Like the FLEDGE standard rotor, this is a high power and high speed black rotor, which uses neodymium magnets that boast the highest class of high heat resistance. Adopts LUXON AGILEs industrys first "M.F.C.S." which allows you to change the rotation and torque characteristics of the motor without compromising the balance of weight and moment. The motor characteristics of the lower the LV value, the more rotary and the larger the torque type. The standard rotor is LV38. Cannot be used with LUXON AGILE, LUXON BS, LUXON KG, and LUXON. The image is OP-15094 Speed Rotor (LV30), but the product sold is a high power rotor (LV45). Please be aware of this as an image.
