Brushless motor, Aluminum alloy motor can low resistance dual layer PCB w/nickel plating, easy soldering tab, oversized low friction ball bearing, hand wound coil winding, precision hall sensor w/adjustable timing, maximum air flow ventilation openings, fully dismountable for easy maintenance. The Speed Energy Race Spec series brushless motors are specially designed to meet today's professional RC racing demands. Every Race Spec motor features race proven technologies targeted to improve the most critical area in racing: Better Cooling, Lighter Weight Extra-large openings are strategically placed throughout the aluminum motor can to improve cooling. In particular, major parts of the rear section is hollowed out. This not only improved air circulation, but also keep weight closer to the center line of the car chassis for better handling. The angled rear air outlet further improve cooling by accelerating the hot air as it escape from inside the motor. A nice finishing touch is the "Frozen Black" hard anodized surface coating, which provides superior radiated heat cooling effect compared to other silver or glossy black finishes widely used by other manufacturers. Smoother Power Delivery, Higher Efficiency The sintered and nickel plated neodymium rotor is optimized for smooth power delivery and high efficiency. While a motor for bashing may emphasizes on producing massive low end torque that just create unnecessary wheel spin, Race Spec motors are designed to produce a broader and flatter torque curve, which allow more precise throttle input and easier control.
