Just put a new ceramic front bearing in my nova/rex p5x this evening. Took a quick pic with my phone. Its a little out of focus. The crank has rbmods signature on it and an R engraved on the con rod. Looks like quit a bit of grinding was done to the crank and sleeve. I hope the rain stops so I can burn some nitro thru it tomorrow. I also hope the bearing takes care of the suspected air leak.
