Unless he doesn't want to make it obvious that he did it.

Hope I don't stir anything up with this post. But all of the above that thing 8 mph with gusts to 15 would be grounded here. I live in southwest Oklahoma, and the song line that says "where the winds come sweeping down the plains" is exactly correct. 8-15 mph is a normal flying day around here. We don't start thinking about not flying until it gets up to 20-25 (or straight across the runway). In fact, a windless day around here makes us all look like beginners. When you get used to landing with a headwind to slow you down, on a windless day we all spend a lot of time coming in hot and overshooting the runway. I know that it can be scary for a new pilot, but I train students all the time with the wind blowing. The point I'm trying to make is that flying in the wind is just like any other aspect of this hobby, it's all a matter of practicing until you are comfortable. For Nilo I would recommend working with your instructor at first to fly in the wind, and then just keep practicing. Before long you'll be able to fly in just about any wind.

As a side note, if the wind is high (25-35 mph) but straight down the runway we like to do what we call "wind flys". We do a lot of hovering in the wind, not 3D hovering but pointing into the wind and slowing down your engine until the plane has no forward airspeed but is still maintaining lift. I like doing that right over the runway and then slowing come down to the runway for a "vertical landing".

I really have a blast flying my Avistar in winds up to 25mph. But when the transmitter antenna is being bent by the wind, maybe it is too windy.
