Cobra 4120/22 Brushless Motor Summary

Cobra 4120/22 Brushless Motor

COBRA 4120 is a high efficiency and high torque brushless motor. It is made with super hardened neodymium-iron-boron magnets, high temperature and high purity oxygen-free copper wires, as well as 0.2 mm laminations. Plus its perfect full-trough rate and flat shape, COBRA 4120 motor offers maximum efficiency and minimum Eddy Current losses.

The integrally formed component made of CNC aviation aluminum ensures its super high precision. It has a 5.0mm shaft for extra strength, as well as two oversize ball bearings to support the shaft, which provide a perfect dynamic balance and a long life. 

Ultra-flexible motor leads with high-temp silicone rubber insulation and 3.5mm bullet connectors already installed embody the humanization of Cobra product, and simplify your installation process.

Although 4120 motor only weighs 293 grams, it can drive a Fixed-Wing aircraft with takeoff weight about 4.5KGs.
