Feature: 1. Superior Performance: 4 pole rotor design, powerful torsion and stable output power, low friction, low noise, high accuracy. High hardness aluminum CNC shell, high temperature resistant copper coil 0.2mm thickness silicon steel sheet, high permeability, high silicon content, good insulation and heat resistance. 2. High Durability, Detachable Design: RC brushless motor adopts explosion proof rotor, high toughness stainless steel transmission shaft and high accuracy superior bearings to make the motor super durable. Detachable structure design, easy to clean and repair, effectively extend the motor life and improve efficiency. 3. Safe and Reliable: The highly reliable electronic switch of RC brushless motor avoids the failure of traditional mechanical switch due to dirt and water. Proportional brake with 9 levels of braking power or maximum braking power and 9 levels of traction braking power. 4. Sparkproof Circuit: Brushless motor esc has built in sparkproof circuit, which not only effectively guards the battery and ESC connector from damage, but also guards the user from bodily injury caused by the strong electric sparks generated at the moment of battery and ESC connection. 5. Extensive Compatibility and Waterproof design: Eelectronic speed controller set is compatible with sensorless brushless motors and sensing brushless motors (only in sensorless mode), and is waterproof in all weather. 6. Parameters: RC brushless motor kit with super internal switching mode BEC, switchable voltage 6V 7.4V, control or peak current 6A 25A, can easily drive large torsion suit and high voltage servo. Advanced programming via portable LED program card.
