Thanks Michael. I'm an aero guy who has used 2 different commercial autopilots (MicroPilot and Atto) and am interested in the DIY world. The robust hardware of this project attracted me. I am getting more interested in controls all the time and have an aerodynamics background with a lot of experience writing code (mostly in Matlab). Hoping to find the time in the near future to become adept at microprocessors and sensor integration.
