Oh in my first lucid dream I didn't manage to fly around - but in my second one I did. It's much cooler than I imagined! The wind, the height, the feeling... frankly it's quite hard to describe, but it definitely feels extremly real and absolutely magnificent!
If you have problems with recalling dreams then how about a mantra like "I remember my dreams." or "I wake up after every dream.". Be creative and think of something that means something to you and hence reminds you of its content. You could also try to set an alarm during nighttime in order to wake up during a dream to increase the chances of recalling it. The more dreams you put down in your dream journal and the more consistent it becomes the better your recall will be!

Good luck and feel free to ask if you would like to know anything else, I'll try my best to help.
