Attopilot
From Dronepedia
The Attopilot is a commercial, closed-source, but hobbyist-developed autopilot system created by RCGroups user 'icebear', Dean Goedde. The company developed to create the autopilot board and code, Attopilot LLC, works with a spinoff, Attopilot International, which markets the autopilot and half a dozen airframes to go with it. The project's store sells a number of notable hobbyist and semi-professional-grade UAV platforms.
