Wind generator

[akflyer 1427]

So the ole Rotax stator quit charging on me so I did a quick Internet search for a wind generator. .. seems the only commercial one is 9 pounds and 750 bones. Another search showed a guy that made one from an 12 volt starter for rc engines. Since I only have a half dozen or so of them laying around I made one as well. Today I played with props on it and settled on a 9x5 prop on it Wichita gives me 14.6 volts at cruise. I just had it hooked up to a volt meter so if the weather is good tomorrow I will hook it to the battery and see how many amps it will charge at. At any rate, looks like I can charge the battery now for less than 30 bucks in parts.

if your running an lead acid battery you should be good. I wouldn't dare do it with a lithium without a good regulator ha they burn fast

No lithium. Odessey 625 in the ole gal. I'm going to run it through the Rotax regulator so I shouldn't over charge it.

nothing wrong with saving 720 bucks building your own. Should give you a little extra beer money

_{Hey Lenny - what kind of parasite drag penalty did your mod incur?  Anything noticeable?}

No drag that I noticed. It's in a pretty dirty area so I doubt there is much. Still playing with props to get the output right. I cut a 14x5 down to 8.5x5 but didn't have time to try the new prop for the generator.
