Congrats on the build! I came to this site completely green, and a few members really helped my OVER-analysis and questions along the way. Flying similar, a custom built (f550,Nazav2) and couldn't be happier. Aside from ALWAYS wanting to upgrade, the best way to learn is to stay low and take baby steps. Learn your rig inside and out. Fly respectively and you'll be set. I've learned if you have to question the legality or safety of a flight. Don't do it. Happy flying and keep us updated on the progress!
