For HK, I think the brushed version is better choice, much smoother, decent speed .. (~ 50km/hr with nimh/4s lipo, and over 60km/hr with 5s lipo, but watch temperature) The brushless version is fun and crazy .. but since it is a Traxxas, so it is Fragile .... arms, drive shaft, skid plates, roll bars, wheels, tires, wheelie, centre diff etc etc upgrades in order to make it up to normal 1/8 standard ..
And for $1,800 HKD less, if you really like the car, and plan on going Brushless, you can buy your own ESC/Motor ..
