Ukraine lines

[Lyle Spiegel]

new post on Amazon offering  flying lines
https://www.amazon.com/gp/product/B077XQ6985/ref=ox_sc_mini_detail?ie=UTF8&psc=1&smid=A3QOAKRTLJTQ27

it offers choice of  7 strand stainless or 4 strand brass (or brass coated?)
Is anyone familiar with the 4 strand?

$30? Kind of steep. Are they made from Unicorn hair? LOL

Not if you look at details. This information is from Amazon:

• price includes shipping
• Lines come already made in lengths.
• pre-made lines are pull tested.

No other seller does this. Also, this is the only distributor of 4-strand lines in US that I know of.

 Buy lines from Tom Morris $20.00 plus shipping.
  Custom Lengths and lines are wrapped not crimped.

Why would i want to use four strand "brass"? What are benefits vs traditional 7 strand stainless? I use nothing but linea from Tom.

[Massimo Rimoldi]

Hello.
I do not think the lines are brass.
From the Ukraina it is possible to obtain 4 strand lines in carbon steel brass coated , probably the one who translated the description was not accurate.
These are significantly stiffer than stainless steel, but stronger.
These lines are widely used for combat and by stuntmen from Eastern Europe.
Obviously maintenance must be more accurate due to potential corrosion.
However (in this case) the price does not seem appealing.

After seeing this I ran up to the local hobby shop and bought a set of "Sig" 70' x .018 for $12.00.

[Randy Powell]

I'll make my own from McMaster-Carr cable. Thanks.

Dear All

Here in Brazil all top fliers use Ukraine lines .
I bought my from Yuriy Yatsenko (but I´m not a top flight  very very bad flier)
The lines are different .
when you pull the lines the normal lines have flexibility , these Ukrainian lines  is very rigid not elastic .

Sorry my English is difficult to  explain

thank you

Don't think you'd see a few of the stretch prone "stainless" lines mentioned above used at the W/C's 
let alone "Sig" probably worst of the bunch.

Hello.
Many thanks to the administrators who missed me on this forum.
I very carefully read all the statements of the participants of the topic Ukrainian Lines and I really want to answer all questions since I am the manufacturer of this product. All lines are produced only by my hands and in small quantities. Before winding the plastic coil, each of the two lines is checked by a force of 22lb (10kg) for a diameter of 0.015in (0.38mm), 30lb (13.5kg) for a line with a diameter of 0.018in (0.45mm) and 40lb (18kg) for a line 0.014-0.016 in(0.36mm - 0.40mm). One line of carbon steel coated with brass withstands a tensile strength of 60lb (27kg).
Lines ready to use are produced of such length - 42-50-56-60-65-66 feet.
Kit sets of lines .015, .018, and .016 are produced of this length - 70 feet.
The lines covered with brass from the effects of moisture darken over time, but this does not change its characteristics. I, and my friends, all the members of the national team Stunt of Ukraine (my friend Sergey Solomyannikov, the owner of the World Cup F2B), and all the members of the F2D Combat national team of Ukraine, we use only brass 4-wire lines. In 2017, I personally flew all year on a single set of brass lines and performed 450 flights on the Stunt  model with a 76 Stalker engine. It is a very powerful engine and we have very large aircraft models, and in very strong winds we fly only on the strongest lines that can be for today.
I'm very sorry that the price for the product that I installed on Amazon you all think is very high. I very carefully listen to criticism in my address. If you think that the cost of the product is very high, then write me here on the forum or me by e-mail. I will definitely listen to you and set the price of lines for Amazon less. It is very unfortunate that Amazon for the storage of goods and free delivery removes from my price 4.5USD (15% tax) + 2.41USD FBA FEE. Transfer of the line from Ukraine to the USA - $ 2USD . From the purchase of goods, I have only 21.08USD.
Who wants to test Kit sets of brass lines and write the result of the tests on the forum - write me your home address to the post office and in 5-7 days receive them for free.

Thank you very much for your attention.
Sincerely.

Ruslan Kurenkov,  knows his "stuff" these guys don't fly profile Ringmasters 

[Chad Hill]

The Ukrainian F2d combat lines that Mr. Kurenkov speaks of are much stronger than anything comparable we have here stateside. The length of the 2 individual lines are always virtually identical. Lines can be interchanged time-after-time with no control adjustment required on the airplane. I would assume that the same is true for stunt type lines.

[Ron Varnas]

Experience & logic prevails hoorah 

[Ken Culbertson]

After seeing this I ran up to the local hobby shop and bought a set of "Sig" 70' x .018 for $12.00.

You have a local hobby shop that knows what lines are?  Wow!

[Paul Walker]

I believe these lines are more about stiffness than strength.

The "feel" like 18's, but are only 16's. Better aerodynamics and better feel.

The average sport flier need not spend that much money, but competition fliers might benefit.

[Randy Cuberly]

With only 4 strands but higher tensile strength there would theoretically be less compression in the cable which probably translates to much less "spring".  That in my humble opinion has to be a good thing for real competition fliers!

I want some!!

Do they "handle and wrap" in the same manner as the more multi stranded wire or are they a lot stiffer to deal with when wrapping the ends?

What about the fact that they are .016 and AMA rules require .018 for 64 oz and heavier aircraft?  Problem???

