Sidewinder compatability
 

I just ordered the Castle Creations Sidewinder 4600kV combo, I heard it's a nice, fairly inexpensive system. But reading about it more, it seems like i may have problems with motor compatibility if in the future i decide to run in a spec class with a 17.5T motor limit.

Does anybody run in a spec class with this ESC, if so what motors are you running, and how does it perform?

Would i be better off returning it and buying the similarly priced system like the Novak Havoc Sport Sensored ESC?

Thanks
