Using your RCINPOWER GTS V3 1002 motor is easy. First, make sure it's properly installed in your FPV racing drone according to the drone's manual. When choosing a KV option, pick 14000KV for more torque and slower speed, 19000KV for a balanced performance, or 22000KV for high - speed racing. As for maintenance, regularly check for any loose parts or signs of wear. Clean the motor gently with a soft brush to remove dust. When not in use, store it in a dry place. Always be careful when handling the motor to avoid any physical damage.
