Overview
The HGLRC SPECTER 2306.5-1900KV brushless motor is designed for 5-inch freestyle and 5-inch racing drone builds. It uses a 7075 integrated rotor with a two-color anodizing process, N52H arc-shaped magnetic steel, 260° high temperature resistant copper wire winding, and a low-loss stator made with Kawasaki silicon steel sheets for stable operation and efficiency.
Key Features
- Brand new rotor appearance design; anodizing two-color process
- 7075 high strength integrated (one-piece) rotor
- Customized high-performance N52H arc-shaped magnetic steel for stronger magnetism and higher efficiency
- 260-degree ultra-high temperature resistant copper wire winding to support continuous high-throttle flight stability
- Imported low-loss silicon steel sheet stator to reduce heat generation and loss
- Optimized tuning: high torque at low speed, linear power output during rapid throttle changes, quick and precise response in sharp turns
- Titanium alloy shaft to increase strength and reduce drone weight

Details

Built for 5-inch freestyle and racing builds, the SPECTER 2306.5 delivers responsive power on 5–6S setups.

A 7075 one-piece rotor with a two-color anodized finish adds strength while keeping the motor looking clean.

N52H arc-shaped magnetic steel is used to boost magnet strength and improve overall efficiency.

High-temperature copper wire winding is designed to stay stable during extended high-throttle flight.

The low-loss stator core helps reduce heat generation and keeps performance consistent through a full pack.

Motor tuning focuses on low-speed torque and linear throttle feel for precise control in fast direction changes.

The compact 2306.5 size fits common 16×16 M3 mounts used on many 5-inch FPV frames.

Multiple angles show the open bell design, mounting base, and clean winding layout.


Key specs at a glance: 1900KV, up to 47.7A and 1145W, rated for 5–6S with a 20AWG 150mm lead.


Weight comes in at about 34.2g including the wire for a balanced 5-inch build.



In the box: one motor, an M5 anti-loosening nut, and five M3×8mm mounting screws.
