CR Flight develop innovative counter-rotating propulsion systems to provide greater efficiency, thrust and longevity for vertical take-off and landing (VTOL), multirotor and horizontal-flight unmanned aircraft (UAVs and drones).

eVector Propulsion Technology by CR Flight

Electric propulsion for UAV and drone propellers

eVector, the patented contra-rotational technology developed by CR Flight, significantly enhances thrust efficiency and overall performance of propeller systems powered by an electric motor.

US-made counter-rotating drone motors

Benefits of our Innovative UAV Propulsion Technology

When compared to conventional electric motors, the Electric Propulsion Units (EPU) with eVector technology deliver:

  • 30 – 50% greater thrust efficiency
  • Up to 100% increased operating range
  • Quieter operation with lower noise
  • Zero emissions

Proven performance enhancements

This performance comparison chart shows how the operational thrust generated by the eVector EPU compares over a range of amps to a conventional electric motor. Notice how the eVector EPU performs for a longer continuous operation.
