E-70b2 EFI Engine

Ideal for UAVs of MTOW from 20 to 65 kg. The seamless combination of the in-house developed electronic control system and the unique mechanical design gives the E70b2 engine high power density and guarantees the durability and reliability of the propulsion system. Compared to the earlier generation of engines, the 15%-25% lower fuel consumption allows the UAV to cover longer mission range. The compact mechanical design facilitates the integration into the airframe with limited space.
