I have two inflation valves on my wing and able to have different pressures on the strut vs. LE.

During yesterday's light wind session I inflated the strut a bit harder (about 0.5-1 psi) than the LE. First time I ran different pressures on the wing.

I thought I felt that I could get going easier. Can anyone confirm that stiffer strut makes pump and going easier? Or maybe I just had a better flow

In general what are the tuning options for strut and LE and when to apply these?

Mattis Ghio says he always keep full pressure in the strut.
""> Do you change PSI on the airframe for more flex or less flex depending on conditions?

Yes, it's a major performance factor for me. I play with the pressure from my leading edge a lot, but never from my strut. It helps me to have the correct response from my wing for pumping in different conditions. For example, when the wind is light, I deflate my wing a little to have a longer pumping movement with a bigger amplitude, and this helps me to get quicker on the foil. I'm also deflating my wing when the wind is gusty and requires a little twist to avoid being catapulted. On the other hand, I increase the pressure when the wind is strong and consistent, to have a lot of stiffness for racing.""""


PS: He rides OceanRodeo Aluula wings (very stiff!) so maybe this will not work on other models.
