Putting oil on the cam before the first run is not required. I just personally do it. Just like any model engine on the market. When assembled at the factory they get some oil inside, but my question to you is how old is your engine, or how long has it been since it was built?

You can't answer that question and neither can I. So common sense says that if a engine is new, and the parts are metal to metal, would it not be prudent even if not stated in the instructions to oil those parts?

Did you hurt it probably not. Could you hurt it, possibly.

Its not critical, and I don't write the manuals, I'm not an employee of YS. I'm a modeler just like you. I just happen to have flown YS engines for many years and have experience with them. I'm demanding of my equipment and do my best to keep it at the top in performance. In the competition world you can't afford to have problems with your equipment. The oil in the cam gear area is just that, a ritual I use to eliminate problems with damaging cam gears. Before I started the ritual, I might have had 2-3 cam gear failures in the previous 3 years. Since I have started the ritual I have not had a cam gear failure. Its been almost 5 years since I have had any cam gear trouble at all, and 5 yrs of oil before the first run.
