If you can not find a fan for your esc there is few easy steps how to find the correct fan

1. Measure outer diameters of your fan and select the right size fan.

2. Check the voltage of your broken fan. If there are no markings on it you can measure it from the esc connector. Remember that the voltage is different if you run the ESC on 2s, 3s or maybe 4s depending on ESC.

3. Select correct connecting plug from the remaining fans. Hobbywing uses three different connectors:

- Basic JR type servo connector. It has 3 pins and normally only two of them is connected. Note!! always check the polarity from old fan or if there are marking on the side of the esc.

- JST type with 2 pins. This is compatible with JR type. Note!! always check the polarity from old fan or if there are marking on the side of the esc.

- Small two pin ZH-2Y connector this is one of its own and in V3.1 series it is connected in its own fan port.
