Took apart a Logitech Wingman Extreme Digital 3D joystick to see if I could do anything about the responsiveness of the yaw/twist control.

The piece that controls this is a pot or rheostat (please advise of the correct name) - the axis of the piece mounts to a center rod inside the joystick handle, has a nib on one end that fits into a slot in the handle structure that's responsible for rotating the piece. It seems that it only ever sees a small portion of its potential travel - wondering if I can find one that has a "quicker" response - i.e. will change the voltage more with less twist.

Any idea where to get pieces like this might be a match or close enough to be retrofitted?

Thanks.

Pot (short for potentiometer) is the correct term. Rheostat is
another name for the same thing, but that name is usually used for
high power wire-wound devices.

A source for such devices is Digikey (www.digikey.com). There are
other as well. You may also be able to achieve your desired effect by
adding some resisters in the circuit in series or parallel with the
current pot or perhaps even with no hardware changes at all by
changing something in software. It would depend on the actual design
of the joystick and its software driver. Unfortunately, I am not
familiar with either one. Good luck.
