ok, thanks guys. I pump my kites by the 'ping test'
No gauge:) ~60kg only. Got the bridle measurements from the FS site, will check them.
I'm not concerned about flutter when turning, that's expected.
It flutters in normal flight at the window edge. That's annoying. It just does not like 25-30kn coz up to 25 it's ok. And I would think a 9m kite would handle 25-30kn with a 'breeze'. It is more like I'm fighting a kite with all that flutter and jelly fishing. Very annoying, and if Boost 9m v2 is the same, well, that's not great.
I can't imagine an Edge v8 9m behaving like this in 25-30kn, it would be a disaster.
I don't think it is loosing air tho, but good point, will double check as well and report back.
