DarwinFPV 4320 350KV Brushless Motor for 13-15in X-Class FPV Drones, 12S 48V, NSK Bearings

Overview

The DarwinFPV 4320 350KV brushless motor is designed for 1315 inch X-Class FPV racing drones, and can also be used on aerial photography multirotors or fixed-wing aircraft that require heavier payload capability.

Key Features

• Japanese NSK bearings for smooth, silent operation and impact durability.
• Customized N52H high-temperature-resistant arc-shaped magnets for stronger magnetic force and increased pulling power.
• Multi-strand winding for higher slot fill factor, stated to deliver 4% longer flight time compared to single-strand motors.
• Dual-security fixation using circlips and countersunk screws at the bottom for a sturdier, more impact-resistant shaft.
• M6 stainless steel shaft compatible with most propeller mounting holes available in the market.
