Caelus Motor Starry 5315 achieves extreme lightweighting and efficiency while providing huge torque. It represents the cutting-edge development direction of multi-rotor/electric vertical take-off and landing power systems: high performance, high power density, and lightweighting. With a weight of 323g, it has been elevated from the category of industrial basic components to that of high-tech competition components. It does not serve ordinary commercial transportation, but rather serves as a cutting-edge project aimed at competing for technological supremacy and challenging performance limits.
