[PSUBS-MAILIST] Motor Controller Tractor Beam

[Alan via Personal_Submersibles]

Jon,
I remember seeing a video where a reporter takes control in the dragon
submersible on Lake Tahoe. He throttles to go up & does what he describes
as a wheel spin & gets know where.
After some software tinkering the problem is remedied, so I presume they adjusted
the ramping time that your software can also control.

It's a little more sensitive than I care for, I think due to having 10k ohm potentiometers on the joystick.  The controller documentation recommends 1-5k ohm potentiometers but I hadn't read that far when I ordered the 10k model.  So I'll probably pick up the same joystick with 5k ohm pots and see if it feels better.
