Hi everyone, me again. So I've been working on my independent study, and found myself doing so many repetitive calculations that I decided to make a spreadsheet that will do all of the heavy lifting. I'm offering it up here for a peer review and, if there are no major mistakes, for you guys to take and use as you want! That means private, commercial, public - I don't care, just let me know that you used it so that I know I helped - it'll make me feel all warm and fuzzy inside 
This spreadsheet will take you through designing a two place aircraft of up to three surfaces. I'm working on a three surfaces project atm, so it's currently got all the numbers for that, but it can do other things - for traditional configuration, the tail calculation is done at the very end.
CG calcs are at the bottom of the sheet. Feel free to say thanks or "you're an idiot, Jordan" in this thread
Also, if anyone wants to help me code, I'd totally love to put this into a more usable GUI (which I can design) - PM or post here for details.
EDIT: Just re-uploading to add some directions on how to use the sheet + a minor usability tweak.
A potential error that I'd like people to check is where I summed the lifting force of the wing - I summed the lifting force of each side individually then multiplied it by two, instead of using the total area. Could you guys just make sure I entered that equation properly?
Also, I've got a really good method for sketching aircraft configurations quickly, if there's interest in it after this I'll make a youtube video or something. It lets you jot down an idea for an aircraft in rough scale in under ten minutes with no math.
EDIT: Here are the permanent links to the latest versions of the drawing method and the spreadsheet application. Please read through the thread for development history.

NOTE: THIS IS A WORK IN PROGRESS. THERE MAY BE ERRORS IN THE CALCULATIONS, PLEASE DOUBLE CHECK YOUR RESULTS (and please report back if you find an error! :3)
