Freespace Callisto 50 Multirotor

The Callisto 50 has world leading performance with up to 25 kg payload capacity while maintaining single propulsion fault tolerance in the event of a propeller out failure (up to 50 kg TOW). Flight endurance on lithium batteries can exceed 40 mins with <5 kg payload allowance (refer to performance graph for details). A series hybrid petrol-electric ICE range extender & ground power tether system are available to increase flight endurance significantly. (see separate details) Ideally suited for heavy lift operations, slung tether payloads, LiDAR surveying, scientific instrument payloads, BVLOS operations and more. The Callisto 50 has full autonomous BVLOS mission capability via ArduPilot autopilot system with long range comms, telemetry & other advanced features.

The Callisto 50 has been granted CASA Type Rating Approval for standard and tethered operations. Freespace Operations offers full support Australia wide including p projects, custom payload integration, mission planning, consultation, training, maintenance, and more.


The Callisto 50 is a VTOL multirotor allowing take-off and landing from any suitable platform providing sufficient minimal clearance is available (at least 1 aircraft width each side of the propeller tips). It’s dynamic stability allows operations in 15 – 25 m/s winds up 1500 m above sea level. Flight Modes The Callisto 50 offers 3 basic flight control configurations: – Remote Pilot manual control with multiple autopilot assisted flight modes. – Full autonomous flight modes following internal waypoint navigation. (typical BVLOS scenario) – “Guided Mode” flying where the aircraft is commanded via an external source (eg. Onboard companion computer / server such as a Raspberry Pi with custom navigation software). The flight modes can be changed in real time while the aircraft is flying.
