Hey Radcom, You have purchased a quality engine that can last a long time. Why not just go by the book and break it in on the stand for a few tanks and then fly it rich for the rest of the gallon. If you did not get the manual you can find it on the OS/Tower web sight or right here on RCU with a little searching. Some flyers just start them and fly them and do fine but I just prefer to do the bench break in. You could probably read all night about the different advice on engine break in but I think you really need a little help from someone with a little experience. Once you learn to start and tune your first engine you will see that there is no magic involved but just a little common sense. Safety first around the spinning prop.
