Hey guys, I'm new here but have been racing R/C cars and trucks for many years. I just bought a XTM Mammoth. What a beast. I have the truck tuned real nice. I wanted to share how I clocked my XTM going 47MPH. If any of you own a GPS that can track speed, Strap that baby on your truck and let it roar!! I clocked it without my body, so I'm sure I can get to the recorded speed of 52MPH out of it.
