Noo noo - Interesting observation, will have to look for it next time out. Does it happen at all de-power trim levels, or more at one end of the trim range ?
What do you think of the kite with this bridle ?
If the E line is going slack, then the steering line must be distorting LE and wingtip into a deeper ‘C’, closer to the outer end of the V2 line, eliminating tension in E. So the LE of that wingtip around the old pulley point is only under support from the bladders and airflow pressures. Tension from trailing edge should tilt the wingtip bladder and put that wingtip in a higher AOA ( Angle of Attack ), which ought to move the wingtip LE out and away from the end of V2, keeping E tight.
Pump your wingtip struts rock hard too ? Makes me think the steering line attachment point is loading the LE too much and not enough on the trailing edge. Wonder what would happen if that steering line was attached to the TE ? Maybe an improvement in turning?
Hmm…. When I think about the wingtip folding together that I described a few posts earlier on my 7m, along with the tips deflecting together into a deeper C, there was also a twisting of the wingtips’ LE inward. Maybe it’s related to what Noo noo has noticed.
Need some close-up video footage of this weirdness, or better, many hours of riding !
BTW, a week or so back I had a great day on my 9m in GUSTY 10-30 knts, pumped rock hard and kite flew great, no weirdness. Also got to ride a friend’s ‘08 8m Rise, first time on an 8 Rise for me, as my only Rise is a 12. Wow, fun kite.
