Hobbywing PLATINUM 2603 1480KV 1800KV Brushless Motor for 2S 3S F3P Indoor RC Plane

Overview

The Hobbywing PLATINUM 2603SL Brushless Motor is an ultra-light 18g power system built for 80g300g F3P indoor competition aircraft and other lightweight fixed-wing models with strict weight limits. With a compact 30 H16.2 mm motor size, 12-slot/14-pole design, and a smooth, linear throttle response when paired with the Platinum 18A V5 F3P ESC, it is designed to help pilots execute precise, high-difficulty aerobatic maneuvers. In the mid-to-rear load range, motor efficiency and maximum thrust increase by over 5% versus similar-spec motors, reducing power anxiety and improving competition performance.

Key Features

• Ultra-light design: motor weight 18g (including wires) for weight-critical F3P builds

• High-performance electromagnetic materials:

  • 0.2mm silicon steel laminations for strong torque and efficiency

  • 220C high-temperature enameled wire for reliability under load

  • N52SH high-strength arc magnets for high torque density

• Multi-strand winding: improves slot fill, helping reduce operating temperature at the same power output

• Low vibration, stable flight: rotor dynamic balance standard 5 mg for smoother control and cleaner aerobatics

• Efficient cooling + weight reduction: large hollow rotor frame and stator base design supports continuous heat dissipation during aggressive flights

• Fast prop installation: rotor frame integrates a propeller mounting structure for quick assembly/disassembly

• Flexible mounting: elliptical mounting-hole design supports 4 2.1 @ D33 and is intended to fit common F3P airframes

• Durable hardware: 630ZZ bearings, titanium alloy shaft material, and 500V AC insulation withstand test
