As others mentioned, great work going on here! It really puts the boot to the heinie for slow turtle-folk like myself!
I'm still working on the tail group of the Seamaster. For a Mach 0.92 aircraft, it has very WW II-ish control surface hinge lines, with the fin and stabs having 90 degree edges. Mach-2 just provided deep, uneven recesed lines for these, plus added some globs of plastic in the recesses just to give us something else to fix! To correct this mess, vac-form techniques apply - cut control surfaces away, back the cut lines with sheet plastic, rebuild hinges, then sand everything down until it looks right.

It is tedious, but extremely easy and does not require a lot of measuring or precision. Easy-peasy Japaneesy! But day-um, the parts sure are wavy!
I also started looking at the cockpit. Laying out the positions of the seats and consoles reveal a marked difference in what Mach-2 provides.

The way the Mach-2 kit is, the pilots would be squinting through the small curved triangular side windows (of which Mach-2 thoughtfully molded an extra frame going through them), rather than through the large flat-paned windscreen. But make no nevermind, as a new canopy will be vac-formed. I also noticed the real seat in the Seamaster had their backs extended a bit, so the True Detail seats will be modified accordingly.
