This build has seen a couple of firsts on my part. It was the first time I had completely scratch built any aeroplane, wood, plastic or Depron. Saying that, I originally started to build a Hurricane MkI from moulded Depron and even got to the test flight stages with it, but I quickly learned that scale aerofoils really donít work to well at small scale. Too many crashes and not enough plaster moulds survived to make it worthwhile pursuing further so I decided on a fresh start and some new design ideas.

My second first was using an airbrush. On recommendation I put a Harder & Steenbeck Evolution at the top of my Santa list, and the big guy came up trumps. I knew if I wanted to end up with a model that came anywhere near resembling its full scale counterpart Iíd need to learn how to wield one. An airbrush would also allow a thin, controlled layer of paint to be applied so keeping weight down. In fact the acrylics I used have also created a toughened exterior layer on the Depron too.

Here are the details of the specification. I'll post up more details of the build when I get some more time:
