The other night I pulled the engine to replace the clutch shoe that I broke myself, not due to a crash. My GPH was bought used and in excellent shape.

What I did find, though, is that the clutch shoe bearing was in need of replacing and that the fan had some cracks, so new parts were ordered. When I switched to CMT blades from the stock woodies, I found 1 of 4 blade grip bearings shot and needed replaced.

I am learning very quickly that even though a used heli could seem to be in great shape, there are just too many "wear" parts that could be in need of replacing. The parts that I have replaced are normal wear parts, minus my own breakage. Sometimes there is no way to tell until you pull a section apart to look.
