I wouldn't ask "how many people think I will crash" You're setting your self up for failure if you do. If you think your skills are up to flying you'll probably fly it well but if you have doubts than maybe you should try the trainer out and see how you do with that first. As an instructor at our field I see lots of guys that come there and don't do well partly because they don't think they can't fly good enough. Negative thoughts are a killer. I don't want to throw out old cliches but that's a big part of it.
