Hey Acina. I don't have a real good answer for you, but I will let you know some of what I have learned since I joined RCU. Listen to what some of the "Veterans" give for Information. They are here to help. After reading tons of threads, I bought a SIG 4*60. (My first Kit) I have finished one wing, and I can tell you I am enjoying this to the limit. This is a kit that is recommended by alot of builders as a good first build. There are also a ton of threads on this build, which does help. Read, Read, Read and ask.
