What kind of radio do you have?
Yes you use both airleons and rudder to turn the plane, althrough if your teaching yourself, it is much harder to do a good equil turn using both so your turns will be wide and ugly. A rudder is more or less really important for a twin more than a single so some people rarely touch the rudder but its good practice to use it anyway. I dont suggest using your plane in your "neighborhood" find a deserted parking lot or a large LARGE FLAT field if you are going to teach yourself. Although i really dont recommend you do teach yourself. If you use a trainer you will learn faster with less chance of screwing up. Balance checks are all over the place. Just type your question in a search engine, or on here and im pretty sure you will find your answer.
One last comment on the engine break in period. I think these days with the newer engines especially the so called "break in period" is highly over rated. Just run the normal fuel through engine and use a slightly smaller suggested prop for the first flights and thats all you really need to do. Oh and if your going to crash, dont go nose first.[&:]
