At just £43.99, this brushless motor offers outstanding value for money, making it an accessible upgrade path for both experienced RC flyers and those new to brushless RC technology who want to understand how motor selection impacts flight characteristics and overall performance.

FMS motors are engineered to work seamlessly within complete RC aircraft systems, and this 3648 KV770 unit maintains that tradition of quality and compatibility. The motor's specifications have been carefully chosen to deliver the sweet spot between power delivery, efficiency and heat management during extended RC flights. If you're serious about getting the best performance from your RC model, this motor belongs in your parts collection.

Key Features

• 3648 Motor Size — The 3648 designation refers to the motor's physical dimensions, which are standardised across the RC industry to ensure compatibility with a wide range of RC aircraft frames and motor mounts, making this a versatile choice for builders with existing RC setups.
• KV770 Rating — The 770 KV rating indicates the motor's rotational speed per volt applied, meaning this motor delivers moderate-to-high RPM output that balances power delivery with efficiency, making it suitable for cruise flying and moderate-to-high-speed RC aircraft applications without sacrificing battery life.
• Long Shaft Configuration — The extended shaft length provides greater flexibility in motor mounting orientation and allows for easier integration into diverse RC aircraft designs, whether you're building scale warbirds, sport planes or custom RC aeroplanes.
• Brushless Technology — Brushless motors eliminate the maintenance requirements of traditional brushed designs, offering superior efficiency, cooler running temperatures during extended RC flights, and significantly longer operational lifespan compared to brushed alternatives commonly used in older RC models.
• FMS Quality Engineering — As an official FMS component, this motor benefits from rigorous testing and quality control standards that ensure reliable performance across countless RC flights, backed by FMS's reputation for producing high-quality RC aircraft and systems.

Technical Performance

The FMS 3648 KV770 Motor represents a carefully engineered balance of performance characteristics designed for RC aircraft applications. The 3648 motor size is a proven platform within the RC hobby, offering a compact footprint whilst delivering sufficient power output to drive propellers across a wide range of RC aeroplanes, from lightweight foam designs to more substantial scale models like the FMS P47. The 770 KV specification means that for every volt of electrical potential applied to the motor, it will rotate at approximately 770 revolutions per minute under no-load conditions—this moderate KV rating is particularly well-suited to aircraft that require sustained, efficient power delivery rather than explosive acceleration. The brushless design eliminates carbon brush wear entirely, meaning you'll experience consistent performance over hundreds of RC flights without the gradual performance degradation seen in brushed RC motors. Heat dissipation is superior to brushed alternatives, allowing extended flight sessions without thermal throttling. Build quality reflects FMS's commitment to precision engineering, with tight tolerances and quality materials throughout the motor's construction. The long shaft design accommodates various mounting configurations and propeller adaptor arrangements, giving you the flexibility to integrate this motor into bespoke RC aircraft builds or as a replacement component in existing FMS designs.

Frequently Asked Questions

• What is the KV rating and what does it mean for my RC aircraft? — The KV770 rating indicates that the motor will spin at approximately 770 RPM per volt of input. This moderate-to-high KV rating is designed to provide good balance between power and efficiency for RC aircraft applications, making it suitable for a range of plane types from sport flyers to scale models. Higher KV motors spin faster but deliver lower torque, whilst lower KV motors spin slower with higher torque—the 770 rating sits in a sweet spot for most RC aircraft hobbyists.
• Is this motor suitable for beginners to RC flying? — Yes, this FMS motor is an excellent choice for those new to brushless RC aircraft systems. The 3648 KV770 is a forgiving, reliable platform that won't punish piloting mistakes, and brushless technology is far easier to maintain than older brushed RC motors, making it ideal for RC enthusiasts learning the fundamentals of electric RC flight.
• What type of RC aircraft can I use this motor with? — The 3648 KV770 is particularly well-suited to RC aeroplanes in the light-to-medium power range, including sport flyers, trainers, and scale models like warbirds. It's compatible with the FMS P47 and many other FMS RC aircraft designs, though you should verify compatibility with your specific airframe to ensure proper power-to-weight ratio.
• What battery type does this motor require? — The 3648 KV770 motor is compatible with standard lithium polymer (LiPo) batteries commonly used in RC aircraft, though specific battery capacity and cell count recommendations depend on your aircraft's weight, power requirements and desired flight time. You should consult your aircraft's manual or documentation for optimal battery specifications.
• What is the difference between this and other FMS motors? — FMS manufactures motors across a range of sizes and KV ratings to suit different RC aircraft applications. The 3648 KV770 represents a specific balance of size, power output and rotational speed; other FMS motors at different KV ratings or sizes would be optimised for different performance characteristics, flight styles or aircraft types. Choose based on your aircraft's specifications and desired flight performance.
