I can't give you a full description of what I would say,,,,,,,,but, hopefully, this will be just one in a good long list of posts
so, somewhere in your talk, tell them about the feeling you get when you assemble the parts and it starts to look like the vision you had in your head when you started the model
that happens at different times for different aircraft, and for different people,,,,,,,,but, for me, to contrast two aircraft,,,,,,,,a Phantom starts to really look like one when I attach the canted up wingtips,,,,,,,,,and a Beech Staggerwing stands out from all other biplanes when I attach the upper wing "too far back" for being normal
I am probably not expressing this correctly,,,,,,,but, you know the time in the build that I mean,,,,,,,there is one for every model,,,,,,,tank, car, ship, aircraft, figure, etc
