Overview
The Hobbywing PLATINUM 2604SL Brushless Motor is a lightweight, high-efficiency power solution for 80g–300g F3P indoor competition aircraft and other ultra-light fixed-wing models with strict weight requirements. When paired with the Platinum 18A V5 F3P ESC, it delivers precise, linear throttle response for accurate, repeatable aerobatic maneuvers. In the mid-to-rear load range, the motor’s efficiency and maximum thrust improve by over 5% versus similar-spec motors, helping you fly with more confidence and stronger competition performance.
Key Features
-
Lightweight class for F3P builds: approx. 21.5g (including leads) for weight-sensitive aircraft
-
Smooth and stable output: rotor dynamic balance ≤ 5 mg reduces vibration and improves control precision
-
Stronger performance under load: efficiency and max thrust +5% in the mid-to-rear load range for more effortless flight
-
High-grade electromagnetic materials:
-
0.2mm silicon steel laminations
-
220°C high-temperature enameled wire
-
N52SH high-strength arc magnets
-
-
Multi-strand winding: improves slot fill to help reduce motor temperature at the same output power
-
Efficient cooling + weight reduction: large hollow rotor frame and stator base design supports continuous heat dissipation during aggressive flights
-
Quick prop handling: integrated propeller mounting structure for faster installation and removal
-
Wide mounting compatibility: elliptical mounting-hole design supports common 4 × 2.1mm patterns on D32/D33 F3P airframes
