Traxxas Summit Extreme Crawl off between Rock Crushers and Stock Canyon AT tires

After the yard crawl off, I decided to get a bit more extreme, huge rocky terrain. Again I tried both sets of tires. The Rock Crushers continue to have the advantage with more ground clearance, but stock work way better with the stock servos (go figure). In this course the tires did better in different spots, but the stocks made it further in this case (might of been the driver, this was very challenging terrain, to walk and drive on)
