Well ever since I got into the electric helis about a year and a half ago I have wanted to generate power from the wind to charge a battery to run my battery charger for the heli. Did you follow that?

So finally this weekend I got to test a wind generator I made and as I write this it is charging a 12v battery that I will use to charge my Rex 600 batteries. It is recycled wind as I see it. I use the wind to charge the batteries then use the batteries to make wind!

The wind generator is a small stepper motor that produces ac voltage. I put it through a rectifier bridge to get dc power. From there the power goes into a charge regulator which monitors the charge of the 12v battery. The stepper motor on Ebay is about $35 and the charge regulator was about $25. The rectifier was made from RadioShak parts and a wiring schematic was found on the internet. The most time consuming part was making the housing, blades, and tail. Plus I made a temporary but fairly sturdy post on the side of the house. Once fine tuning is done I will make a stand to put it on the roof of the house.

I made a sticker for my Heli that says "Flight for Free". I cant wait to fly the first pack off the Wind charged battery. It may seem like a lot of work for such a little payoff but it keeps me busy during the winter.

Now, THAT is cool.

When you get it all completed, I'll bet that you could sell a few....

Hell... I can fix that.
Uh oh..

That's great! How bout posting yer plans and some pics so more people might try it.

One of my best friends has lived off the grid (no hookup to power at all) via solar panels and a big bank of deep cycle batteries for years. And he is an avid RC Addict he has 15-20 planes and at least 8 helis. All electric and all charged from the sun. We call him GREEN RC

thats kool, now you need to put one on a electric heli to charge the battery during flight... and fly forever

We are already working on that with the static from the T Rex 500

i did something like that about 5 years ago in high school.

i had a spair rotor head from my nexus 30, and a set of blades. used a tail drive pinion for the motor that ran off the main gear, all mounted on a home made tri-pod. ended up with a 110% for the project. it worked great too. but after the project and my grade i broke it down so i could use the parts.

Man, BRILLIANT idea. Well done. A mini windfarm right on your roof. Please post pics, plans, links etc. as I am sure they would be popular!!

the nice part about using the rotor head is that you can adjust the pitch for the greatest efficiency.

I'll get some photos tomorrow after work.

The adjustable pitch would be nice. The stepper motor is good for 1000 rpm's and the blades I made are pretty steep so I don't think over revving will be an issue.

Later,
Mike

you would be surprised. are you into auto's? it isn't hard to get the blades to hit 2000rpm, and you dont have to be doing warp 12 to do it.

all purpose built wind turbines have over rev devices. on the show "How its made", they showed these hand made wind turbines for small applications (about 400 watts). there were these weights on it spring loaded and linked to the blades. if it spun too fast, the weights would swing out and change the pitch of the blades to slow them down.

if your going to have this thing mounted on the roof, you will have higher wind speeds, plus the updraft from a slopped roof.

just something to consider anyways. i use solar panels at the moment for my 12 volt charging
