Winds that affect models are usually a significant percentage..(. over 50 to over 100 %) of the normal flying speed.
Full-scales seldom have to encounter winds of this relative magnitude, unless they're trying to land in a hurricane.
Example.... you can't taxi a model in a 20 knot crosswind, but you can taxi a C-172 in such.
It's all relative, since the air can't be scaled, the model is at a distinct disadvantage when a wind is blowing.
That's when taking off and landing across the runway works. Or a "harrier" style hover-up and down..
Takes practice.
When it's too windy at the field on the flat, go to the slope! You will become a better pilot!
This is my CR Renegade 60" sloper in 45 mph winds... And it penetrates!
