Why is it collapsing? 5-line kite..

[hondamts]

Hi, I am new here but I have a quick question. I know today was not the ideal day to go flying but I was tempted to go and try my new 5 line kite (RRD Type Wave 2, 12M). I am uploading a video to youtube of me just trying to get it up and I was able to self launch using the fifth line (I know the wind was not blowing the right direction but..really wanted to try it). In mid air it collapses. Any reason why..I am scared to over inflate both leading edge/struts cause of past experience of blowout in midair hence the hesistation.

It's the like the kite would drop out of the sky (most likley due to wind) or sometimes just the wind tips would just collapse as if not enough air. I have a line that runs across from the left to right tip so that in waves the lines don't cut the kite and I wonder if I am pulling the fifth line too hard to power up but causing it to collapse.

Attaching videos soon.

Thanks