   Rusian - do the .018" lines actually measure 0.018?  I ask because I got some Ukrainian lines in the past that were smaller than a true 0.018 in some directions. For airplanes over 64 ounces, we cannot use them if they measure under 0.018".

     I have flown on the .016 lines and found the same as Paul, they were distinctly more positive in terms of feel than the usual 0.018 7-strand and much better than the .018 19=strand. But they are illegal for competition for my airplane (and likely future airplanes).

Hello, friends !
I am very glad that I have the opportunity to communicate with all members of your forum.
There are athletes I did not know before, but there are athletes I know very well about achievements.
Stainless Lines that we produce (command controllineparts) are not really Ukrainian. Brass lines are produced at a large plant in Belarus (200 miles from Kiev). In Ukraine, only the final product is produced. Before packing, each separate line ready for use, after crimping with copper tubes, is tested by me personally for the strength of both the cable itself and the crimp tubes and eyelets. During the test, a marriage is identified which is utilized. Only after the test the line is wound on the reel, packed and sent to the buyer. For me, as for the pilot stunt model, the most important thing is the quality of the product. I guarantee with the utmost responsibility the highest quality of my products.
For the tests, I sent to my good friend in the United States 10 sets of brass rope 70' long and 0.0145 (0.36 mm) diameter. This is the lightest and most durable (60lb) rope for Stunt model for today. At World Championships where American pilots participate, the FAI rules allow such a cable. I want to send it for testing to top American pilots like Paul Walker and Brett Buck and other pilots who participate in the discussion. For this, I need a delivery address and everything. All these 10 sets I'm ready to send free of charge. The delivery time is 3-5 days for USA.
The length of the cable 42-50-56-60-65-66 is from the eyelet to the eyelet.
If you have any questions about the products of the controllineparts, I will certainly reply within 12 hours (a big difference in time, when you have a day - I have a night).
Thank you very much for your communication.

   Rusian - thanks for the offer! I have tried the lines from the Yatsenkos, I presume that these are similar.  I will have to decline, I think, unless I am misunderstanding the issue. I would love to be able to use the brass-plated steel lines for the performance advantages, but unfortunately, if I understand correctly, they would not be legal for me to use in competition.

   What you may not know is that the strength of the lines is only one of the factors for the legality of the lines. The AMA requires the lines to be a minimum diameter as well. The diameters are based on the commonly-available US line sizes - 0.008", 0.012". 0.015", 0.018" and 0.021 inches. They are chosen based on the model weight, and the industry stndard strength of stainless-steel 7-strand wire rope.



     Unfortunately, I would require 0.018" diameter lines (as measured - and they do measure them) for my models. The .016 lines would be legal but oversize for models less than 64 ounces, which might be worth doing for some near the top of the weight range, but are heavier and have more drag. The .0145 lines would only be usable for models less than 40 ounces, for which they are quite a bit oversize.

     Almost no one (or maybe literally no one) reading Stunthangar today will ever fly in a contest where the FAI rules are used, so that is the issue people are having with the topic.

    If I understand your comment correctly, the .018 line are "Fly By Wire" cables from Cablestrand, not the brass-plated steel lines we were discussing previously. I have already tested those, so no need for additional experimentation.

A few guys here in New Zealand use them. I believe they have much less stretch than stainless lines.

I have been using PAW Staystrate 3 strand lines, which are made from fine piano wire and have been run through a solder bath. They are awesome, no stretch and they do not bind up at all.

[Mike Scholtes]

Hi Ruslan:

My competition model is 52 ounces and flys on 60-foot .015 multi-strand lines, so your brass-coated 60-foot .016 would work for me.

The advertisement on Amazon (posted above) says the eyelets and crimping are installed by the buyer, but your comment above says the lines are sold ready-to-use with eyelets installed. Can you clarify which is correct? Of course I prefer ready-made ready-to-use.

I would like some less springy lines and yours sound like a good product.

Hi Mike
All product descriptions were originally generalized, as on the back of the product packaging. Now my good friend American is editing them to make it very clear. All products which are a Ready to Use with installed eyelets and crimp copper tubes (very clearly seen in the amazon photo). The Control lines of control that need to be crimped most sold under the name Kit Set 70' (.015/.016/.018), there are no eyelets and copper crimping pipes and are inside the package (very clearly seen in the amazon photo)
I'm sorry that you did not understand, it's my fault. I apologize.
Regards

I've ordered a set from Amazon to try.  Most of my airplanes are typically under 60 oz.

Incidentally, the lines from "Amazon Prime" cost $21.50 shipped!

They are 70ft long but are not wrapped or prepped!  That's Ok for me because I typically use lines that are different length than those prepared by any one anyway!

The idea that they are less springy is most attractive to me!

PM Me and I will send my address.

[Mike Scholtes]

Hi Ruslan: I went to your Controllineparts website and found the ready-to-use 60-foot brass-coated lines. I intend to order a set. I think your price is reasonable for something made in Ukraine by hand and delivered to the USA. This is actually pretty cheap for something so important!

You probably know we have a lot of Ukraine model flyers here in Northern California, mostly in free flight. Some aeronautical engineers have immigrated for jobs here, very knowledgeable people.
