Mini Wind gen question

Max, I have not checked the amps from the wind turbine. I have checked voltage numerous times during various wind speeds and have found up to ~35 vdc. I am on the 3rd generation of blades, I have kept the length of the blades the same but have increased the length and amount of curvature of the blade. This gives more surface area for wind to act upon because I am not worried about rpm because it is like Don said, if it is turning, it is charging. I just wanted to see it start turning quicker with less wind speed. I have found that I cannot keep the blades/hub on the shaft of the gearmotor. I have filed a flat spot on the shaft to allow a better attachment but right not it is not in service. I will be glad to send you a picture of new blade vs. original blade if you like.
