<mark style="color:blue;">**Q: If used in the drivetrain, what wheel size should I use?**</mark>

A: Any 4" wheel will work. Going any larger than 4" will run the risk of not having enough reduction.

<mark style="color:blue;">**Q: Can I use other motors besides the Kraken X60?**</mark>

A: Yes, any motor with a 2" bolt circle is compatible. This includes CIMs, Mini CIMs, and NEOs.
