For me I don't mind the wind, but it definately gets old. We get a lot of wind here, so you take what you can get. There's a reason our club is dead every single day (weekends included) after 11:30pm. It's literally me and my buddy out there every afternoon as people are scared of a 10mph wind and go home. For me too much wind is only when the plane doesn't have enough prop speed to move in a forward direction. And yes, I have flown in a 40+mph wind where my plane at full throttle was flying backwards! Landing backwards is just awesome!

For the faint of heart 10mph is about the limit. For the intermediate and those who want to compete in IMAC/pattern events better get used to fact that they're gonna have to fly perfectly in a 20-30mph wind, and CROSSWIND at that speed. Over that it's really just those that have a large visa or take out the beater planes from what I've seen.
