Kudos to you for taking the time to learn what you could from the sim and RCU. But if your plane hasn't been flown, then it is not set up yet. The simulator is a nice tool to practice what your instructor is teaching you, but the downside is that every model on it is perfectly set up and trimmed. Your plane will not fly the same way on its first flight. I've been in the hobby 4 years and I do maiden my own planes, but I always get a second set of eyes on it beforehand in case I missed something. I've only had a problem caught one time that way, but it probably did save my airplane. Resist the urge to get antsy now and go out hoping that everything will go ok. Of course, it might, but there are so many variables that the odds are against you. Even something as simple as the elevator trim being off can cost a beginner a crash.
