Technical Performance
The Spektrum SPM Brushless Inrunner Motor 0808-8800kv represents cutting-edge brushless motor engineering with its compact 0808 form factor and impressive 8-pole design. With an outstanding 8800kv rating, this motor is engineered to deliver exceptional RPM capabilities that exceed 100,000 rpm at maximum voltage, making it one of the most responsive and high-performance options available for demanding RC applications across the UK. The brushless inrunner configuration provides inherent advantages over traditional brushed designs, including zero brush wear, consistent performance throughout the motor's lifespan, and significantly reduced electromagnetic interference. The eight-pole winding configuration has been specifically engineered to minimise cogging—the tendency for motors to experience slight resistance at specific rotational positions—resulting in smoother, more linear power delivery and improved handling characteristics. The compact motor size makes it an excellent choice for lightweight applications where space is critical, from indoor electric aircraft to high-speed racing models that demand every gram of weight savings. The motor is constructed with precision-engineered copper windings and high-quality neodymium magnets that ensure consistent magnetic field strength and efficient energy conversion. As a sensorless brushless motor, the 0808-8800kv operates without internal position sensors, which reduces manufacturing complexity and cost whilst maintaining excellent performance characteristics when paired with appropriate ESC equipment. The motor's build quality reflects Spektrum's reputation as a recognised leader in RC electronics, with materials selected and manufacturing processes validated to ensure durability even under the most demanding competitive conditions.

Frequently Asked Questions
- What is the difference between an inrunner and outrunner brushless motor? — Inrunner motors, like this 0808-8800kv, have the rotor positioned inside the stator coils, making them more compact and delivering higher RPM capabilities at the expense of lower torque compared to outrunner designs. This configuration is ideal for high-speed applications where space is limited. Outrunner motors, by contrast, have the rotor on the outside and typically deliver lower RPM but higher torque, making them better suited for applications requiring strong acceleration from a standstill.
- What does the 8800kv rating mean? — The kv (kilovolt) rating indicates how many RPM the motor will turn per volt of electrical input supplied by your battery. With an 8800kv rating, this motor will spin at approximately 8,800 RPM per volt, meaning on a 3S LiPo battery delivering 11.1 volts you could expect theoretical maximum RPM around 97,680, making it an extremely high-speed motor suitable for racing and performance applications.
- What battery does the 0808-8800kv motor need? — The specific battery voltage and capacity requirements depend on your electronic speed controller and application. Generally, high-kv brushless motors like this one perform well with multi-cell LiPo batteries such as 2S or 3S packs. You should consult your ESC manufacturer's recommendations to ensure compatibility and optimal performance for your specific setup.
- What ESC do I need for this motor? — You'll need a brushless electronic speed controller compatible with brushless motors and rated for the amperage your motor will draw under load. The actual current draw depends on your application, battery voltage, and load conditions. Spektrum offers a range of brushless ESCs suitable for different power levels, and your RC Model Shop team can help you select the right one.
- Is this suitable for beginners? — This motor is best suited for experienced RC enthusiasts and builders who are comfortable selecting and integrating compatible ESCs and batteries. Because it requires separate components and careful selection of matching equipment, beginners might prefer ready-to-run RC cars UK with pre-assembled brushless systems, though this motor is excellent for those with some RC building experience.
- What does the 8-pole configuration do? — The eight poles in the stator coils create more electromagnetic interaction points with the rotor magnets, resulting in smoother acceleration, reduced cogging resistance, and better overall responsiveness compared to lower pole-count designs, which is why serious competitors and RC enthusiasts prefer higher pole configurations.
- Can I use this inrunner motor for RC aircraft? — Yes, the compact size and high RPM characteristics make the 0808-8800kv suitable for electric aircraft applications, particularly lightweight models, indoor flyers, and racing drones where space efficiency and maximum speed are priorities. However, you must ensure your ESC and battery system are suitable for aircraft use.
