When I got my 14m RISE, it flew awesome out of the bag, brand new. But after about 10-12 days of riding(especially after a couple of overpowered days) it began flying weird - lost the smooth flying, driving forward through the air feel, backing up and falling out of the air unhooked, even literally flying backwards. OR sent me the bridle specs - nothing stretched, EXCEPT the E2 braided spectra line that the pully runs on.
Ross thinks the stop knots tightened up, making the distance between the knots longer, thus the line length increased. Which is probably right, because the distance changed about 3/4” on one side and a full inch on the other. But WOW, that inch difference makes so much difference in terms of how the kite fies. It has made me aware of how important the tuning of the bridle is!!!
So if you think your kite is flying funny - check your E2 pully line length knot to knot. John Z said he would post these for us.
