bushing, the ouput
gear sits on this.
|Adjust the pot shaft with the
Transmitter's sticks centered
and the trim tabs centered also
until the servo motor stops.
|Here is the servo with its pot adjusted and the glue
Re-assemble the servo at this state tempory with the
output gear to make sure everything moves freely
without any catching. If it seems okay, then add the
other gear/gears. You should be good to go.
If the servo moves slowly afterwards, use the
transmitter trim tabs to nullify the movement.
|Method Number 2.
|If you decided not to or could not remove the output gear
pot slot. I like to just snip the pot shaft off the pot.
Connect the servo electronics to the receiver and with the
transmitter sticks in the center. Adjust the servo pot until
the servo motor stops running. Move the transmitter stick
and the servo motor should start running again. Re-center
the transmitter stick and the servo motor should stop again.
Use Super glue at the pot shaft and the pot itself and let the
gue dry before re-assembling.
|MAKE sure the output gear
turns freely by inserting the
output gear back into the servo
case and turning the gear.
Also make sure the pot fits into
the output gear and the gear can
still move freely without
affecting the pot.
