Made my own fan mount for the Arrma Limitless.
Seen several guys on YouTube who do not use heat sinks and simply just have the fans laying over the motor which seems to be popular.
Its designed to fit the stock brace on the Limitless and can be repositioned some what easily yet still maintain a good hold.
"Depending on your setup" there is a "lip" on this mount so it can rest upon the motor and also acts like a shield to help control airflow.
Once I test this (still waiting on Motor/ESC) I may add additional flow control to the design.
Comes with mounts to attach to the brace.
3 files include:
Dual30x30FanMount.stl
FanMount-1.stl
FanMount-2.stl
Here are the fans I used, BTW they blow "plenty" of air and can be used with a 2S Lipo which is my game plan. They are well made and have an aluminum case:

EDIT 4-2-21
After mounting my motor I decided to make a small edit on the mount itself. With the current version the fan nuts were touching the motor on my setup (yours may vary) so I placed 3 small ears on the mount so as the mount would rest upon the motor instead of the nuts. File Name 30x30Mount-V3
