Hi Mark,
Absolutely brilliant!
Brought back memories of building model planes out of balsa wood, tissue paper and dope when I was a young lad in the UK. The worst incident was when one of them landed in Leigh Creek one Christmas Eve, and I had to wade in to retrieve it. The water was bloody cold, being UK Christmas Eve, and my mum was NOT impressed! But at least my plane was able to fly another day (albeit with surfaces a bit warped...)
Cheers
Neil
