RE: How Much Wind For Training?
That's because you're expecting it, anticipating it, playing it from learned experience. We forget how it used to blows our minds when the model does things we didn't input. Don't you remember the first full symmetrical model you ever flew? Gosh, it isn't effected by wind much at all! But think back to the first few trainer landings when it was bouncing and bucking and your knees were knocking. That's wind. Thirty years ago I learned to fly R/C with two-channel gliders. We went looking for wind (updrafts) and boy, is a two-meter sensitive to the slightest changes. You find them because one wing lifts before the other.
I have flown in 25 mph winds with .40 size models. But there are gusty days when the mostly 10 mph West wind is interrupted with 20 mph Northerlies that I choose to leave my 15 pound 34cc gasser on the ground. Too much work near the ground. We have winter flies on snow and some years you have to hold the model down until you throttle up to keep it from skidding backwards or weathercocking sideways. Smeared a few in such conditions, but it's all part of the rote and ritual of a good chili fly.
