If the butterfly -- or clearnav, with future software -- did read out 3 d wind 20 times a second, this would be a big advantage. Not only could you detect lift long before F = MA gets the glider moving upward, you could tell upward gusts from forward gusts and sideways gusts. Dynamic soaring might even become possible, or at least better energy extraction from gusts. Even the 302 has the necessary sensors, my impression is that we're all waiting on the software development.
