Here's a shot of the central steel box frame with the front members and the lower prop pylon stanchions clamped in place. The upper pylon stanchions will sit upon the lowers and will hinge forward 90d for travel.
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 (rough) shape of things to come
Had a heck of a good weekend working on the cart chassis. During the last week or so we had worked on tapering the front chassis members and working on methods to increase torsional rigidity.
