Wind effects are relative to the aircraft's flying speed, not its scale.

Lets say a 1/4 scale Piper Cub flies at close to the same speeds as the full scale aircraft... In that case, wind will have close to the same effects on both. (but ground turbulence will bother the model more)

But a 1/4 scale F-14 isn't going to get anywhere near Mach 2... The wind will have a much greater effect on the model than on the full scale. A trained Navy fighter pilot easilly fly a full scale F-14 in severe weather. (I've witnessed carrier landings of F-14's in 25 knot {gusting to 40 knots, not counting the speed of the ship} winds, heavy rain, sleet....) Try flying in a storm with the model and you get toothpicks. (or fiberglass scraps)
