Lumenier RX2204-14 2300Kv Motor By using high quality bearings and CNC precision machined parts, each Lumenier motor provides silky smooth, reliable power. The Lumenier RX2204-14 2300Kv motors have a strong 3mm internal shaft which has been machine pressed into the upper bell of the motor. No longer is there a need for set screws that loosen over time. The motor features an integrated 5mm threaded prop adapter allowing you to directly mount the propeller to the motor without the need of a separate prop adapter, saving you weight. An ultra-lightweight, black anodized, low profile, flanged aluminum lock nut is included with each motor ensuring your propellers do not come loose during flight. Each motor comes with 4x M3x5 socket cap screws for mounting on most airframes. The motor wire length is 100mm and includes pre-soldered male 2mm bullet connectors for easy installation. Wires can also be cut and soldered directly to your ESC.
