Novak sport pro? What is that? (old school?) I run a Novak GTS in my buggy, it works great in mod, 19, and stock. The only downside is the fact there are no adjustments on the ESC, so you can't dial in the braking which I think really sucks. Besides that though it is a very good quality ESC at a reasonable price. You can get cheaper ESC's that will take more motor, but I definately trust the quality of a Novak controller over pretty much any other brand. If you need more features you can't go wrong with the GTX, I've got that in the T4 and it rocks.
