Re: Making a 5k joystick work

Once again, are you sure? This is merely speculation, but I would think that the circuitry would detect when the current flow through a particular potentiometer is below .05mA (5V / 100kohm), so it would know when the joystick is unplugged. A 5k pot would draw more current, and I can't imagine that the circuitry is designed to send a signal of 127 to the RC when there is most definitely something plugged into the port. I wouldn't be surprised if a 250k pot didn't work, but a 5k? I disbelieve.
