All I can say is at least a 600 is bigger, so seeing it won't be as hard as a 450 or something, lol!
I think the pics look pretty good for a first attempt. As my wife says ... when you are taking pics, you usually have to take a bunch before you get a couple which you like. Don't be afraid of taking some pics when it's up there ... actually, is it automatic? Or do you have a channel on your Tx which allows you to take the snap?
