Both generators were on the same 35' tower, in a pretty good wind location. The 2x18 had some early issues, that's the reason it was down so many days. The 403 was very durable, I never did have any problems with it at all. But the point to this is, you can make a generator at home that produces over 4 times the power, for about 60% the cost of the small commercial unit. For much of the 2x18's life, it ran on a half burned out stator. Had the stator been replaced, the unit would have averaged much more than it did.
Now the problem is getting the home built units reliable enough. That's my next job, the pages to come will document that quest.
