Do not grasp ducted fan by hand for testing, it must be fixed on the test rack. 2. It is suggested to remove the motor flow guide cover to help heat dissipation and prolong the service life of the motor. 2. Compatibility problems may occur in different ESC and jP ducted fan matching. Please pay attention to whether the ducted fan runs smoothly when using it. 3. Set the electrical parameters to try again, if the ESC can not solve the problem, only to change another ESC. 3. It is recommended to purchase JP brand or other brand ESC. 4. ESC setting: setting the entry Angle below 15 degrees (low entry Angle). 5. During use, the ducted fan needs to be checked frequently. 6. After using for a long time. Due to inhalation of sand and gravel and blade damage, the dynamic balance may fail. If you feel the vibration of the ducted fan, it is suggested to send it back to the factory for maintenance. If the vibration is too large, the blade will break and cannot be repaired. The broken blade can only be replaced with new blades. CNC machining aluminum alloy material, durable and light in weight.
