Gemfan 7×5 VORTEX Electric Glass Fiber Nylon Airplane/Wing/Drone Prop (2 Pcs)

Overview of gemfan 7×5 vortex prop

The gemfan 7×5 vortex prop is a versatile 7 inch diameter by 5 inch pitch set engineered for fixed-wing models and small multirotors that need dependable thrust and predictable handling. Thanks to its glass fiber reinforced nylon blend, this two-piece pack offers an excellent strength to weight ratio while maintaining smooth tracking at higher RPM. Consequently, pilots can expect confident launches, clean acceleration, and efficient cruise speeds without excessive amp draw.

Specs and Materials

These props use an electric-grade glass fiber nylon composite that balances rigidity with impact resistance. The material reduces flex under load, which helps preserve effective pitch at speed. In addition, the molded surface finishes cleanly, so balancing is quick and bench time stays low.

Fitment and Compatibility

The 7×5 size suits park flyers, FPV wings, and light planes that call for a 7 inch diameter with moderate pitch. With the appropriate shaft adapters or collets, installation is straightforward on common electric motors. Always confirm rotation direction, ground clearance, and canopy or duct spacing before a maiden flight.

Performance Tuning for 7×5 Geometry

Expect lively throttle response with firm forward bite from the 5 inch pitch. For example, wings gain harder pulls out of banked turns, while lightweight airplanes track cleanly during fast passes. If high-throttle oscillations appear, a small gyro or PID filter tweak on FC-equipped models typically settles the airframe. Additionally, matching prop load to motor Kv keeps temperatures controlled and preserves battery life.

Installation and Safety

Before mounting, check for molding residue and run a quick balance. Then snug the nut or collet to manufacturer specs and recheck after the first pack. Furthermore, keep hands clear during bench tests, power up with props off when configuring electronics, and wear eye protection during installs.

Durability and Care

Reinforced nylon handles routine grass landings and minor scuffs well. Nevertheless, inspect blade roots after rough arrivals and retire any prop that shows deep nicks or stress whitening. A light wipe with isopropyl alcohol keeps the finish clean and reduces grime buildup near the hub. Therefore, longevity improves and vibration stays low.

Who It Is For

Builders chasing efficient speed on park flyers, FPV wings, or small drones will appreciate this balanced 7×5 option. It rewards pilots who want crisp throttle feel, straightforward setup, and dependable materials without extra weight. For simple performance gains without reworking the airframe, this VORTEX pair is a practical upgrade.
