Hey addikt,
I had 2 dos's last year and still have my 12. Now I'm used to them it's a rare occurance but yes they certainly like to Hindenburg if your not onto them.
The dos has a very heavy leading edge and also can build speed quickly, when you stack ir mess up the kite can easily shoot right up your window and get to the point where it's way past you and it just takes a little tug on the front lines and it's falling.
Hey it a performance kite at the end of the day. I have learnt to feel the kite doing this and generally pull on the bar to send it into a loop if I can to try and stop it falling. This is not always possible of coarse.
Another cause of the dreaded Hindenburg is over sending it while jumping. If you fall vert and get dunked.... the lines go slack when you resurface and there she goes again.
I can fly my 12 in about 12 knots with my Nobile skim but it certainly keeps you on your toes. While up and riding there's no prob as the kites happy while moving and builds apparent lime no other kite I've ridden, but the walk downwind back to the beach across the sandflats in light winds can be a real challenge. I learnt to loop it and run with it, yes plenty of entertainment for the peanut gallery that's awaiting wind
You'll learn to minimise this eventually by better flying technique.
I got myself a 2010 helix to replace my 10 and love it, but nothing I've demo'd feels like a Dos.
If you want a No-fuss kite that will hardly ever do anything wrong get a Switchy. But they come at a perfomance cost. The Ozones float back well too but I personally don't like the way they fly
hope this helps.....
,you bet, was it the word Hindenburg that gave it away, ;)
