It's real simple, guys... We added in a feature that was extra eye candy. The wipers are part of the plane, so we animated them...we didn't HAVE to add in the rain, but we did for some form of visual effect. We can only do so much within the limitations of XP, it's weather system, and the datarefs/hooks the simulator provides to us. Sooooo.... Don't like it? Don't use it! Just pretend like the feature isn't there (like on every other aircraft around), and you won't have to deal with it. Plain and simple. You can just use the regular X-Plane weather instead. My opinion is it's better than what we have now as default X-Plane stands, so I'm happy to use it and have it. It's things like this that ultimately tell Laminar where to improve. "Pushing the envelope" as they say... Also bear in mind it's design to work when the rain is "heavy" in X-Plane.
