"The Spin 99 ESC will not work with the 600-09 motor because it is a 14 pole motor. Do not use this ESC. You will need to use a Jeti Mezon ESC with this motor."
Please may I ask why not, re the spin 99? If it's the number of poles, I'd just add that the 99 is quite happy with the 20-pole Pletty Advance 30-10, and as far as I know, with the 28-pole Hackers.
