i bought a used flux hp awhile ago. I've been and still am accumulating parts for it. When all is said and I will have gone through whole truck. New ceramic bearings, lube, diffs and all that. This is my first RC and I understand it should be cleaned after each use. But how many reccomended runs can I have on it before I should go through to clean and lube bearings, diffs, center drive and all that? I will be running it on street mostly with some grass and a little dirt.
