Dualsky CRS3000 MKIII Contra-Rotating Propulsion System – Precision F3A Power Unit
This listing covers two CRS3000 MKIII variants, allowing users to select the configuration best suited to their electrical setup and propulsion requirements while benefiting from the same proven system architecture.
Series: CRS3000 MKIII
Available Variants:
CRS3000.13 MKIII
Optimised for specific voltage and propeller configurations commonly used in precision F3A setups requiring refined throttle control and efficiency.
CRS3000.16 MKIII
Optimised for alternative voltage and propeller combinations, offering flexibility for different propulsion tuning requirements within the same CRS3000 MKIII platform.
The Dualsky CRS3000 MKIII Contra-Rotating Propulsion System is a high-efficiency electric propulsion solution engineered for applications demanding torque-neutral operation, aerodynamic stability, and precise power control. Built around Dualsky’s advanced contra-rotating architecture, the CRS3000 MKIII drives dual counter-rotating propellers from a single integrated brushless motor system, significantly reducing rotational torque while improving thrust utilisation and directional stability.
Developed for FAI F3A competition aircraft, this propulsion system delivers smooth, linear throttle response and predictable power delivery, making it ideal for precision aerobatic platforms where consistency and control are critical. The contra-rotating design enhances airflow symmetry, allowing pilots and system designers to achieve refined flight characteristics across the entire throttle range.
Beyond competitive RC aviation, the CRS3000 MKIII platform is equally suited to engineering research, propulsion system development, academic studies, UAV experimentation, and laboratory environments where balanced thrust systems and controlled torque behaviour are required. Its system-level design makes it particularly valuable for aerodynamic testing, efficiency optimisation, and experimental propulsion applications.
