Speed ±10%rpm (tested after running for 1 minute) 2. The motor supports up to 12V voltage. It is recommended to use 7.2-7.4V battery 3. Motor shaft diameter: 3.17MM This motor is fully waterproof and can be soaked in water for a long time. But after playing in the water, you need to pay attention to three maintenance points: 1. Be sure to maintain the motor bearings with lubricating oil immediately. 2. Be sure to dry the water between copper the and the carbon brush as soon as possible and do not wait for it to dry naturally. 3. The plugs on the ESC and motor should also be dried as soon as possible. The larger the T number, the greater the torque and the slower the speed. The smaller the T number, the smaller the torque and the faster the speed. -Package Included: 1x set
