• 6S LiPo Battery Compatibility (22.2V) — Designed to operate on 6-cell lithium polymer batteries at 22.2 volts, this system works seamlessly with the modern battery technology that serious RC aircraft pilots in the UK already use, providing consistent power delivery throughout your flight session.
• Impressive Static Thrust Output — With approximately 3,550 grams of static thrust at peak performance drawing around 112 amps, this system delivers the raw power needed for aggressive manoeuvres, rapid climbs, and sustained high-speed flight that will transform your RC flying experience.
• Nylon Composite with Fibre Rotor Blades — The rotor blades are constructed from durable nylon composite material reinforced with fibre, providing an excellent balance between lightweight construction and robust durability, ensuring your system withstands the demands of regular high-performance flying.
• Compact Physical Dimensions — With an outer diameter of 93.8mm, a length of 85.0mm, and a total weight of just 340 grams, this EDF system integrates cleanly into purpose-built or adapted RC airframes without excessive weight penalty, maintaining the performance-to-weight ratio essential for responsive flight characteristics.
• Quick Installation in Ready-to-Build Airframes — The entire 90mm EDF system is assembled and pre-tested at the factory, allowing you to integrate it rapidly into compatible RC aircraft frames, reducing build time and ensuring you spend more time flying and less time troubleshooting.

Technical Performance

The FMS 90MM DUCTED FAN SYSTEM 12-BLADE delivers exceptional technical performance that positions it among the finest high-speed RC aircraft power systems available to UK hobbyists. The system is centred around a 3670 brushless inrunner motor with a 1950KV rating, pre-installed and factory-tested to ensure immediate reliability. Operating on 6S LiPo battery configuration (22.2 volts), the motor is engineered to achieve approximately 3,550 grams of static thrust whilst drawing approximately 112 amps at full throttle, providing the raw power necessary for sustained high-speed flight and aggressive acceleration profiles. The 90mm rotor housing incorporates a sophisticated 12-blade design that optimises air acceleration and compression, resulting in efficient thrust generation without excessive noise or vibration. The rotor blades themselves are manufactured from nylon composite material reinforced with fibre, providing a critical balance between lightweight construction—essential for maintaining overall aircraft performance—and structural durability to withstand the centrifugal forces generated during sustained high-speed operation. The entire assembly, including housing and rotor, weighs just 340 grams, ensuring minimal impact on your aircraft's weight budget. The compact physical footprint—93.8mm outer diameter and 85mm length—allows integration into purpose-designed EDF airframes or custom-adapted fuselages. FMS's attention to engineering excellence means this system delivers consistent, reliable performance flight after flight, with proper battery charging protocols and basic maintenance ensuring years of service from your investment.

Frequently Asked Questions

• What battery voltage and type does the FMS 90MM EDF system require? — This system is specifically designed for 6S LiPo (lithium polymer) battery packs operating at 22.2 volts nominal voltage. You'll need a 6S LiPo battery with sufficient capacity (typically 2200mAh to 5000mAh depending on your desired flight duration) and appropriate discharge rating (minimum 100C recommended) to safely handle the approximately 112 amps this system draws at full throttle.
• How much thrust does this 90mm EDF system produce? — The FMS 90MM DUCTED FAN SYSTEM delivers approximately 3,550 grams of static thrust at full power, making it suitable for high-speed jet aircraft, scale fighter jets, and any RC airframe designed for aggressive performance and rapid acceleration.
• Is this EDF system suitable for beginners in RC aircraft flying? — Whilst this is a high-quality component, EDF systems generally require more experience than conventional propeller-driven RC aircraft because they demand careful speed management, precision flying, and understanding of battery management. However, if you're an experienced RC pilot looking to upgrade to ducted fan power, this system is excellent. Beginners should start with traditional propeller-driven RC aircraft to build foundational skills.
• What type of ESC (electronic speed controller) do I need? — You'll require a brushless ESC rated for a minimum of 112 amps continuous output to handle this motor safely. Many experienced builders pair high-amperage ESCs (typically 120-150 amps) with appropriate programming to ensure headroom and longevity. Ensure your ESC supports 6S LiPo battery input and brushless motor operation.
• Can I use this EDF system in any RC aircraft? — No, the FMS 90MM DUCTED FAN SYSTEM is specifically designed for purpose-built EDF aircraft airframes or those adapted to accommodate 90mm ducted fan housings. The system's specifications require an airframe engineered for the 93.8mm diameter housing and compatible fuselage design. You cannot retrofit this into conventional propeller-driven airframes.
• What is the difference between this 90mm system and smaller or larger EDF options? — The 90mm size represents an excellent balance between portability, power output, and airframe design flexibility. Smaller EDFs offer reduced weight and manoeuvrability but lower absolute thrust, whilst larger systems produce more thrust but require bigger airframes. The 90mm size, producing 3,550 grams of thrust, suits a wide range of jet-style aircraft from 1-2kg flying weight.
• Is the motor pre-installed in this system? — Yes, the 3670 1950KV brushless inrunner motor comes factory-installed within the rotor assembly, so you won't need to source or install a separate motor. This saves build time and ensures perfect factory matching between motor and housing.
• What warranty and support does FMS provide? — FMS includes a 90-day warranty on electronic components from the date of delivery, plus access to long-term official technician support. This ensures you have expert assistance if issues arise and genuine support throughout your ownership experience.
