Lotus kites have had some problems with breaking inner straps.
Get out of here! Really?
So did my S4 DLX 8m2. Cell structure broke clean along the ripstop fabric and so did all the inner straps like you say.
FS insisted I must have crashed it hard once in the past to cause it to brake slow, if I don't remember any crashes lately.
I stil find it unlikely, but have nothing else, but to agree, however the question is how hard of a crash was enough for this to happen.
And I got the quote for rapair and shipping without tax
3 Infinity2 bars pealing after a year, low quality velcros degradating and need over stitching!? They say it is an easy and cheap fix.
It will take a long time tor me to try something new from FS. I feel skunked enough already.
p.s.: Did I mention how weird does the S4 dlx wing fly, bad low wind, disastrous wind range, no steering at high wind.
