If you set the wind up maximum, along with the gusts value. It doesn't affect the Helicopters controls. Compared to the flex of the grass and the speed of the clouds you'd expect the aircraft to succumb to the force of the wind.
This is not really an issue and very very trivial. However it would be something that would be fantastic to have. Since flying / hovering in varying weather conditions does affect realism and is something taken into consideration when in combat.
