I recently brought a 2011, Park, 10m. I used it for the first time yesterday and
I noticed the wing tips on the trailing edge were bending in slightly when I turned the kite.
The kite was properly inflated and I tried it on medium and low power.
one of the guys on the beach suggested that some kites can do this when they are worn out. As far as I can tell it's in pretty good condition, but i'm still a beginner so I don't know much about kites yet. Hopefully I didn't buy a worn out kite..

It was a pretty gusty day. About 20-27 knots. Could that have something to do with it? I weigh about 78 kg. Are there any other reasons why this could be happening?
Any solutions?
Thanks!
