UNAV has been supplying autopilots for UAVs since 1995. The 3500 is our full-featured autopilot with an integrated camera stabilization system. The 3521 is a compact version of the 3500 that was specifically designed for small airframes (1kg). All autopilots include flight certified software, no coding, compiling or flashing required.
All hardware is fully assembled and tested, no soldering required.
