I am also planning to use an Arduino based controller setup with KSP. My first goal is just to add a few frequently used controls, and remap controls of my XBOX 360 controller in flight using the USB Host Shield. So I am definitely interested in this. Some of my ideas: - deadzone control so no manual deadzone adjustment is necessary - use a rotary encoder to adjust controller sensitivity - use a motorized pot for throttle (so it can be set to min/max with a button and also controlled from the controller)
