Description

The CAELUS FK1806-13 brushless motor combines a high 2300KV rating with a compact 1806 stator footprint, delivering rapid acceleration and precise throttle control for FPV racing and freestyle applications. Its lightweight 23g construction minimizes overall drone mass, enhancing agility and flight time efficiency.

Engineered for durability, the motor features a robust internal structure capable of handling peak power draws up to 84.4W. The design ensures smooth, cogging-free operation across its full 2-4S voltage range, making it a versatile choice for pilots building high-performance quads from 4 to 6 inches in size.

Key Features

  • Optimized 2300KV winding for high-RPM performance on 4S power.
  • Dual mounting hole patterns (16mm and 9mm PCD) for flexible frame compatibility.
  • Precision-balanced bell and shaft for minimal vibration and smooth video feed.
  • High-grade N52SH neodymium magnets for strong torque and thermal resilience.
  • Efficient stator lamination reduces eddy current losses for cooler operation.
  • Durable 2mm hardened steel shaft resists bending in crashes.
  • Three-wire termination with high-flexibility silicone leads for reliable connections.

Applications

  • High-speed 4-inch to 6-inch FPV racing drone builds.
  • Lightweight 3-inch and 4-inch freestyle quadcopters requiring snappy throttle response.
  • Micro long-range or cinewhoop builds where a balance of power and efficiency is critical.
  • Agility-focused multirotor platforms for acrobatic flight and tight course navigation.

Frequently Asked Questions

What is the recommended ESC for the CAELUS FK1806-13 2300KV motor?

A BLHeli_S or BLHeli_32 ESC rated between 10A and 20A continuous current is recommended. Ensure the ESC firmware supports the high KV and potential RPMs this motor can reach on 4S power for optimal performance and synchronization.

What size propellers are compatible with this 2300KV motor?

This motor is optimized for 4-inch to 6-inch propellers, such as a 6020 or 5030, particularly on 3S or 4S LiPo batteries. Using larger props on higher voltages may exceed the motor's current rating, so always check amp draw with a power meter during bench testing.

Can I run this motor on a 2S LiPo battery?

Yes, the FK1806-13 is rated for 2-4S input (7.4V-15.0V). On 2S, it will spin at lower RPMs, producing less thrust but higher efficiency, making it suitable for very lightweight or endurance-focused builds where top speed is not the priority.

What are the mounting hole patterns for this motor?

This motor features two standard mounting patterns: a 16mm x 16mm hole circle (PCD) and a 9mm x 9mm hole circle. It uses M2 screws, providing compatibility with a wide range of micro and lightweight drone frames.

Package Includes
