Lots of progress today. He's built most of the bottom third, including four of the legs on the bottom. The thing now stands up off the table. Also, at least one drivers' wheel has been installed.
It's only 3:45 here, and he's on about page 74.
He has made a goal for himself today, which is helping to keep him focused. He has decided that he wants to put the blue panel of rear afterburners on today. That means another 20 pages, but it looks like he could make that.
If he gets there, the schedule looks like 3 weeks from start to finish.
Sunday Update: After writing the above, I realized that pages 72-75 contained a single set of instructions that needed to be repeated 6 times, for a total of 7 "legs" for the falcon. He made all but two of them before jumping in the pool shortly before bedtime. So, he's not quite past page 75 yet.
