From the feedback ratings of my preferred Ebay seller the Fly Hs 123 is 'flying' off the shelves. Given the antique nature of the Airfix kit the new Fly offering looks superb with its finely moulded resin, plastic and etch parts - at least in the box. The 'Eastern Front' boxing includes four options on the decal sheet (the Legion Condor and 'China' options feature in a separate boxing). A selection of resin parts including the one-piece cowl are bagged separately, along with two sets of fuselage halves, with and without head rest fairing. From the parts break down - undercarriage legs moulded separately - an 'unspatted' or partially 'spatted' build will also be possible..
