RE: Building a large foam plane
G'day
If you live in the UK you probably know about Tony Nijhuis but if you don't, his website is worth a visit for plans etc. A friend of mine built one of his Lancasters but sadly he did not built it all that well and it is unlikely ever to fly unless some serious work is done on it. None the less, Tony's designs are great and I am sure you could adapt them to foam
I visited Duxford three years ago. As my wife and I pulled up in the car park, two Spitfires thundered down the strip and proceeded to chase each other round the sky for about 10 minutes before landing. The sound of the Merlins was AMAZING.
The rest of the collection was pretty amazing too. Concorde 102, Comet, Harrier, Vulcan, Mustang, P-40, Sea Fury, B-25, Dragon Rapide, Tiger Moth, Mosquito, Hurricane, Anson, Viscount, VC-10, etc etc etc
Not far from where I live in Australia is the Australian War Memorial in Canberra. There, as part of one of the displays, is G for George - a Lancaster. There is also a Mosquito, P40, Mustang, Me 109G (which still has its original paint job and looks totally war weary), Me 163, Me 262 and much more. George is quite easy to get close too and is a very impressive aircraft with his 30 foot bomb bay.
