The harder the edges are pumped up the better they work. I'll leave it up to you to decide how much is too much.

I usually go until my oldish pump can hardly do any more pressure.

This is indeed a great kite for old bones. Very soft landings are easily achieved, even if you go huge.

Yup, needs more air. The closer you are willing to take them to bursting the better they fly.

Pump hard and bar pressure on heavy will do the trick.

I found I had the problem with a 19 and 17 and it was always related to lack of pressure. Whenever I attempted to boost, I would collapse the wing tips.

I also add a litle spit round the O-Ring to improve the seal. And make sure clamp your struts.

i pump all my edges from 7 to 19 to 9 psi and always run med settings on those that have 3 settings and heavy setting on the 19 . 100kegs

no wingtip folding

Excelent ideas!!
Kiteboy: Will do this in future.
Bigtone: Will clamp from now on...and spit on the ring!
Everyone else: thanks a heap. under inflated and bar possilbly too light. Will try the tip bend for test before launching MAX V
Archie: Vaild point mate. I felt I had this experience and came to mostly the same conclusion, (operator). Or a combination of all the above at least. My last post was a question regarding stalling behavior on Edges, because of this likelyhood. Plus it wasnt really the right kite for the pretty dismall conditions I was testing in. largish ocean swell, up and down all day, but was still super fun, chop hoppin for hours.
I still managed one of the best mornings on the kites in a long time, issues aside.
A few observations that I really loved about this kite when it all came good: (no expert)
The race bar, which initially thought I would hate. The trim was very precise and very easy. A bar is something I thought I would never feel passionate enough to comment on but it was a very nice change.
Sheeting was quite tame compared to past sessions on the rebel.(13m). Kinda contradicts earlier comments but just felt smoother reactions.
One handed bar control. Tacking all the way out through this ocean swell to about.....398 meters...... and turning and chasing the swell back in using one hand on the bar all the way was a first for me, and a huge rush...Again, this was on the light bar pressure so probably part of my issues.

Very excited to get them out in some clean wind and some flat water.

Hell. I just pump my edges till the center strut doesn't have any wrinkles then I go for the ping test. When it goes from thud to ping your ready to go.

The only time i have had issues is when there has been sand in the valve and the kite has gone down. Then it gets all flappy.

So... clean out underneath the seal.

No mate got nothing to do with tightening it more than other systems liKe this. Just make sure there is not a speck of sand on that seal (Both sides). Had similar issues, checking for sand sorted that.

You'll fold any kite if you get it wrong, especially in slack line moments, the bigger bloke you are the more the possibility, the older 7 struts were rock solid as you'd imagine, the newer models are a bit more prone, pretty sure this was a bit of a grumble from puetzy, but he's a big bloke, after the mini bridle was put on the 2013 zephyrs back lines pigtail ( which improved turning and tip folding when aggressively turned) I was surprised it wasn't introduced on the bigger edges , on this subject back line tension is something worth checking, shorter back lines will increase the chances of tip folding as it's flying on it's back lines as much as it's front,
