The stator is 15.5 ins 12 coils 70 turns of #14awg single stran (and yes ghurd the trip to Barbados would be good lots of sea and sand,and bring along Flux Danb and the whole board) i had a small turbine up (10 in diam disc 16 1x1/4 round mags 12 coils #16awg 36 turns 41 in blades that gave me about 4 to 5 amps into the same batt pack 4 x 100 ah connected in parallel 36vdc and climbing open circuit. I made the bigger turbine same method hoping to get more amps with a slightly larger blade. i have a larger blade 5ft diag which i will try when i can get this one down. But does not a bigger blade turn more slower ? i have quite a bit of pictures but they all get mixed up with the ones that were posted already

Yes the bigger blade does turn slower and that will match the very low cut in speed better.

With a 10ft prop you will have more power to get the thing out of stall. Even so I think you will need to run at 24v especially with the single strand of #14 wire.

When you do break out of stall I think you will be surprised what you can get out of it. You seem to be in a good wind area. If you get those winds regularly I would not aim for the lowest possible cut in speed. If you start producing at 8 mph you will likely do better than aiming for a few mA in lower winds.

I hope he wants a face to face apology...

Given the output, etc, would anyone have a guess at a decent new stator for 12V?

Also the 12V amps such a stator could make with the same blades and rotors?

I had it figured at around 800W, however I am not good at this stuff, not even a little.
