Xavier AVERSO - new website - new rotor blades

[Victor Duarte]

Hello gyro community,

I just want to tell you that i am the webmaster for Xavier AVERSO's website.

I just finished his new website :

http://www.averso.info

An english version will be available soon, sorry for the delay.

Something new : Xavier AVERSO sells a new rotor and new alu extruded rotorblades.. they are not any vortec products but are made by a specialist of extrusion he can trust.
As usual, each rotor, each blade is balanced and tested in flight before delivery.

I hope you don't find my announcement too "commercially aggressive".

Xavier Averso is probably one of the best gyro pilots in Europe , a man with a tremendous test-flight experience and an available and friendly person that doesn't hesitate to spread his knowledge kindly.
He is the person that fought for the ultraligh gyro here and we must thank him for being so free now.
He is my instructor and i am proud to be his friend.

Thank you

Victor

Very nice Victor, I particular like the history part, some of the pictures from the 70s are great.

Thank you, Vance

 

[Victor Duarte]

Vance,
I find you and Xavier have similarities in the sense we can admire all the achievements you did over the years..
cheers

Victor,

I am curious, why has he chosen extruded alu.?

Cost, Consistency?

Is the rotorhead different/unusual?

 

[Brent Drake]

Looks from the video. A very short take-0ff for a 2 seater.
I like the looks of the blades. Any idea of price?

Fergus :
I am not Xavier, so i can't reply fully for him, so, take it for what it's worth.
All i can say, according to him, is that the composite rotors are LOTS of work and some customers don't understand why they are more expensive and why the manufacturing delays are longer.
So, in order to match some requests, he just created the ALU product line that is simpler to manufacture, faster and finally cheaper.
The rotorhead for alu blades is simpler : no need for "swedish yokes".
Fergus, i suggest you contact him directly : [email protected]

Brent :
for any pricing, contact him directly : [email protected]

Thanks Victor, That all sounds about right.

I have flown the composite rotors and was very impressed.

Victor,
Nice looking web site. I enjoyed the history section showing the gyros he's built over the years. It's interesting that the gyro he was flying back in 1974 kind of resembles a gyrobee. Are all his prerotators shaft drive?

 

[Master Roda]

I do have to point out that the reason people choose composite (carbon Fiber) rotors is because of overall characteristics:

1. Tensle strength is better
2. They are lighter, overall, and per foot.
3. They are useable "on condition" (there is no set life span).
4. The torsional rigidity is better as well.

I don't feel that fiberglass exhibits these same qualities.

I won't get into why extruded rotors are bad.

The added expense in composite (carbon fiber) rotors is well worth it in my opinion.

BTW, Wind lends advantage to takeoffs as well as landings, notice how the two place floats to the ground? Not typical of calm air is it?

I really like the website.

Tim :
all the prerotators were not shaft drive, in the early models, it was "simply" a small rubber friction wheel that rotated the rotor wheel.
Not very efficient but far enough at this time.

Jon :
you are about all right excepted for the torsionnal rigidity : the alu blades show a surprising torsionnal stiffness, impossible to twist one just by hand.
I can't argue on what is better, alu or composite..they just are very different products.

For those of us for whom it is not "obvious" would you care to give dtails about what you consider bad with extruded rotors.

[Brad_King]

The main reason poeple don't choose Carbon blades. $$$$$$$

 

[Brent Drake]

I've e-mailed Aversco 2 times never had a reply

 

[Mike G]

Victor (zeeoo)
Does Averso speak English?

[Victor Duarte]

Hello Mike, Brent,
you got it... Xavier Averso's English is terrible (as he said)
It is one reason, the other is that he wants to build and sell rotors that he can try and adjust on a machine it is built for.
I also think that Brent's request was about a 30 footer or more and it is the limit he can build, as i said previously, the only machines equiped with large Averso rotors are "local" machines.

 

[Caribean_gyro]

but woody is flying a twinstar with some? I wonder if they are 30 foot.

[Brent Drake]

Aversco just got back with my emails. He said he does not speak english and had to get a translator. They do not make 30' blades. He said the extrusion process would be to hard and likely not a good blade.
Bonjour

- Désolé je ne parles pas Anglais, toutefois un traducteur informatique me permet de comprendre et de lire les messages de " rotary forum "
- réponse a votre question : je ne vends pas de rotor de 30 pieds car je ne vends que ce qu'il est possible d"essayer en vol et je ne dispose pas de gyro assez lourd
pour cela.
- mes rotors les plus grands sont de : 875 cm pour les composites et de 860 cm pour les metalliques.
- dans quelques semaines vous trouverez sur mon site des informations sur mes rotors metalliques extrudés.

Cordialement

Xavier AVERSO

Hello

-Sorry I do not speak English, however a computer translator allows me to understand(include) and to read the messages of " rotary forum "

-Answer has your question: I do not sell a rotor of 30 feet because I sell only what it is possible d " to try in flight(theft) and I have not of gyro rather heavy

For it.

-My biggest rotors are of: 875 cms for the dissimilar and of 860 cms for the extrudé.

-In some weeks you will find on my site of information about my rotors extrudés.

Warmly

Xavier AVERSO

Please tell me more about your rotor blades. I'm looking for a set of 30 ft blades for a twinstar

Thanks

Woody has 27" on his twinstarr-lite.

I'm sorry but I have to say, I build aluminum rotors and they are great. However a carbon fiber blade is much superior in all aspects. If you take a close look at the construction of other blades compared to a carbon blade, you will notice that a carbon blade is one piece. Which makes it stonger, just from a manufacturing standpoint. If we were to compare raw materials you will find carbon fiber has a superior tinsle strength.

I'm not going to throw a bunch of numbers at you to prove my point. I just wanted it to be understood that I believe carbon is better.

I have handeled both materials. I know what they are capable of. Yes they are "very different products".

Jon

EDIT: If you can twist any blade by hand your either a gorilla or its not flight worthy.
