EFT-Hybrid-1x

The EFT-Hybrid-1x is a revolutionary hybrid-electric powertrain for long-endurance multicopter UAVs.

It enables platforms of up to 75kg to achieve an endurance of more than 5 hours.

The hybrid powertrain was designed and developed by EFT Mobility in 3 product generations and is now fully integrated into a UAV package from initial pilot customers.

It demonstrated the capability of EFT Mobility to execute System Architecture, Design, Integration & Validation of complex new powertrain systems.
