I just got back into flying with a couple of buddies from HobbyTown. Been busy helping my son race rc cars for the last six years! I have two four stroke engines, '80s models, .60 and .90, that I would like to resurrect. I will probably need to install new bearings in both engines. What are my best sources for bearings? Thanks,

Just replaced the bearings in my OS 120 surpass. Check Tower Hobbies for stock bearings and Boca Bearings for high perfomance stuff. Good Luck.

Depending upon the exact models of engines you have, stock O.S. bearings should be available. Even if other parts for your engines are no longer available, many of the bearings are common sizes to the ones used in current engines. O.S. usually doesn't change part numbers when they have common parts.
