Bought a SLE last week from kiteconnection. Watched video's several times. Spent hours untangling lines on 3 different occasions. Frustrated. Returned kite for refund.
So sad to hear you experienced tangles and threw in the towel!
I've found that IF I do exactly as John Barresi instructed in his video/s, I have no problems at all.
I too am a relatively new flier. It just takes some patience. By winding and unwinding the lines correctly, all goes well.
The best
(est) method is having someone, with a little experience, actually show you how, not only winding/unwinding but getting you launched and such. I find seeing it in person really sinks in... if I can do it anyone can!
If you decide to try it again (which you should and I hope you do) find someone to get you started. There are so many flyers eager to help!
It's such an awesome experience, I'd hate to think a few tangles has ruined your
(future) joy of flying.
