Technical Performance
The FMS 90MM Metal Ducted Fan represents a significant engineering achievement in RC aircraft propulsion systems. The 90mm diameter specification provides an optimal size for medium to high-performance RC aircraft applications, offering substantial thrust potential while remaining manageable in terms of weight and power consumption. The metal construction throughout the fan housing and blade assembly ensures exceptional structural integrity, maintaining precise blade geometry even under the extreme conditions of high-speed flight. The 12-blade design creates a pressure-optimised airflow pattern that generates smooth, consistent thrust with minimal turbulence or vibration—factors that directly impact flight stability and overall aircraft control authority. This ducted fan system is engineered to work seamlessly with a variety of motor options, allowing builders to fine-tune performance characteristics to match their specific aircraft requirements. The metal-to-metal construction ensures excellent electromagnetic shielding and thermal management, critical considerations for reliable operation of brushless motors in high-demand applications. Whether you're building a sleek electric jet-style RC aircraft or a high-speed racer, this fan provides the foundation for reliable, efficient thrust generation. The construction quality reflects FMS Hobby's reputation for precision manufacturing and attention to detail—factors that translate directly to longer component lifespan and superior in-flight reliability.

Frequently Asked Questions
- What motor should I use with the FMS 90MM Metal Ducted Fan? — Motor selection depends entirely on your aircraft design and desired performance characteristics. You should consult the aircraft plans or specifications for your build project to determine the appropriate motor size and KV rating. FMS provides comprehensive documentation for their aircraft kits, which typically include motor recommendations. When selecting a motor, consider your intended use—whether you're prioritising speed, efficiency, or balanced performance—and ensure the motor's power output matches your ESC rating and battery capacity.
- Is this ducted fan suitable for RC beginners? — This component is best suited to experienced RC aircraft builders and pilots who have prior experience with RC aircraft construction and operation. Building an aircraft around a ducted fan system requires intermediate to advanced building skills, including motor installation, ESC programming, and careful weight management. If you're new to RC aircraft, we recommend starting with a ready-to-run or almost-ready-to-fly (ARF) aircraft before progressing to building custom configurations with individual components.
- What makes a metal ducted fan better than plastic alternatives? — Metal construction offers several significant advantages over plastic ducted fans. Metal dissipates heat more effectively, crucial for sustained high-performance operation. The material provides superior structural rigidity, meaning the fan maintains precise blade geometry under stress and vibration, resulting in more consistent thrust and better flight characteristics. Metal fans also typically offer longer lifespan and better resistance to thermal stress from high-powered motors.
- What aircraft designs can use the FMS 90MM Metal Ducted Fan? — This 90mm fan is compatible with various RC aircraft designs, particularly medium to high-performance electric jets, fast trainers, and performance-oriented RC aircraft. Common applications include ducted fan RC jets, high-speed composite aircraft, and custom performance builds. You'll need to verify compatibility with your specific aircraft design and ensure the fan fits within your fuselage envelope.
- How do I install this ducted fan? — Installation involves mounting the fan assembly into your aircraft fuselage, selecting and installing an appropriate motor, connecting an ESC, and programming your speed controller. Specific installation instructions depend on your aircraft design. FMS Hobby provides detailed manuals for their aircraft kits that include step-by-step installation guidance. If you're building a custom application, you'll need intermediate mechanical and electrical knowledge to ensure proper installation and safe operation.
- What power source is suitable for this fan? — LiPo battery packs are the standard choice for electric RC aircraft with ducted fan systems. The specific battery capacity, voltage (cell count), and C-rating depend on your motor selection and desired flight duration. A typical configuration might use a 3S, 4S, or 5S LiPo pack, but this must align with your motor's voltage rating and your ESC's maximum input voltage.
