I have built it 'wheels down' and with the additional fuel tanks as that's how I finished the 'original'. I think back then that it was a case of using all of the parts. Ah, these happy pre-spares box days.
The blue I used turned out rather darker than expected but I decided to stick with it. The final colour and marking scheme will be rather less than accurate but what the hell - if it looks OK it'll do for me.
Next time (with a fair following wind) the completed model.
