Thanks Montague ....exactly the answer I was looking for.
So does that mean you weren't going to accept anyone's answers until you got the one you wanted?
Just kidding. There ARE a number of issues to deal with but, I was at a Scalemasters Qualifier this past weekend (one of the static judges) and we had to put in a few flights in light rain in order to ensure an official competition.
If these guys, with their scaled out planes (some with 1000 hours into them), were willing to fly in light rain, I'd guess you can.
