The Hobbywing Xerun V10 G4 Competition Stock Brushless Motor has been greatly optimized to provide maximum torque and increased power. With a lower internal resistance, this motor is more efficient and runs cooler when compared to the G3R motors. To further increase performance the motor adopts a fully exposed stator core allowing more airflow over the stator. The motor also features a high-precision endbell plate to improve consistency and structural stability. Dual sensor ports can be found allowing for different wiring setups. Features: Optimized for more power and torque Lower internal resistance allows for increased efficiency and cooler running temperatures Fully exposed stator core for increased cooling effect High-precision endbell plate to improve consistency Specifications: Scale: 1/10th Turn: 13.5T kV Rating: 3950kV Cell Count: 2-3S No-Load Current: 4.5A Outer Diameter: 35.8mm Length: 51.4mm Shaft Diameter: 3.175mm Weight: 149g Front Bearing: 9x4x4mm Rear Bearing: 8x3x4mm Adjustable Timing: 30-60° Applications: 1/10th Stock Class Racing
