Is there a way of designing to get a TSR of 6, or do you just assume that unloaded it will accelerate forever, and match the load to peak at whatever RPM equals a tsr of 6, and then dynamically brake it past that.

I was also thinking that the tail could be designed assymetrical, so it would de-tune the angle of attack at higher wind speeds. Thinking on the run here; what about using one tail fin per blade, mounted above the piviot axis of each blade. Nah, the rotational force would defeat it.

OK, I just updated my spreadsheet with a tsr of 6, and got these numbers.

Height(m)    3                       
Diameter(m)    3                       
TSR guesstimate    6                       
N guesstimate    0.3
