Gemfan D2.8-3 Cinewhoop Propeller

Product Overview

The Gemfan D2.8-3 is a high-performance cinewhoop propeller designed for 2.8-inch ducted FPV drones. Constructed from durable PC (polycarbonate), it features a 71.12 mm diameter and 2.8-inch pitch, delivering strong thrust output, stable flight control, and efficient aerodynamic performance.

Optimized for the DJI O4 HD video transmission system, the D2.8-3 adopts an advanced aerodynamic blade profile that supports both normal and inverted mounting configurations. Built under strict dynamic balance control standards, it significantly reduces vibration and ensures a smoother, more stable flight experience for cinematic FPV applications.
