S3 and M3 giving a shot! Checking how the default no-mods factory-made wind turbines go on the wind

We have some nice wind today to do the preproduction tests on the M3 specifically, and well, S3 shows something I was not expecting prior.
In short the conclusions are as follows:
1. S3 was able to peak 72 watts today, which is really great for it, given the shitty generator it has.
2. M3 was able to peak 300+ watts today (not sure if I was able to locate in on the video though).
3. M3 should have the tail reworked, it has to correspond to everything said here: www.windynation.com/blogs/art...
4. M3 should be given a decent height, as planned, twice as much as in this video.
5. M3 should be given a proper cable, almost twice as much as currently. currently it's copper 2.5mm2, and will be 4mm2 copper.

My solution to the tail always looking to small is, if to big the reaction time would be quicker, resulting in the blade onthe side of the wind could invert, resulting in lose of power , to small and yes spinning out of the wind and around, an average size tail would forgive thoughs small side gusts resulting in slower reaction time directing to the wind with on lose of power, i think this is what the wind turbine industry call furling, but furling in sailing term is for takeing a sail down due to much wind, ive also come across furling out of the wind from over spinnig and to protect the generator,, but think the generator can look after its self, the over spinning, brake not holding the blades still and i think its furling in, controling the direction into the wind, forgiving thoughs big gusts, like pulling down a sail on a sail ship, thanks Henry

even the default factory one will work nice even the turbine is given the stable laminar air flow - which is impossible in our standard home areas. however, in general here are the rules for the wind turbine tail: www.windynation.com/blogs/articles/sizing-your-wind-turbine-tail I plan to follow them while redoing the tail on my M3.

Great read, thank you, calculated i get about a month of perfect stable air flow, split up into hours days weeks at 40-50mph over the autum winter, then a gusty 20-45 with 40-80 2-3 times a year averagely. wished i had erected three turbines in a triangle or four in a square so when one would catchs the 45mph then the other ones would in theorie catch the 20mph resulting in a nice current charge. longer rod to the tail would slow the reaction down due to the distance it would have to travel to redirect the turbine.

Like you said you have to add longer tails to all of them. Cheap ones.

@ModernUkrainianHomestead 26 дней назад

no, S3 sits quite well on the air. no such fluctuation is seen, that tiny one is perfectly balanced at the moment. for the M3 - yes definitely, I had specifically mounted it that way as it is - to show you how it behaves, and then we will compare how will it go after the tail modifications.

at 15 min, is the noise we hear coming from the wind mills?

@ModernUkrainianHomestead 27 дней назад

yes, the door was open, so yes. the wind is crazy, very gusty. kids didn't want even to go outside. inside the house there is natural silence. as I always say - if the wind is over 7 m/s - you won't want to stay outside, so don't worry about the noise, you will not hear it inside.
