To start with - I too love old aeroplanes and in my youth, now alas a few years away and getting further away fast, I made many many models - my favourite WW1 plane being the SE5A. Also something of a favourite with the pilots, I believe, being fast, well armed and very tough by the standards of the day.

Now to diverge from the subject. If any of the contributors to this thread ever visit Brussels, don't miss the Air Museum at the Cinquantenaire Park - it is stuffed with interesting old craft, including a Fokker Triplane, Sopwith Camel, Halberstadt, etc.... and lots of more modern stuff, too (WWII and several postwar jets). And in the UK, don't miss the museum at Old Warden, particularly if there's a flying day.
