Subject: Calibrating joystick Poly800

From: ultragalore@...

I have a problem with the Poly after my HAWK800 / atomahawk kit. The joystick DCO seemed to be miscalibrated. I need to pull it half an inch down to have proper center value.

For those who are fiddling with this also, I managed to calibrate the Y-axis by putting a 50K variable resistor between pin 16 an 5 on the IC6 analog multiplexer IC:

Grit on Twitter: "Finally managed to kill the @comtruise DCO drift on my #poly800 with this 50K resistor. Ehrm... is this a good thing? http://t.co/Gqh63Dp7N9"
