LRP Vector X12 Octa-Wind BL motors
LRP have introduced the 2nd generation of their XTEC X12 technology, which feature an 8 time (Octa) winding instead of the previous 4 time winding, the effect is a different power characteristic resulting in much higher performance. The LRP R&D team has increased the number of copper wires used in the motor, resulting in lower resistance and thanks to the lower heat development of the octa wind less energy is lost resulting in higher efficiency. The end result is more power.
