As a side note - isn't it funny how the carbon maffia has bamboozled everyone into thinking that if an aircraft is made of carbon fibre, it will automatically be lighter? Far from the truth - they're often heavier. Resin isn't light.
Even more astonishing is the hate aimed at wood - did you know that Birch wood is 1.7x times stronger than Aluminium in Modulus of Elasticity? People simply refuse to believe that. In canoeing for instance, a wooden cedar strip kayak will beat both a carbon fibre and an Aluminium one hands down in weight.
So Robin, Extra (the aerobatic ones) and the rest might have gotten it right: a wooden wing doesn't corrode, doesn't fatigue and it will almost always be lighter.
