Some news. I decided to make my own plane.
Length - 50sm
Width: fuselage - 6sm, wings - 55–60 sm
Passengers: 104 (1st class - double seats - 16 pax ; Economy class - triple seats - 88 pax)
17 rows = 34 seats = 68 wooden details......o shi.....
I started to draw blueprint
Size to size with 30sm ruler
Also i decided to use some metal (for doors mechanism, gears, engines and maybe for wings)
