Pitching problem

Hello
I have a problem pitching on my efoil, I’m too tilted backwards during navigation, I have a takuma wing (V100), at very low speed, the wing is very floating, my question is the next: should I reduce the surface stabilizer or install a shim to adjust the angle of the stabilizer?

Weird do have this problem with mine , you can try a shim
Is your mast perpendicular to the board ?

On my board I added a 4deg angle plate on top of the mast

This wing is a bit smaller then a gong M , for having tried a gong L , yes takuma v100 needs some more work at low speed

yes, I also put a corner under the plate, but it’s always the same thing. I think decrease the stabilizer to decrease the inverse of the lift
