I made a couple adjustments this morning with it, we were suppose to get some 20 mph winds today, in hopes it would spin better, I raised the tower a bit and realigned the motor and drive shaft, unfortunantely wind didn't happen so got no mesurements on output from direct drive, does seem to spin a little easier though. I am thinking I may have to go 3 to 1 ratio, but still not really sure about that, I am going to try making 3 blades, app. 4 foot long, wing shaped, 8" wide. The wind speed in this area isn't very good especially in the summer time, I am thinking I will need to grab as much wind as I can and I will need more power to allow for gearing up for the motor. Another question I have. to me it doesn't seem to make sense, but has anyone tried putting flaps, like on an airplane wing to help with blades stalling? You would get increased turbulance over the top of the blade, which would give more lift, but I would think the increase in the drag would make it not feasable?
