Here's my build and info:

- Arrma Typhon 6S v4 (2019)
- Replaced ESC with HobbyWing Max6
- Replaced motor with 4985 SL-1650KV
- Replaced tx/rx with DX5C and SR215
- Replaced Servo
- Why did I replace everything? Water damage...
- Location: Hot, Texas
- Experience Level: Built 10+ quadcopters from scratch, but this is my first RC car

Question: I had a few shutdowns on the stock ESC and motor. I've just swapped those for the HobbyWings. How problematic is heat, and should I be installing fans on the motor or adding air scoops to feed the ESC?

Picture attached for grins. All the orange crap is 3D printed.

Thanks for your time

Stock esc fan should always be in service and I like motor fans because they can never hurt. I feel they work well too.
If you can pick up a cheap lazer temp thing from Harbor Freight or wherever, it may help give an idea of whats up.

How are those fans mounted into the motor? Did you screw into the heatsink fins? Awesome shots by the way.

It's a fan mount that a friend was prototyping and I was a lucky guy to get the opportunity to test it out. They aren't available right now but hopefully in time we'll see availability.
Thank you for the compliments. 😊

Here's the fans on the mount but not on the vehicle.

@oddworld The stock esc fan is pretty weak airflow wise and lots of folks report broken blades on them after a while from bashing. I see you have a lot of printed parts so if you want I have STLs I can share to adapt the stock 35mm fan mounting holes so you can add 30mm or 40mm high rpm/cfm fans on top of the esc without removing the plastic cover. Thingiverse has lots of 30 to 40mm adapter designs but not any 35mm sized ones so I had to design my own so if you want them just let me know.

35 to 30mm adapter example:
