Thanks for all the nice comments.
A couple final editions - 1st is a trim tab with aluminium drinks can 'hinges'
- and 2nd is - well a few people have asked me about this. I always make up a cardboard box for a new outdoor model, particularly the scale ones. These are folded up from old boxes or sometimes several old boxes and stuck together with hot glue. I try to make them as small as I can to fit the disassembled model into. Everything then to do with flying that model can go in the box, this is perhaps more relevant with scale models with scale props, spare parts like rigging wires, CG gauges, flying surface gauges etc, I even started putting the plans and templates in there too so at least I know where they are.
I started doing it after realising the only model that survived in a flyable condition from my aeromodelling youth and subsequent 25 year hiatus was the one that I made a box for

It makes storing them a lot easier too and hanger rash is much less of a problem
...Actually the first shot looks like a shameless plug for the Oxford MFC... oh well in for a penny in for pound
