The Gemfan Vortex 7×9E 3-Blade Reverse Rotation (PFGN7090‑3EAR) propeller set is engineered for pilots running counter-rotating twin-engine setups or reverse-mounted pusher aircraft who need maximum thrust and efficiency over standard glass-nylon props.
Important Rotation Note: This is a Reverse Rotation (R / CCW) propeller set. Unlike standard tractor propellers, these blades are pitched specifically for reverse spin to provide proper forward thrust on pusher configurations or counter-rotating twin setups (balancing torque roll when paired with PFGN7090-3EAL).
Each pack includes two matched reverse-rotation 3-blade propellers.
What sets the Vortex series apart from Gemfan’s normal propellers is its refined aerodynamic blade design and stiffer composite mix. The 3-blade Vortex configuration produces higher static thrust and smoother throttle response in tighter prop-clearance setups, while the reinforced material reduces flex at higher RPM. The result is a prop that runs quieter, tracks straighter, and delivers more consistent thrust under load.
With a 7‑inch diameter and 9‑inch pitch in a triple-blade design, the Vortex 7×9E Reverse offers aggressive pitch speed and excellent pulling power for specialised electric builds.
