I had a desire to build a De Havilland Beaver so I looked at my favourite site Outerzone and found a couple of plans I liked but none big enough. I wanted a span of 2.4 metres.
So, I decided to scale a 1.8 m to a 2.4metres or 130 percent. I printed the plan I liked on A4 paper and started from there.
