Notes:

The winding is our own modified winding. Can be activated using the RC ESC.
***Cannot work without ESC***

***Jetfan has a very high rotational speed and high power, please do not test without protective measures****

***After exceeding 120000rpm, the heat will increase rapidly. Please do not work at the maximum speed for a long time. You can reduce the voltage to prevent it from reaching the maximum speed, or you can use the knob to slow it down a bit***

****If you have made a 3D printed shell, please note if the hardness is sufficient****

Tips:

1.Due to the fact that the product is modified, it may appear defective in appearance.
2.Made of aluminum alloy shell, it has a relatively heavy weight and although it has a large thrust, it is not suitable for use in aircraft models, can be used for DIY fans and other purposes
