G2 esc and different motor

i bought a g2 brushless system second hand and told the motor was playing up so i got a good cheap deal.Do i have to buy the same motor again for this ESC or could i fit maybe the fusion exceed Motor or similar or am i better off buying a fusion exceed combo deal.
cheers

The G2 system is sensorless and will not work on the fusion . . .
In my honest opinion go for the Fusion system its far bettter than the G2 system

Yes but the Fusion system is good as i used it however you must change the settings using the Card u can buy to linear or somethign making it give that extra punch if you dont your very extremly sluggish of the line but i agree with gazza its well worth the buy , myself i had issues with the G2 brushless again with the motor , i used a proper set up one tho and wow there good

Ive raced brushed for a couple of years and now decided to go brushless .
Gazza what brushless systen do u have also what lipo,s do i need to get
cheers
