I was training last week at cocoa beach with a 2014 lf envy 12, got about 3 hrs in, when I got back home I tried my 2012 lf envy but results were very different, my main safety did not want to realese lease when I pulled it, it worked in pre test. Next I had a problem of the kite always trying to over fly me then fall out of the air never had a problem on my lessons, wind was about 15 mph, maybe kite is set up wrong, I bought it used with no manual so don't know what to set things at.
