This is my first foil I got this at the the same time as I got the board Slingshot Allen air. I have had a lot of front foot pressure from the start.Did a lot of modes to get this to work for me. Moved foil all the way back then drilled out two of the countersink hole to move it further back. Got the slingshot hook foot strap had that facing for-would. Had advices from axis had the wedge on the back wing .Got it working fine happy with the board .
Turns out board and foil don't rely work together needed track to be further back.
Just gone and changed the back wing to a 340 this has made a good improvement .
Heads up if your looking at getting a axis foil look into getting a smaller back wing 340 or 370 with the foil. Very happy with the axis foil looking into sub foiling and only need to change front wing.
