RS props....two week turnaround....snerkle...
I had my Fett together in about 8 months after starting.....but as Lou said I had cash in hand and was lucky in aquiring various parts. I could have had it together in 5...but pushed back the time to save some costs.
The largest time sinks will be jet pack order, gauntlets, and helmet order / paintup. If you are painting it yourself you might be fine...but if you are going for 501st approval be prepared for some changes.
The largest problem with time frames on the costume is how much is involved with it. It doesn't initially look like much, but it's arguably the hardest 501st costume to get correct. There are so many parts and so much detail it's mind blowing.
