Do you think add a negative angle on the stab could have the same effect as having a larger on?
I have not tried that but I think in theory that is an option. The gong stabs are fixed angle. Maybe some others have tried that approach.
Tried Field Weakening and gained 6km/hr. At these settings was using about 3500W going 36km/hr but ESC/motor does not sound healthy.
Tried the Fliteboard prop instead of FR and got a significant improvement in power consumption along with a tiny bit more speed and lower vibration. Now at 30 kmh, the efoil consumes 1500-1600w, at 25 kmh - 1100-1200w.
Also, I increased the FW to 40A and got 40kmh top speed at 4kw. I am getting 10 kmh extra with this feature on.
There also was the winning noise above 30 kmh, so I ended up sanding the trailing edge to razor sharp and the noise was gone.
