The clothing is made of all metal gears, which means that the main shaft and gears are both made of iron. 2. 360 Degree Servo rotates continuously. If need to control the angle, plesae choose the option 180 Degree Servo 3. For 180 degree servo, some controllers can not control the angle accurately; please use a professional PWM Servo Controller to control the angle, as shown in the video: https://youtu.be/zv6vd7eud_o - Light Weight - Less Noise - Connector Wire Length 250mm Products Description: For: Mini Car / Mini Ship / Helicopter & Airplane Model: MG90S SG90 upgraded version Weight: 12G Speed: 4.8V&0.10sec/60 degrees; 6.0V&0.09sec/60 degree Torque: 4.8V&1.6KG-cm; 6.0V&1.8kg-cm Voltage: 4.8V6.0V Connector Wire Length 250mm Dimension: 22.6mm x 12.1mm x 22.5mm Dead Band Width: 5 usec Interface Specifications: JR / FP General Accessories: Multi-arm, fixing screws Scope: Helicopters KT, fluttering, gliding, small robots, and other models Recommend Model: Mini Car / Mini Ship / Helicopter & Airplane Shipping list: MG90S Gear Mini Micro Servo(The amount depends on your choice.)
