Feature: 1. SUPERIOR PERFORMANCE: RC cservo is equipped with a high accuracy potentiometer and a high resolution digital chip, quick response time, high interference immunity, low noise and fast heat dissipation. 2. WATERPROOF DESIGN: The 20kg RC car digital servo has waterproof rubber sealing screws and is made of first class materials to ensure a long life. 3. FINE CRAFTS: RC servo with hard anodised high accuracy metal gears for greater accuracy and longer service life. The CNC machined aluminium centre housing enhances heat dissipation. 4. 0 TO 270 DEGREES ANGLES: RC servo can control angles from 0 to 270 degrees, with good linearity and high control accuracy. It can be rotated 360 degrees in case of power failure, which is ideal for robot joint activities. 5. WIDELY USED: 20kg RC car digital servo can be widely used in robots, robotic arms, climbing cars, remote control boats, remote control aircraft, manipulator, etc. Specification: Item Type: RC Servo Housing Material: Aluminium Alloy Servo Size: Approx. 40x20x40.5mm / 1.57x0.79x1.59in (Without Cable) Colour: Blue Operating Voltage: 6V-8.4V Operating Angle: 270 Degree ±3 Degree (500 to 2500usec) Pulse Width Range: 500 to 2500usec Neutral Position: 1500usec Direction of Rotation: Counter Clockwise (1000 to 2000usec) Deadband Width: 2usec Operating Current: 140mA - 200mA Torsion: 6V 17.2kg.cm 8.4V 20.3kg.cm Operating Speed: 6V 0.15 Sec 60 Degrees 8.4V 0.13 Sec 60 Degrees Applicable: For 1/10 1/12 Scale RC Cars, Robots, Ships, Manipulator, Etc. .
