Description

The CAELUS FA1204 2500KV brushless motor utilizes a 9N12P framework with a 12x4mm stator, engineered for stable and responsive throttle control in micro FPV applications. Its construction prioritizes low vibration and thermal management, enabling consistent power delivery for freestyle, cinematic, and long-duration cruising flights.

Designed with precise PWM tuning (900–2100 µs), the motor maintains excellent efficiency across its operational current range, peaking at 48W of power. The 2.0mm shaft diameter and robust bearing system ensure reliable performance, making it a core component for high-performance micro drone builds.

Key Features

  • High-efficiency 2500KV design optimized for smooth, low-vibration micro-drone flight.
  • Lightweight 6g structure with a durable 7075-T6 aluminum bell for strength without added mass.
  • Premium NSK bearings minimize rotational friction and enhance long-term durability.
  • 0.15mm Kawasaki silicon-steel stator laminations reduce eddy current losses for improved thermal and electrical efficiency.
  • Broad 2S–4S LiPo voltage compatibility supports versatile build configurations.
  • Stable performance profile specifically matched for 2–3 inch propellers.
  • Precise PWM input range (900–2100 µs) allows for accurate throttle calibration and control.
  • Optimized thermal design for low-temperature operation under sustained loads.

Applications

  • High-performance 2-inch toothpick-style FPV racing and freestyle drones.
  • 3-inch micro-long-range or cinematic cruising quadcopters.
  • Lightweight 2S-powered micro whoop or tiny trainer builds.
  • Compact 3-inch CineWhoop platforms for smooth aerial footage.
  • Agile micro FPV drones requiring a high thrust-to-weight ratio.

Frequently Asked Questions

What size propellers and drones is the CAELUS FA1204 2500KV motor designed for?

The FA1204 2500KV motor is optimized for 2-inch to 3-inch micro-class FPV drones. It delivers stable and efficient performance with propellers typically sized for these frames, such as bi-blade or tri-blade props in the 2–3 inch range, making it ideal for toothpick racers, micro long-range, and CineWhoop builds.

What is the compatible voltage range for this motor?

This motor is designed for use with 2S to 4S LiPo batteries. Its 2500KV rating provides a balanced thrust curve across this voltage spectrum, allowing pilots to tailor their build for aggressive freestyle on higher voltages or efficient, longer flight times on lower cell counts.

What are the key mounting specifications for the FA1204 motor?

The motor features a 15.7mm diameter bell and uses a 9mm PCD (bolt circle diameter) mounting pattern with four M2 threaded holes. This compact mounting scheme is standard for many micro and whoop-style flight controller and frame stacks, ensuring easy integration into lightweight builds.

How does the motor's construction contribute to its performance and durability?

Performance is enhanced by the 7075-T6 aluminum bell for lightweight strength, NSK bearings for smooth rotation and longevity, and 0.15mm Kawasaki silicon-steel laminations in the stator for high electromagnetic efficiency and thermal stability. This combination results in low vibration, consistent power delivery, and reliable operation.
