RE: help first time build
Just in case no one has mentioned this, do yourself a favor and make duplicate parts out of heavy construction paper. I have never bought the same kit twice and some kits are worthy of building more than once. It also comes in handy when you have need of repairs.
Also, it is more time consuming, and no doubt you are anxious to get the build started, but the added time has the benefit of familiarizing you with all the parts of the build. Have fun.
