RE: Questions from a first time builder
Read the build threads. I think that RCKen did a "pay it forward" build of an LT-40. It's not a SSE (I've built 2 SSE's so I do recognize the diff [:@]) but the steps are very similar. SIG does an excellent job on their instruction manuals. A thread by MinnFlyer is a decent read. MasterAlex, HookedOnRC and Iron Eagle all did very good SSE build threads.
You might open up a build thread for your kit just to get a community of fellow builders that are familiar with your plane and can chime in on any issue that you may have.
If you have a LHS (local hobby store) whose owner is a well recognized builder, buy your stuff thru him(her) and use it as an excuse to badger him with all of your questions. I've taken bits and pieces to nearly completed kits to my local guru for his invaluable input.
And HAVE FUN!
TTFN,
