OK, I was well on the road of getting a Traxxas Revo, but my dad had his reasons and wouldn't let me spend $450+ on my first truck. So I am either getting a XTM Racing Nitro X-Cellerator or a HPI Racing MT2. I am leaning towards the MT2 because it is 4WD, but I am wondering how fast will this thing go stock? I know that the X-Cellerator goes about 50mph, stock. What about the HPI MT2 (not the 18ss, just the original)? Will it do 45? Or what would it take to get it to 45-50? What engine would really bring this beast out?
