Hay Swavek
I think you need to leave only the front straps on in the furthest forward hole
Be powered up, in 12 knots 13mtr for me
The best conditions are 10 knots big slow kite 12/13m.
Point the board off on a beam or broard reach.
And be really heavy on your front foot no weight on the back foot
Back foot over foil mounting bolts.
Keep the foil board on the water until you want to fly.
To fly you need to be traveling 6kph and lighten the wieght on the front foot or a little press with the back foot. Like doing an ollie on a skate board.
Once flying try control the hight with the front foot not the back foot.
hope this helps.
