James May is out to prove why traditional, old-fashioned toys are still relevant by pushing them to the limit in spectacular, supersize challenges. From full-size Lego houses to bridges made completely ofMeccano, he shows what they are capable of.

In this programme, James takes model aeroplanes to a new level when he tries to make a full-size Spitfire out of Airfix. The venture soon hits problems when it becomes clear the giant 36-foot pieces may not be strong enough, and nobody knows how they will fit together.

James hopes he can enthuse a group of reluctant teenagers to help him pull it off - but he soon realises he has another big battle on his hands convincing them it is a hobby to be proud of.
