Even with the rudders all the way in I have a little to much weather helm. I do mainly long distance racing and all of my previous boats (P16, P19, H20) were trimmed to neutral helm.
My H20 was always sailed downwind with only one rudder down. Has anyone tried this with the Spin up? I need to experiment more.
I would not recommend sailing with only one rudder because sometimes you need the added rudder control. The rudders on my Taipan are small enough that I've spun out when using only one rudder.
When your rig is properly tuned, you will still have some lee helm downwind. The reason is that when you hoist the kite you add a tremendous amount of pull in front of the center of lateral resistance. There is just no way around it. But the amount of lee helm downwind and weather helm upwind should manifest as just a gentle but steady pull/push on the tiller--it should not require heavy pushing downwind and heavy pulling upwind. If if does, something is outta whack.
