Hybrid propulsion system for Unmanned Aerial Vehicles. We also offer the possibility to customize the power and autonomy among other variables. Equipments can be modified custom-fitting the needs of the client.


  • Increase in the flight ceiling
  • Greater power for short take-offs
  • Increase in the rate of promotion
  • Noise reduction during stealth missions
  • Up to 60 horsepower increase
  • Elimination of the thermal footprint


Add up to 40CV (30Kw) of combustion engine extras for short take-offs, high ascent ratios or compensation of the main engine power loss during the hottest months.


Increases flight safety, allowing for 202 minutes of continuous flying in the event of combustion engine failure so that the airplane can land in a safe place or return to the aerodrome in case of failure during takeoff.


Además de la recarga en tierra. Durante el tiempo en el que el Sistema híbrido AX-40U no se usa, regenera las baterías para que estén siempre cargadas al 100%.


The AX-40U adds the fully electric operation function to the aircraft without the need to start the gasoline engine. A fully electric ground-roping operation reduces fuel consumption and maintenance of the gasoline engine.

The amount of energy stored in the battery equals four liters of gasoline, which can be charged on ground for very little money (less than € 0.5). In total, the energy stored in the battery is equivalent to € 5 in gasoline with a real cost of € 0.5. The use of this energy in flight is equivalent to a saving of € 4.5 per flight.


All the technology has been developed exclusively for aeronautics. The product has successfully passed a team qualification process that includes analysis, laboratory testing and flight testing.

The AX-40U product is certified in Spain and is in the process of obtaining European certification.


The AX-40U is fully compatible with Fixed Pitch Propellers and Controllable Pitch Propellers.

1 The maximum power can be adjusted according to the needs of the client up to a maximum of 55 hp. To calculate the actual performance of the electric motor compared to a combustion engine, according to the tests performed, a 40 hp electric engine is equal to a 60hp combustion engine.
The flight time depends on the aerodynamic efficiency of the plane.
