Norm yes thats what I had in mind the two stage effect.But it dont work worth a durn-nab-it.So I just went back to my usual 4 blade limppy-along deal.But it was just greed on my part,I thought after spending $76,000 on parts and supplys it should charge a couple of batts guess not.Need more work.It is approching tornado season here,one of them bugers will show the alt whos the boss.Just hope it dont blow my shack down too. I read all about the stalling blades and the dissapearing amps.My mind went and got so weak I nearly passed out. MelTx
