• MAVLink protocol supports up to 255 vehicles in parallel and project-specific custom messages can be added
• Head-up-display, support for digital video transmission/display
• Competition-proven at IMAV and EMAV competitions (QGroundControl was used in the EMAV 2009 1st place Indoor Autonomy entry)
