despite main bladder problems at the beginning - I love it!!!
maybe the reason was a little bit too short front bladder that didnÃ‚Â´t fill up fully the black cover at the tips - just my suspicion. I have an early production model (serial no. 14) so hope this problem is not actual anymore.
I had several attempts of repairing holes in both tips of the front tube. New holes in the tips appeared again with the first peak of pressure. Then I elongated the original bladder on both tips with approx. 20cm of an old naish bladder. No more visible holes appeared then, but still a noticeable loss of pressure after one hour on the water. Then I filled some teaspoons of talcum powder INTO the bladder - now it is fixed!!!
I didnÃ‚Â´t want to wait some weeks for warranty procedure so I had to solve the problem this way...
Impressions after 20+ sessions on the water:
+++ scary lift when powered up
+ good grunt at low end. Going upwind and jumping starts when the first white caps appear on the water
++ range comparable to Gaastra GXR 19.5 but you have to edge a bit more aggressively. possible to switch directly to the AMP 8.7 in higher winds.
++ turning and speed comparable to F1 Mach1 15.1 but much more stable
+++ upwind machine
++ great stability also in gusty conditions
- wing tips collapsed 2 times when I was fully loaded for jumping and pulled the bar in. back on the beach I noticed very little pressure in the front tube. After fixing the bladder problems I never mentioned this problem again.
--- veeery thin bladder material
summary: a great kite but some question marks concerning the bladders
