Low rates as others have already said, but I'd add that a forward CG will also make it easier to fly and land. That is move the CG to the front of the listed range, it'll be more stable and less twitchy. You can always move it back later on if you want, or when your ability to handle the model improves.

If you can get an accomplished flyer to maybe help you out with checking the setup (setup becomes much more important as the size/speed of the model increases) and the maiden flight, or buddy box with you, that'll pretty much assure you of a successful transistion.
