Feature:1. Practical Function: High purity copper winding maximizes efficiency. With high strength magnet, low friction, low noise and external carbon brush2. Reliable Performance: Brushed motor can achieve maximum energy conversion. Accurate balance and smoothness of rotor improve reliability and maximum speed3. Large Torsion: 540 brush motor has large torsion, strong anti interference ability, two way bearing, strong magnetic force, low calorific value and high power4. Overheating Protection: When the temperature reaches 100°C, the output power will decrease and the speed will slow down. When the temperature drops, the speed will return to normal5. 65A ESC: 65A waterproof brush electric control is compatible with brush motor, for Tamiya white plug, high power, and can be used for different types of ships or automobilesSpecification:Item Type: 540 Brushed Motor with 65A ESCMaterial: Iron, Copper, PlasticColour: Black Green540 Brushed Motor:Voltage: 7.2 to 7.4VMaximum Voltage: 12VLength: Approx. 53mm/2.1in (without shaft)Diameter: Approx. 36mm/1.4inShaft length: Approx. 10.5 mm/0.4inShaft diameter: Approx. 3.175mm/0.1in65A Brushed ESC:Battery Support: 5-9Ni MH, 4-6Ni Cd (4.8V to 7.2V)Li Ion 2 to 3S: 7.4V to 11.1VCurrent Parameters: Forward 320A, Reverse 160A, Brake 270ABEC Output: 5V/2A (power supply for receiver, servo)Functions: Forward and Brake, Forward and Brake and ReverseProduct Size: Approx. 43 x 30 x 28mm / 1.7 x 1.2 x 1.1in(without cable)Suitable Models: For Axial Scx10 90046, for Traxxas Trx4, for HSP, for Redcat, for Tamiya, for HPI installationColor: Black and Green.Package List:1 x 540 Brushed Motor1 x 65A ESC1 x User ManualNote:1. 1 to 3mm/0.04 to 0.12in error is allowed due to manual measurement2.
