Hi Ian,
'Complicated' sums it up neatly. Everything is taking so much longer as I'm having to spend more time convincing myself that what I'm doing is going to work! Plus, I'm basically having to design so much of it myself as there are no drawings, and there's also the problem of making it 'buildable' -I've got to be able to paint and assemble this thing...
Rather you than me with the 1:43 917's, though - that's a challenge I won't be taking any time soon! The PA is an unusual choice - how about doing a stretched version with the prototype flat-16 engine?! Looking forward to seeing how the LH turns out, too.
Cheers!
SB
