I like the comparisons Splatter! I had really never heard about "bearing maintenance" before now. I always thought there was enough oil content in the fuel to take care of these little guys. Especially with O.S.; it almost seems to be a common theme with these engines. Rc-bearings.com lists a "most popular" bearings on their site and guess what engine takes the top 2 spots? OS 50SX-H for both.

Here are some more shots of the damage that was done: conrod nicked, rusted bearings, etc. The glow plug appears to just be missing the filament.

Anyone got an os 50sx or sx-h that they want to give up for parts.............?
