Both the Windseeker 502 and 503 work ok. The 502 is a two blade but now has 3 hornet blades on the small hub. The 503 has been the most reliable mill and has the original 3 blade. When one turns Hornet PMA's (I have the 6 volt and the 12 volt versions) there is significant drag from magnetic attraction and working around the shaft one doesn't have to worry about losing any hardware as the neo magnets are very strong. The Windseekers are PMA's also but one has to look inside to tell if there are any magnets there. I use these mills in 20-50 mph winds as solar is more reliable but when the wind does blow and this can happen nicely for 24 hours at a time the 5 windmills I have really produce! Cutin speed is not important for me. But higher voltages I think are. The 6 volt Hornet supposedly does 60 amps at 12 volts at 35 mph just when the noise starts (maybe 50 volts). This is probably near 1500-2000 rpm. In the winds I use all the blades on everything are turning. Incidently, the Hornet 6V exceeds the output of the Windseeker 503 at about 25 mph. No problems yet with too much heat burning wires. Thanks for the comments and suggestions. I don't understand these mills and the electrical theory as well as I'd like so am looking forward to further discussion.

OK, glue plus strap!
