Frank, Gerry was right! You don't need to adjust the values by much. The starting values in the AA-5B were 0.000, 0,000, 0.000, which I have now changed to 0.175, 0.000,0.000 The only one I played with was the first, I found that less than 0.175 still had the tail down too far, and much more than that changed the performance dramatically. Its still slightly tail down, but now you can land on the tricycle. Next question - I also downloaded a freeware Europa, which seems to want to taxi at around 60 kts. Is there any way I can slow this down? Frank T.
