: I remember reading somthing about the joysticks going to 254 but the motors maxing out at around 158. can anyone tell me where to find this post or confirm the number for me? I looked through the archives but was unable to find it. Thanks

. Depending on your joysticks you may not be able to get the full number (the controller is counting a time related to you joystick's resistance). Most joystick pots (the sensing element) have all the resistance in a patch at the centre, and when you get to, say 3/4 of the way to max position, the resistance stops changing.
If your element is low resistance, you may not reach 254. If your element or the wiper going to it is not great, you may never reach 0.

. I just tested the Blue Victor I have here, which I don't think has been recalibrated (see below) and I found that the output was nil from 127 to 137 (written into a test program), and then changed in linear fashion up to 218, approximately, at which point it was full on (not switching).

. Perhaps what you really want to know is that by using the calibration switch on the Victor you can change the response, somewhat, from the factory setting. Read the Victor Information .pdf from InnoFirst.

. Hope this helps.
