When it comes to flight, weight and robustness is everything.
Our platform is driven by proven Digital Displacement® transmission technology, offering a solution that is significantly lighter, more robust and lower cost than an equivalent pure electric transmission. We combine this with a light aircraft, type-certified engine, enabling long endurance flight for a multitude of applications. Our hybrid platform is substantially more capable than any large drone on the market today, or in the near future.
Fly for hours, not minutes.
95kg Payload Demonstration
Our Unmanned Aerial System (UAS) has demonstrated a preliminary lifting capability of 95kg of added payload. This initial demonstration verifies our simulation models for a 160kg payload capacity.
Flight Testing with Fall Arrest
After successful initial flight demonstrations, we moved to a larger testing site with reduced flight constraints on the multicopter, enabling greater test and control development capability.
Tethered Flight Demonstration
The worlds first hydraulic-hybrid multicopter takes flight. Initial tethered testing of our ultralight hydraulic motors which are inherently robust and designed for long duty cycles in all weather conditions.
Test Cell & Flight Controller

Ground-based test bench, demonstrating propeller control and lift generation. The rig has been producing significant lift/power ratio.
Full Scale Hydraulic Motor Demo – 85kg Lift
Utilising bent-axis hydraulic motors driven with a Digital Displacement® Pump provides an ultra-light power transmission with the control bandwidth capable of multicopter attitude control. This demonstrator was capable of lifting 85kg at the propeller.
Small Scale Proof of Control Bandwidth
An initial small scale test demonstrated the feasibility of using a Digital Displacement® based transmission for control of a multicopter, where rapid and precise control is essential.
Why are we better?
Digital Displacement® Pump
A new type of hydraulic pump:
– Extremely efficient.
– Features high bandwidth control of 4 independent motors for attitude control.
– Robust: Designed for harsh environments.
– Better power to weight ratio of equivalent ‘best in class’ PM electric motor.
Proven Aircraft type certified engine for reliability, with the best power to weight ratio in its class.
– Service ceiling >7000m.
– TBO 1,200 hours.
– Liquid fuel X 20 energy to weight ratio of the best battery technology Today:
Liquid fuel: 12,000 Wh/kg
LiPO batteries 265 Wh/kg
Bent Axis Hydraulic Motors
Typical applications for such motors is indicative of their robustness.
