I had both of my sons out this weekend for there first practice runs on the rc8be's they got for christmas. Box stock setup with the holeshot tires. Tekin 1900 systems. Car looked pretty decent. Only thing I noticed after trying it was the on corner exit push under power. So, we will make some changes to try and correct that. Nothing broke on either of the cars. Cars were both very stable and both boys did well with them. Only problems were the screws in the front aluminum hubs. The one car they kept backing out. So we ordered more screws and I plan on locktiting the crap out of them and then using some shoe goo to keep the screw tacked to the a-arm. Very little wear on the tires also. This is a 100% top soil sifted track so it's very tame on tires.
