Hobbywing Platinum FW 4120SL Fixed Wing Brushless Motor 250KV/500KV/610KV

Overview

The Hobbywing Platinum FW 4120SL is a fixed wing brushless motor series offered in 250KV, 500KV, and 610KV options for fixed-wing RC aircraft applications. The series highlights double dynamic balancing to help control motor vibration, along with a propeller mount locking design and an anti-slip propeller mounting seat.

Key Features

• Double dynamic balance to control motor vibration: The rotor and the complete machine undergo dynamic balancing. The rotor dynamic balancing is completed first, then the operating conditions are simulated. A secondary dynamic balance test is performed on the motor to ensure smooth operation and eliminate any imbalance in the assembly.
• High efficiency and strong performance: The efficiency is increased by more than 2.5% compared with competing motors of the same specification.
• Efficient heat dissipation keeps the motor cooler: The rotor adopts a self cooling structure to further improve the motor’s heat dissipation performance. The continuous running time of the motor is extended by more than 30% compared with competing motors of the same specification (the running time under heavy load is longer).
• Patented propeller mount locking design: The locking design of the propeller mount has been patented. Labeled components include Reverse thread nut, Standard thread nut, and Propeller mount seat. The innovatively designed propeller mount locking system can effectively prevent the propeller from flying off due to the loose propeller mounting nut. Patent number accepted: 202311210278.7
• Diamond-shaped anti-slip propeller mounting seat: The propeller mount seat adopts a diamond-shaped anti-slip design, which effectively prevents the propeller from slipping and free spinning, making it safer and more reliable.
• Construction and materials (as stated): JNEH1200 iron core; 200C high-temperature resistant wire; N52SH strong magnetic arc-shaped magnet design; three-phase wire outlet with custom-made silicone rubber sheath; multiple rotor locking designs (copper pad, circlip, bushing set screw); optional rear shaft propeller mount support; standard titanium alloy nuts and bracket mounting screws; modular, easy-to-disassemble design for cleaning and maintenance.

Details

The Platinum 41 series fixed-wing brushless motors are offered in multiple sizes and KV ratings to match different prop and airframe setups.

The Platinum fixed-wing brushless motor is dynamically balanced in two stages to help reduce vibration during operation.

The Platinum FW 4120SL motor uses a locking propeller mount with standard and reverse thread nuts and a dedicated propeller mount seat for secure installation.

The Hobbywing Platinum 4120 brushless motor uses a modular, service-friendly design with a mounting bracket and prop adapter hardware for straightforward installation.

The Hobbywing Platinum FW 4120SL brushless motor comes with three braided phase leads and gold bullet connectors to simplify ESC wiring.

The Hobbywing Platinum fixed-wing brushless motor features a vented rotor design and pre-wired bullet connectors for straightforward installation.

The Platinum 4120 motor uses a diamond-shaped anti-slip propeller mounting seat to help keep the prop firmly seated during operation.

Test data compares maximum current and full-throttle run time (seconds) using a 6S LiPo and an APC 16x8E propeller across different motor models.
