So I got myself another X-Wing fighter and finally put it together. I can now field 'Red 2' and 'Red 5' twin section (see below):
This is (yet) another Revell purchase from their "pocket money" series, but rather than pay full price (which seemed an awful lot of pocket money) I waited for a Hobbycraft sale last year. I'll be doing the same in January 2015 for other items, including perhaps another X-Wing, in the series.
Note: I never have seen a normal TIE fighter yet (although I do possess a model of Darth Vader's advanced fighter). The intention is to get three X-Wings (I need 'Red 3') and Darth's plus two TIE's for the 'Trench Battle' scene [shades of "633 Squadron"] as shown in the original Star Wars. May have to pay some attention to candidate rules soon!
