I must have been wrong about the VeeTail Omni mixer, I tried again and it took my order. It's a programmable system that appears to have a lot of options (www.veetail.com). With a replacement and the Omni, that will give me the 3 mixers to experiment with. With my 8UAF, I should be able to come up with something! I've watched that DVD dozens of times and go through segments frame by frame to try and understand how the surfaces work. I'm PDS(pretty da.. sure) the LE flaps do not reflex upward, though interesting in the above pic. If you guys could could chip in $10,000 + travel to Russia, I'd go ride in one and clear this up once and for all! If only my wife would win the Powerball.............
