Circuvent Drone X1

Our own airframe, our own flight stack

A 5-inch quadcopter running Circuvent's own flight stack — our attitude estimator, our control cascade, our mixer, our ESC driver. It arms only when the aircraft is level, calibrated, on a live radio link and above the battery floor, drops into a controlled descent if the radio goes quiet, and cuts power past 75 degrees of tilt. Every flight is logged to your Circuvent account with attitude, battery and timing, alongside any other aircraft you fly. Sold as a development platform: this flight stack is new, and it ships with a commissioning procedure that starts on the bench with the propellers off. Follow it in order.
