Nice ! But I'd find it much more useful if it had a true three axis joystick so you could control pan, tilt, and roll all in real time. When the horizon is not level (like anytime you put side g-forces on the gimbal) it's a real pain to have to go into menus just to level the horizon. Why not just be able to twist the joystick and level it during the shot ? This is how pro systems like Cineflex, Wescam, Flir, Shotover are set up. Perhaps one like this: "http://www.robotshop.com/en/3-axis-joystick-w-button.html?gclid=EAIaIQobChMIlaC1ga_t1AIVViOBCh1s9Q3vEAQYASABEgKC6fD_BwE"
Thank you stevecassidy for your suggestion. It won't be difficult to replace current 2-axis joystick with 3-axis. I'll consider to make also 3-axis version.
As most of people don't care about roll I decided to make first version with only 2 axis.
