Key Features

• 460kV Brushless Motor Design — The 460kV rating determines the motor's speed characteristics, providing the ideal RPM output when paired with appropriate battery and propeller combinations for large-scale warbird applications, ensuring efficient power delivery without excessive current draw.
• 14-Pole Configuration — The 14-pole construction contributes to smooth, consistent power delivery and balanced performance across the flight envelope, which is essential for maintaining stable control in a 1.5-metre scale aircraft during sustained flight operations.
• Brushless Technology — Unlike brushed motors, brushless design eliminates carbon brush wear and maintenance requirements, extends motor lifespan significantly, reduces heat generation and improves overall efficiency, meaning more flight time between servicing and greater reliability in demanding applications.
• P-51D 1.5m Mustang Compatibility — This motor is purpose-designed for the P-51D 1.5m Mustang platform, ensuring optimal performance, correct fit and maximum compatibility with the aircraft's power system architecture and mechanical design.
• Spektrum Quality Assurance — As an official Spektrum accessory, this motor meets rigorous quality standards and is backed by the manufacturer's reputation for reliability and customer support, giving you confidence in your investment.

Technical Performance

This brushless motor represents serious engineering for large-scale RC aeroplane applications. The 460kV specification means the motor will rotate approximately 460 times per volt supplied, making it ideal for medium-speed to high-speed flight regimes typical of 1.5-metre scale warbirds like the P-51D Mustang. The 14-pole stator configuration ensures smooth commutation and balanced force delivery throughout the motor's operating range, eliminating the vibration and inefficiencies often found in lower-pole-count designs. Brushless motors of this class are constructed with high-quality stator windings, precision-machined bell housings and balanced rotors, delivering superior performance characteristics compared to brushed alternatives. The elimination of brushes and commutators means zero arcing, minimal electrical noise and significantly extended operational lifespan. For 1.5-metre scale RC aeroplanes, this motor class provides the torque needed for reliable takeoffs and sustained flight while maintaining the efficiency required for respectable flight duration. The motor's thermal characteristics are optimised for continuous operation, with proper cooling airflow through the aircraft's fuselage ensuring stable temperature management during extended flights. Whether you're operating from grass fields across the UK or at established RC flying clubs, this motor's performance envelope is matched to serious recreational and competitive warbird flying.

Frequently Asked Questions

• Is this brushless motor suitable for my P-51D 1.5m Mustang RC aeroplane? — Yes, this motor is specifically engineered for the P-51D 1.5m Mustang platform. Spektrum designed this motor to match the power requirements and mechanical specifications of this aircraft, ensuring optimal performance, proper fit and reliable operation. If you own this aircraft and need a replacement or upgrade motor, this is the authorised choice.
• What are the advantages of a brushless motor compared to brushed alternatives? — Brushless motors eliminate carbon brushes that wear over time, requiring no maintenance in that regard. They run cooler and more efficiently, converting more electrical power into useful thrust. They produce less electrical noise and vibration, deliver longer operational lifespan and offer superior power-to-weight ratios, making them the standard choice for serious RC aeroplane enthusiasts across the UK and worldwide.
• What battery and ESC compatibility should I consider? — The source documentation does not specify exact battery cell count (2S, 3S, 4S etc) or ESC current rating compatibility. You should consult the P-51D 1.5m Mustang manual or contact RC Model Shop for guidance on battery selection and electronic speed controller compatibility to ensure safe operation and optimal performance.
• How does the 460kV rating affect flight performance? — The 460kV rating influences how fast the motor spins per volt of battery power. Lower KV ratings spin slower but with more torque; higher KV ratings spin faster with less torque. At 460kV, this motor is positioned for medium to high-speed flight applications typical of 1.5-metre scale warbirds, delivering a balanced power characteristic that provides responsive control whilst maintaining reasonable power efficiency.
• Is this motor available in UK stock? — RC Model Shop is an authorised Spektrum retailer. We recommend checking product availability by visiting our website or contacting our Walsall store directly, as stock levels may vary. Our experienced team can confirm current availability and provide guidance on delivery timeframes.
