Increase bridle stiffness

[ocayon]

If you see that different wind speeds change the trim angle of the kite, have you tried increasing the stiffness only of the lines that would represent the bridle system?
That would constrain the kite structure in a more realistic way, I think.

I increased the bridle line diameter from 2.5mm to 3.75 mm, but the result is still the same: CL/CD of 5.0 at 6 m/s wind results in CL/CD of 5.25 for low wind speeds.

I think that the unrealistic polars are causing this effect.
