Cougar, for flying wires try Aero Scale I believe at aeroscale.com, they are rather expensive but they are scale. they're located in Switzerland

And you know this because, you built the plane, you custom made the hardware, you installed the custom mounting hardware, you have tested the hardware. How in the hades can you possibly know they do not hold anything???

Robert isn't Zor the person Bill requested about a year ago to stay out of the forum due to his disruptions????

Hello Cougar429,

You can use snaps. The kind and size used on winter jackets.
Install them so that the tension force in the flying wires works along the face of the snaps ( not trying to unsnap them ).

You snap them on by hand or with long nose pliers and unsnap them with a 3/16" or 1/4" flat screwdriver.
One end of the flying wires can be attached permanently and remain with the fuselage ( snaps at the wing struts ) or with the wings as the wings are removed ( snaps at the fuselage ).

I can make you a skektch if you need.

Regards from Zor near Toronto.

Many have on many a thread. But he just seems to get a thrill out of throwing idiotic statements around like he knows something we do not. Such as my flying wire's not withstanding force, but yet, he says to use snaps. ROTFLMAO

Hi acerc,

I am being friendly with you.

Yes ... I built a biplane, a Super Skyolt and I made some custom made small fixtures and installed tensioning hardware on all ten wires. I did test the results and the design is such that the wings cannot fold up.

My comment was based on what I see in your posted picture.

Regards from Zor.

You should refrain from comment when you don't know what you are talking about. When you don't know you should ask before giving advice. But most of us know you better than that. This is the last I will speak with you.

Zor

If you wish to consider helping someone is a disruption . . . .that is your privilege.

I am trying to be friendly with you also.

ceije, if this is the place you are referring to, http://www.flying-wires.ch/flying-wires/index.html, I got some from them for my big Pitts. They were not that expensive to me, around $300, but the wing wires were near 4' long.

Zor

Dear acerc,

That is fine with me.

My comments were about a technological subject _ _ _ not about you as a fine person.

On my C-IKOS the lower ends of the flying wires are attached to a dural aluminum plate going across the bottom of the fuselage under the 1/4" hard five ply landing gear mount and just ahead of the landing gear.

The landing gear can be removed or brake off (in a real hard landing) without affecting the flying wire installation. Also both wings can be removed without affecting the flying wires installation. They stay with the fuselage and the interwings struts.

So I do not know what I am talking about. In your picture the lower end of the wires are apparently attached to the low wing root. You did not explain if there is any strong component joining the two sides. It appears to me that the low wing attachment to the fuselage is not protected by the flying wires. If you disconnect the lower end of the wires it makes no change to the strength of the wings at the fuselage.

If your picture is illustrative, I would not encourage builders to build per that illustration.

You do not have to talk to me but you may reconsider some of your writings and again tell the average reader about Zor.

More pictures are available showing the installation on C-IKOS.

Best regards,

Zor

Robert, yes that is the site i was thinking of, thanks forth correction to the web site,

"Your flying wires look nice but they are not installed to prevent the wings from folding up on a high G lift. "

Out of scientific curiosity, what is it that you see, that I don't, that prompts you to come to that conclusion????

acerc.

I am glad to read that some of my postings are making you Roll On The Floor Making AO .

I never wrote that your flying wires are not withstanding force. It is a matter of where the flying wire tension is applied to strengthen the G force exerted on the wings.

A model airplane can easilly be subjected to 20 and even 30 Gs while maneuvering in flight. That was written by someone else and I believe it.

Using snaps is a very convenient way of quickly installing struts or removing them at the flying field.
Of course they are not scale details but they can be installed that they are barely noticeable.
They are installed permanently and avoid the risks of loosing small screws, small nuts or small cutter pins in the grass and the time of installation. I used them on four models ( of which three have been given away to friends when I moved ).
I still have one model with snaps on the struts.

It is not as crazy as you seem to think.

Enjoy,

Zor

Hello Les,

What I see is that the lower ends of the flying wires at the top of the lower wing near the fuselage seem to be attached to the spar(s) at a rib outside of the fuselage.

If it is so as seen in the picture attached to post #17545 then they do not reinforce the wings. The wires could be removed and the model would still have the same wing strength. To be effective the flying wires going from the underside of the top wings near the tips ( or interwing struts ) have to go to the fuselage structure such that the wire tension under high G force goes from one wing tip to the other wing tip.

Same applies to the set of wires upon a hard landing or under inverted flying.

Nice to read you Les.

I've been reading this discussion since I am about to set up the wires on Barth 1/3 YMF. I don't have a choice if I build per plan because kit designer located anchors. The wires from upper wing outer to lower wing at fuse both effectively attach to fuselage. The front wire attaches to a stud that is bolted into fuse. The rear pair of wires attach to wing center section which is integral to fuse. It would be interesting to see a couple free body diagrams with two assumed wing loadings that would show wire loads.

I do have a concern with my kit. It's one of the original offered by Barth some years ago. The full scale Waco had a pair wires on the rear and a single on front. Must have been needed. On my plane the rear pair are anchored by one 4-40 screw with a two ear bracket. The front is anchored by a 1/4 stud. I am worried about the rear one failing, but don't have any good ideas about beefing up the anchor. If anyone else has given this any thought, I would appreciate comments.

Zor, I asked you to leave this page over a year ago. If you make another post on this thread, I will ask the Administrator to remove you from RCU. Got it? Get it!

Mike I believe Peter Barth lost his own model with this anchor attachment and subsequently changed the instructions and all later kits went with two screws , I changed this and went with two eye screws. Peter has seen my instillations and has stated his concern that they may not be substantial but I am convinced that my anchorage is as good as if not more substantial than what was asked for in instructions. Peter Barth is no ordinary modeller and I would have full confidence in his recommendations on this matter.

tmac48, looks beautiful, but may not be the best for something on my scale, nor easy to work with repeatedly at the field, (want something quick, easy and reliable). Still, can you take some closeups of the attach points at the fuse?

acerc

Cougar, if you really want the best of appearance and relatively easy in and out you have got to check out http://www.flying-wires.ch/flying-wires/index.html. I paid around $300 for my 46% Pitts, ws of 96 inches.

tmac48

Couger will have a go at some close ups but not that good of a photographer. The ends with the pins and cotter pins attach to the fuselage and stay there. The other ends attach with the bolt and nuts that attach the struts to the wings, after the initial set up the flying and landing wires do not need to be adjusted again. Hope this makes some sense.( The flying and landing wires stay with the fuselage when the plane is disassembled.) THIS SITE WILL NOT LET ME DOWNLOAD PICTURES!!!!

Hello all,
Stopped by Mason's today to have a look at the Waco the clear cote has been sprayed on and it looks fantastic. The decals on the cowl went on well with a little heat not perfect but dang good.
I'll post some pictures from my phone.
