A brand new airplane (forget about the brand new pilot for a minute or two) has a couple of hurdles to jump its first time out.

The engine has to run dependably.
The rigging has to be properly set.
The trim has to be worked out.

OK now, let's look at you as the person responsible for getting that brand new model through it's adjustment period alive.

Have you ever started an engine? If you haven't, then you've probably not learned how to adjust them to run dependably, much less learned how to break them in without ruining either yourself or them.

Now, since you've admitted to not having flown a model, how are you going to acquire the skill to trim an out of trim model? Sims don't even give you this practice in this.

Every week or so guys comes along here wanting to explain why they won't need the help of an experienced flyer. And not a one of them has understood that the process involves way more than getting the hang of pushing the sticks around. They have no idea what has to be done before they can actually learn how to twiddle the sticks. It's absolute proof how little they understand about the problem. And should be an excellent lesson why they aren't going to be up to the mark teaching themselves.

You've already not noticed enough to kill the airplane 3 times over before you've even begun.
Find a club and go watch them fly. Talk to some of them and find out if there are any flight instructors.

It may sound harsh to say it, but it's true. You don't know where to start, and don't understand the problems.
