Unlock a new dimension of flight with the Gemfan 513D, a propeller designed specifically for the incredible world of 3D FPV flying. Unlike standard propellers, the 513D features a symmetrical airfoil that allows it to generate thrust in both forward and reverse directions. This enables a properly configured FPV drone to perform mind-bending aerobatics like inverted flight, flips with zero throttle, and helicopter-style “tic-tocs.”

Unlock True 3D Aerobatic Flight

The Gemfan 513D is your ticket to defying gravity. When paired with ESCs running in 3D mode, these propellers allow your motors to change direction instantly, giving you both positive and negative thrust at your command. This opens up a whole new world of acrobatic possibilities far beyond what a standard FPV drone can achieve. It’s the ultimate tool for pilots looking to push the boundaries of freestyle.

How 3D FPV Works

Please note that 3D flight requires a specific FPV drone setup. These are not standard, drop-in replacement propellers. To use them, you will need:

ESCs that support and are flashed with a firmware that has a “3D Mode.”
Flight controller software (like Betaflight) configured for 3D operation.
Your radio throttle stick will be set up so that 50% is zero throttle, with the top half for positive thrust and the bottom half for negative (reverse) thrust.

Durable & Optimized Design

Crafted from a durable polycarbonate material, the 513D is built to handle the high stress of rapid motor direction changes. The 5.1×3.5 tri-blade design is optimized to provide good control and a responsive feel when using both positive and negative thrust, giving you confidence during complex 3D maneuvers.
