Hummingbird 0702 True 30000kv RaceSpec AC Motors - (Set of 4) Hummingbird 0702 30000KV RaceSpec Brushless AC Motors are designed for high-speed Whoop racing and deliver 30000KV real power for extreme speed and performance. Each motor weighs just 1.29g per motor, including straight heat shrink enamel leads, making them some of the lightest available on the market. NewBeeDrone is the first company to use straight enameled wires for direct soldering to the ESC, reducing weight and increasing efficiency - ideal for high-speed racing where every gram counts. These engines are specially designed for 1S race setups and offer precise performance. For maximum life, we recommend pairing the Hummingbird 0702 motors with NewBeeDrone Smoov Lube Motor Bearing Oil, which helps reduce friction and wear and keeps the motors in top condition. NOTICE: This motor is for our Hummingbird V3.1 RaceSpec BNF and is not recommended for use on other helicopters due to the very high KV rating. 30000KV is very high even for racing applications and can easily cause damage to batteries, ESCs and the motors themselves. This product is intended only for experienced pilots who fully understand the risks associated with high KV engines. Unlike most of our products, returns will not be accepted on this motor and we are not responsible for any damage these motors cause to yourself or other components you choose to use them with. NOTICE: Each phase of the motor consists of two enamelled conductors. Be careful not to mix up the wires from different phases as this can cause the motor to burn out. Specifications: The motor is equipped with an electric motor, which is designed to power the motors: Model: Hummingbird 0702 RaceSpec KV: 30000KV Power: 1S Shaft diameter: 1 mm Cable length: 25 mm Enameled wire straight Weight: 1.29g per motor including heat shrink enamelled wire The package contains: 4x Hummingbird 0702 True 30000kv RaceSpec motors
