I raced the 1/12 last night, had a great time. I hadd a few problems though. My rear axle bearings, one of them seized, and two got crunchy. I replaced them with some cheap bulk bearings from the shop, but eventually I wantto get some decent ones. Any thoughts on where to go for good, cheap bearings?

I also broke a rear wheel. How should I prevent this? I know the obvious answer is "dont hit stuff".I was thinking of something more along the lines of nerf wings. Any thoughts on this?

And the same with the front, I havent broken a wheel yet (knock on wood), but should I be making a front bumper? I have plently of old TC3 bumpers, made from Kydex, should I cut up one of those?

Thanks
