I'm awaiting delivery of the CL-600.
Apparently it has an unusual way of doing the cabin windows, it has a clear drop in strip of polystyrene that fits into a trough on the OUTSIDE of the the fuselage, I believe the Yak 42D is done the same way but much bigger and includes masks!
P.S. Here's a pic of my Amodel Falcon-10, (top photo). The main wing is not yet fixed into position!
And the bottom photo is of my Amodel Falcon-. 50, with the "dreaded" Mach2 Jetstar behind!..
