DroPix Flight Controller

The Drotek^® DroPix autopilot is based on the Pixhawk^®-project FMUv2 open hardware design. It runs the PX4 Flight Stack on the NuttX OS.

The DroPix system includes integrated multithreading, a Unix/Linux-like programming environment, completely new autopilot functions such as Lua scripting of missions and flight behavior, and a custom PX4 driver layer ensuring tight timing across all processes.

This flight controller is manufacturer supported.
