If you're determined take on your first flight alone. You might at least move all your trim switches around randomly before you take off on you simulater to get you ready for the real thing. Maybe it's just me, but I've never taken a new plane up yet where I didn't have to fly and trim on the move for a few moments to get straight and level. Experiance will get you through that, no experiance will get you a full trash bag. Not meaning to beat you up over your idea, but those that use an instructor tend to keep flying and become instructors later. Those that don't tend to be selling their equipment online due to frustration. It's a lot more fun to fly than to rebuild a wreck even if it's minor. Good luck.
