2 Brushless questions.
 

I just bought a Novak XBR Brushless esc and I want to know if I have to use only novak bl motors or can I use other sensored brands shuch as a Neo-one or an Orion Vortex

Second Question. I have been looking at the neo one motors and I have seen 2 different comparisons.
1)NEO-One 1 Star Brushless Motor, 13 turns.
NEO-One 2 Star Brushless Motor, 11 turns.
NEO-One 3 Star Brushless Motor, 9 turns
NEO-One 4 Star Brushless Motor, 7 turns.

2)Neo-One 1 Star 8.5T
Neo-One 2 Star 7.5T
Neo-One 3 Star 6.5T
Neo-One 4 Star 5.5T

My XBR is an 8.5 turn limit for brushless and no turn limit for brushed. Is it possible to use 1,2,or 3 star motors ar just the 1 star motor. Thanks

You can use up to a 8.5t BL motor on that speedo. Anything lower then that it was not designed for. You would then be looking at getting a Sphere or a GTB.
