Go to ozone kites Chrono kite foil page and watch videos they have all you need to know about a foil kite - I taught myself from these videos - pretty simple you just need to talk your time for the 1st few sessions then easy as.

I've been flying both the 8m and 22.5m PL Charger 2's for over a year now and am happy to give you some advice if required? Have a look at my (small) profile posts and you'll see a vid of my 22.5 in action.
