Dave, do you find that you run out of rudder pedal at about a 15 kts crosswind with your coupe, so when you land in a 45 kt wind your still in a pretty good crab. I have a Alon with spring gear and rudders and run out of pedal at about 15 kts and find it harder to land in even a 25 kt wind with the spring gear. I have been going to Texas alot, what airport did you say you guys were based at? My wife and I fly formation and may stop by. We're planning to go to Terral, TX in 2001. Have you been to the Hondo cafe in Hondo? Great cafe. gene
