Description

The CAELUS FA1408 brushless motor is designed for pilots seeking a high-thrust, responsive powerplant for 3 to 4-inch FPV quadcopters. Its 14mm stator diameter and 3650KV rating are precisely tuned to extract maximum performance from 4S LiPo batteries, providing the punchy acceleration needed for freestyle maneuvers and the sustained power for long-range cruising.

Constructed with a focus on durability and efficiency, the motor utilizes 0.15mm Kawasaki silicon steel laminations to minimize eddy current losses and a 7075-T6 aluminum bell for an exceptional strength-to-weight ratio. The integrated premium NMB bearings contribute to smooth, low-friction rotation, enhancing both motor lifespan and flight stability. With a 115mm silicone wire lead, it offers flexible installation options for tight frame layouts.

Key Features

High-Efficiency Magnetic Circuit: 9N12P configuration with 0.15mm Kawasaki silicon steel laminations for reduced core losses and improved thermal performance.
Robust Mechanical Design: 7075-T6 aluminum motor bell provides high tensile strength and resistance to deformation under high rotational loads.
Premium Bearing Support: High-speed NMB bearings ensure smooth, low-vibration operation and extended service life.
Optimized Thrust-to-Weight: Lightweight 15.9g construction delivers a high power-to-weight ratio, crucial for agile micro and cinewhoop platforms.
Extended Connectivity: 115mm long silicone-insulated motor wires allow for flexible routing and easy soldering in constrained frame designs.
Wide Operating Envelope: Engineered for stable performance across a 44°C to 74°C temperature range under typical flight loads.

Applications

High-performance 3-inch FPV freestyle and racing quadcopters requiring rapid throttle response.
4-inch long-range or cinematic micro drones where efficient thrust and low weight are critical.
Compact Cinewhoop builds designed for agile indoor/outdoor filming with 3-inch propellers.
Lightweight micro builds utilizing 20x20mm or 25.5x25.5mm mounting patterns.

Frequently Asked Questions

What size propellers are compatible with the CAELUS FA1408 3650KV motor?

The FA1408 3650KV motor is optimized for 3-inch to 4-inch propellers on 4S LiPo batteries. Its M5 threaded shaft is standard for this prop size range. For best performance, use lightweight, high-pitch props designed for micro FPV quads to fully utilize its high KV and thrust capabilities.

What is the maximum recommended battery voltage for this motor?

This motor is designed for use with 4S LiPo batteries (14.8V nominal, 16.8V max). Exceeding this voltage, such as using a 5S or 6S pack, will significantly increase RPM, current draw, and operating temperature, risking permanent damage to the windings and magnets.

What is the mounting hole pattern for the FA1408 motor?

The FA1408 features a 12mm bolt circle diameter (PCD) with four M2 threaded mounting holes. This is a common pattern for many micro and 3-inch FPV drone frames. Ensure your frame's motor mounting plate supports this 4xM2 pattern with a 12mm PCD for a secure fit.
