Lumenier RX1407 3800KV Motor

Lumenier brushless multirotor motors were designed to give you top of the line performance and value for your RC models. This Lumenier RX1407 3800Kv motor has been engineered from the ground up, and it is the perfect blend of elegant design and high end performance. By using high quality bearings and CNC precision machined parts, each Lumenier motor provides silky smooth, reliable power.

This micro sized, high Kv motor is designed for small aircraft running 3" to 4" propellers.

The Lumenier RX1407 3800Kv motors have a strong 2mm internal shaft which has been machine pressed into the upper bell of the motor. No longer is there a need for micro sized 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 also included with each motor ensuring your propellers do not come loose during flight. Each motor comes with 4x M2x5 screws for mounting on most airframes. The motor wire length is 100mm, precut and tinned to make for easy installation on most micro builds where space is tight.
