How do I know what fan I need for upgrade? Looking to upgrade fans for esc and motor.

The stock ESC fan is 25mm and the motor fan is 30mm. Any that you find that size suited for RC cars should fit.

Ok. Thank you. I'll look into it

I've never had to upgrade the ESC fan, but for the motor fan, I highly recommend an aluminum case. I trashed the Arrma plastic fan in 2 runs. Aluminum case fans are much more durable. There are many 30mm aluminum motor fan options on Amazon. Don't bother with the more expensive branded ones. They're the same exact thing as the cheaper ones. All of the fans with this design are durable and work well. Just manage the wire, if it gets worn down and exposed from moving around and rubbing stuff it can cause ESC glitches.
