High-Pitch, Seven-Inch Props for Compatible FPV Builds
The Gemfan Vortex 7x13x3 is a three-blade FPV propeller with a 7-inch diameter, 13-inch nominal pitch and 5mm center bore. Choose a two-pack of clockwise or counterclockwise props to match your motor layout.
Keep the correct rotation on hand for your build rather than buying a mixed pack you do not need. Each option contains two props of the same rotation; a single pack is not a complete mixed-rotation quad set.
Choose Your Rotation
- 2CW: Two clockwise propellers.
- 2CCW: Two counterclockwise propellers.
Check the manufacturer's rotation markings and your aircraft's motor-direction configuration before installation.

- Maximum listed blade width: 20.5mm.

Build Compatibility
The high nominal pitch requires careful matching to motor KV, battery voltage and ESC capacity. Confirm the motor manufacturer's propeller recommendations and test current draw and temperatures in a controlled setup. A 5mm bore alone does not establish fit: also check shaft engagement, retaining hardware, hub thickness and frame clearance.
The original description associates the propeller with high-speed FPV use and mentions a 3kg takeoff weight without identifying the aircraft, motor, voltage or test conditions. That figure is not a verified payload capacity or a guarantee that these props can safely fly a 3kg aircraft. No verified thrust table, maximum RPM or comparative performance data is provided here.
Perfect For
Experienced FPV builders selecting high-pitch seven-inch tri-blade propellers for an appropriately rated propulsion system, or replacing props with the correct rotation on a compatible build.
What's Included
Two Gemfan Vortex 7x13x3 gray propellers in the selected rotation: either two CW or two CCW. Motors, aircraft and mounting hardware are not listed as included.
Installation and Safety
- Disconnect power before fitting or removing propellers.
- Confirm propeller rotation, motor direction and retaining-hardware fit.
- Keep people and loose items clear of the propeller arc.
- Replace cracked, bent, chipped or otherwise damaged props; do not rely on a durability claim after an impact.
- Remove propellers during electronic configuration and motor-direction testing.
