on track , is it having good control compare with sensored bl sys?

not sure what you mean by control, but once you get all your setting figured out, because there are alot of em, its just as good if not better than anything else out there. the 4700 maxx is more than enough for touring cars !!

I'm using a 4600 in my X-Ray, somewhat de-tuned (EPA turned down to 66% so I can play with the stock guys) and it's a dream. Occasionally I have a cogging issue after a good crash, when the ESC needs to read the motor's position again. The solution to that is don't crash :p

Plenty of runtime, too. A 6-minute race only uses about 1900 mAH from a pack when it's set up this way.

7700 mamba max in a Pro 4.....Insane fast till I realized the rear diff was too loose, proceeded to snug it up. next speed run was even faster....till.... a rouge rock wedged between the left rear wheel and the arm......40+ mph sliding donut....stripped spur gear....day over way too soon...still lots of fun
