Are you talking about the Super Stock Plus Brushless system or the Super Sport Racing Brushless System?
Looking at the Novak website the Brushless limit for the Super Stock Plus ESC is 225 watts.

The 7.5R Novak motor is rated at 275 watts. So, on those figures it seems the motor wouldnt work.
Dont quote me on this though. Just been looking through the Novak website.
