My CRT conversion!

[Serum]

Very clean!

I would be worried about the placement of the controller though, isn't there a way you can place it somewhere else? not against the motor?

Also; with the warrior/micro controllers, you need to put some foam pads on the back of it, there are delicate SMD components on the back of that print, that are known to get loose if mounted directly onto something hard.

The maxamps 4000 packs in 5S on the 9XL might drop under the 3V per cell under load.

It's one cool conversion, congrats, you can have lots of fun with it!
