10-4 on this, Matt. I'm pretty sure I can ship that wing core before I leave for Tucson.
As for having it done in time, well, at your age you should have both the energy and the time to get it done well in advance of the Nats and still not neglect your studies. I remember when I would stay up almost all weekend working on planes at your age. Heck, I still do that sometimes these days... Only it takes me more days to recover after one of those marathon sessions.
Billy Werwage used to come in a stay for a week or two at a time and we'd work literally until we dropped. Whenever we woke up (sometimes in the middle of the night) we'd go at it again until we dropped. We got lots accomplished in a short amount of time, and we kept each other going. Not sure I could maintain that particular schedule these days...
I find it useful to make a daily list of things to do and I try to make it realistic. I push myself to get everything on the list accomplished before going to bed. However, if I'm just fried, I'll reschedule tasks for the next day when I'm fresh instead of doing a bad job when I'm tired. You can make this sort of list of attainable daily goals for your new ship and you will be surprised how quickly it will go together.
I find that what often holds up modelers for days is indecision about how to accomplish a certain task on a new plane. They simply stop building and anguish over how to do something. That's where the value of these forums really comes to light; ask a question here and you will receive a lot of answers! Pick the ones that make the most sense to you and get busy building.
If you have a few "mentors" whom you really trust, call them and ask questions as you go. They won't mind; they did the same thing with their mentors years ago and it is a chance for them to "Pay it Forward!" Ask and ye shall receive...
Try to multitask. While one thing is drying, work on another. Organization is key to building quickly. Try to foresee what materials and supplies you will need for the next several days of work and get them into the shop so they are waiting and ready when you need them. Hobby shops are scarce these days and rarely open late at night in the midst of a frenzied building session.
