Gemfan 7×13 VORTEX Electric Glass Fiber Nylon Airplane/Wing/Drone Prop (2 Pcs)

Overview

The gemfan 7×13 vortex prop is a 7 inch diameter by 13 inch pitch pair built for fixed wing models and performance oriented multirotors that crave straight line speed and confident acceleration. Thanks to a glass fiber reinforced nylon blend, this set maintains stiffness under load while keeping overall weight in check. As a result, launches feel decisive, mid throttle pull is convincing, and fast passes remain stable when the power system is matched correctly.

Specs and Materials

These props use an electric grade glass fiber nylon composite that balances rigidity with impact resistance. The material choice reduces flex at higher RPM, which helps preserve effective pitch and minimizes washout in demanding maneuvers. Moreover, the molded surface finishes cleanly, so balancing takes only a few minutes and bench time stays low.

Fitment and Compatibility

A 7 by 13 profile suits park flyers, FPV wings, and light planes that benefit from a higher pitch for top end speed. 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 your maiden flight.

Performance Tuning for 7×13 Geometry

Expect firm forward bite and strong acceleration from the 13 inch pitch, especially on punch outs and long lines. For example, wings gain harder pulls out of banked turns, while lightweight airplanes track cleanly during extended level runs. If you notice high throttle oscillations, a small gyro or PID filter tweak on flight controller equipped models usually settles the airframe. Additionally, match prop load to motor Kv and battery to keep temperatures controlled and efficiency high.

Installation and Safety

Before mounting, check for molding residue and run a quick balance. Then snug the nut or collet to manufacturer specifications 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 7×13 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, the gemfan 7×13 vortex prop is a practical upgrade.
