It has been months since I have visited this fine site and now I have a question. I hope this is the correct place to begin?

I bought a new OS .55AX engine and have followed the break-in procedures to the letter!

What my queston is now that I have run a gallon of 15% fuel with castor/synthetic fuel through the engine is when can I expect to get max power from this engine?

I am flying a Tower Hobbies .40 Kaos ARF with a 11/7 prop now that I have used the first gallon of fuel. I broke it in with the 12/8 that was one of the reccomended props for break-in.

I don't want to lean the engine out too soon so I am still running it on the rich side.

Any help or other tales of break-in of the fine engine would be most appreciated.
