Here's the first layer of the first side of the first blade. While there will be no more 'shaping' on this blade, there will be a fair bit of trimming and sanding between layers.
In 2009 we set out to conclusively answer the following question... Can a vehicle be built which can go directly downwind, faster than the wind (DDWFTTW), powered only by the wind, steady state? On 3 July 2010 we established a world record by going directly downwind at 2.8 times the true wind speed with the Blackbird. Now we have begun to modify the Blackbird with the intention of going directly UP-wind faster than the wind - steady state.

The first of many
We've now started the rather long and rather laborious process of adding layer after layer of glass to each side of the propeller blades. We're going one layer at 0degrees and then one at 30d and one at 60d.
