What size of outrunner have you been looking at and what type of materiel do you plan to cnc?
I have several different groups of materials which all probably need there own spindle. The rpm depend on the feed and speed rates greatly but as a rough guide.
Styrene foam, 4000RPM
Birch plywood, 12,000-15,000rpm
Aluminium 2000rpm or 12,000rpm

I’ve been looking at this spec below as an example, top speed as far as I can see from the fella who posted this was 1500rpm

270kv
100A Brushless Motor Speed Controller RC BEC ESC
CCPM Servo ESC Checker Tester
12v 350w, or old 500w computer power supply
