Using your T - Motor PACER P1604 Motor is easy. First, make sure to choose the right KV option according to your drone's requirements. If you're using a 6S battery, go for the 2850KV option; for a 4S battery, the 3800KV is the way to go. When installing, align the 9x9 mounting holes with your drone frame and use appropriate screws. Connect the leads carefully to avoid any loose connections. As for maintenance, keep the motor clean. After each flight, check for any dirt or debris and gently wipe it off. Also, regularly inspect the shaft for any signs of wear. If you notice any strange noises or performance issues during use, stop using the motor immediately and check for possible problems. This will help ensure your motor lasts a long time and keeps your drone flying smoothly.
