Quick status update:
The doors are on, the latches installed, the hinges hinging.
The main gear have had their notches made and are test fit. The front fork is ready for the wheel and tire. The landing gear and strut fittings have finally been bolted into place.
I did have some problems with the Matco wheels. Despite following the drawing, I can not separate the front wheel halves. There does not seem to be a retainer clip or anything like it.
