I cannot believe how song and durable these arrma talion's are, I was out running it doing some speed runs, and my dumb *** has the thing going by full tilt and before I could stop it, it hits the stop sign and does a 1440 spin into the middle of the road with only one little issue, the top stud that goes into the front hub carrier popped out. I put it back together and good as new. That is bad ***, the thing was going at least 40-45, it is geared 20/50 and on 4s. I'm officially impressed.
