Pretty neat looking!!! Good luck on your maiden flight. You mentioned she might be a little tail heavy. This plane is very forgiving. You can balance all the way back to 6" and it will still fly like a puppy. No bad tendencies at all. So if you are in the range of 4-6" I wouldn't give it a second thought. Mine balanced at 5 9/16" I love it there. Doesn't fly bad at all and is very easy to land.
Thanks,
