i purchased a rev kite blast nearly one year ago from windofchange.com.
Some weeks ago, the seams ripped at both sides between the black and transparent rag. I flew this kite last year and this year only a few hours. The wind was good, not too strong, below 5 bft and there werent any crashes. The bars are all well, only the seams and rag ripped off at both sides. Of course I assembled everything right, the blast was perfectly flying for some hourse and very good controlable. The damage occured during the flight in the air, I could even watch and hear the sail ripping .
I have no idea how this can happen.
Some weeks ago, I returend the kite (only the sail) by mail to windofchange (Kent Kingston) who send it to you. I was in a hope of a waarenty problem, because in my eyes it looks like a material problem maybe oft he seems or sail. Unfortunaly, Kent informed me that the only solution will be selleing me a new sail for over 130US$.
I am a bit unlucky with that solution, as i mentioned above, the sail damaged during flight. I have a lot of kites, also from rev, I had never a failure like this. I hope we can find any solution, because flying the blast was so much fun.
Please, also note that I flew a second rev blast in exact the same conditions, which did not show any damages at all ! (I bought two rev blast from windofchange)
