Hi Warrior
I did a very quik wind test on the Lakota. Then I put it up on my store roof.
10 mph 5 amps, 15 mph 20 amps, 20 mph 30 amps, 25 mph 60 amps at 15 volts for 900 watts.
I didn't go any faster. I did this test in town at my store so testing was very limited. S-10 wind test truck VS city blocks?
I was very pleased with the results so I installed it on the store. That was last year and its been flying flawlessly ever since.
It dose seem to furl a littel early. I'm goiny to adjust that. I'm using the Lakota blades on a motor conversion here at home and at 28.8 mph it does 2025 watts. No furling on this one. These blades are very quiet.
Lakota clames some of there customers are seeing 1800 watts from the genny. I think thats quite posable.
About cooling. This unit has a very heavy and nice fined aluminum heat sink body.
There adds show a cutaway view of the insides. That one thing that atracted me to this unit. It looks like one of my motor conversions. 3 phase 8 poles. It has a slight bit of cogging but if you short the leads you almost need a pipe wrench to turn it.
I love it. Sure beets the crap out of a 403.
