Welcome, Bobby, and GREAT to hear that you pulled the trigger on ordering your RS armor! While you "hurry up and wait" for BBB to arrive, I would suggest a few things:
1. Get all your build supplies lined up and on hand. Nothing worse that having to stop in the middle to order or buy something. Link here.
2. Once your kit arrives, start a build thread. Trust me on this one. Does it take extra time? Yep, but there you can ask all the questions you like (no matter how small), and add photos. Lots of them. Adding pics is especially important when you have an issue.
3. Hopefully you will be aiming for Expert Infantry and then Centurion levels after Basic 501st approval, and this is MUCH easier to do during your build rather than after, and not as difficult as you may think!
I have a thread here which will answer a lot of questions as well as show you what we look for when approving those.
4. Most importantly.. take....... your....... time. I 'm sure you want to get it done so you can get out and troop, but rushing leads to mistakes. Consider it a marathon, not a sprint, and you will have one awesome looking set of armor when you are done.
We are here to help every step of the way, all you you have to do is ask.
