This motor has been specially developed for Race drones, such as the Mach R5 Racing drone. Thanks to advanced construction in the manufactory, its smooth, reliable and powerful performance is improved yet again. By introducing new center-slotted N52H curved arc magnets, the motor's response time is drastically shortened. As a result of the high quality materials used and the durable joint of bell and shaft, we were able to reduce the magnet air gap and stator lamination to a minimum. The smaller the air gap is, the lower that reluctance and the higher the magnetic flux (which is the magnetic analog of current), causing more efficiency and higher power!
