1:72 aircraft photo-etch shows that even the most widespread scale need not settle for bare plastic. Small cockpit sets with belts and a pre-coloured instrument panel make the best first fret, while more experienced builders go for Spitfire flaps or complete airframe sets for the Ju 52.
The smaller the scale, the more the order of work matters, and cockpit etch belongs at the very start of the build. Kits are in 1:72 aircraft model kits, the other sizes in aircraft photo-etch sets, and fine parts need good tweezers from modelling tools. A small cockpit set is an evening's work, and anyone who comes near the shelf will see it through an open canopy.
