Today at Tamiya track I hit the EVO running with Tamiya B2 Tires. I had to see how it will handle wth this tires since it is very probable to be the spec tire for the Nationals. On my first run I had a hard time entering the turn (pushing) but had plenty of tracation exiting it. After more adjustments and with the help of a goood friend, I was able to dial the car before the end of the day. Here is the bad part. I probably got to do at least 6 packs of run today and at the end of the day. the ball bearing that's holding the small bevel gear inside the front gear box broke, the steel shield leterally popped out and was floating on top of the shaft. Talk about cheap bearings, and why Tamiya had a full set of ball bearing upgrade for the car.
Anyway. The car is no longer smooth and I hope it's just the bearing and not another stripped bevel gear.
