About the Xnova Lightning 4020 Motor


Performance & Durability

The Xnova Lightning 4020-900kV Brushless Motor with a 6mm "Type E" 30mm shaft is a high-performance outrunner motor designed specifically for 3D flying and aerial photography (AP) work in 480-600mm helicopters running on 6S systems. This motor stands out due to its superior efficiency, marked by a leading efficiency of up to 92%, which is achieved through the use of thinner stator laminations and high-performance stator metal sheets. These innovations, along with optimized ventilation and precision balancing, ensure that the motor operates smoothly, with minimal heat generation and no cogging.

The Xnova Lightning motor is built with heat-resistant materials, including specialized wires that can withstand up to 250°C and Neodym magnets that are heat-resistant up to 150°C. NMB bearings are used for exceptional reliability, and the motor is meticulously hand-wound to guarantee top-tier performance. The CNC machined parts further elevate its durability and quality. Designed to deliver consistent power, this motor is an excellent choice for pilots looking for a reliable, high-efficiency solution for demanding 3D flight and consistent power draw in professional-grade helicopters.
