Doesnt come with the NX motor. You have to buy that IntialD car set.
I have found a good compromise with the yellow motor and green gears. Though really short runtimes.
The orange motor with red cant reach top speed (even if I let it go a distance). It does the best so far with the blue gears.
Oh yes, I also was hoping for more torque out of that green. It failed miserably to provide this, It does seem to give slightly more runtime, but the "need for speed" is so lacking in this.
Hmm before I jump on a expensive phast or a 4.2pro I think I will fet mine.
