Details

CubeMars GL80 is a GL-series hollow-shaft motor built for stabilized payloads, with smooth low-cogging performance and efficient operation.

A 30 mm hollow shaft makes it easy to route signal and power wiring through the motor for cleaner gimbal and pod builds.

At only 315 g, the GL80 helps keep handheld gimbals and compact pods light without sacrificing control stability.

An IP45 rating adds extra protection against dust and water splashes for more confident use across varied operating scenes.

Follow the installation drawing and avoid overly long screws to prevent internal damage during mounting.
