- How I covered the right wing of my Avid Flyer HH with ORATEX UL600. Note that this in NOT an ORATEX instruction film, it just shows how I did it...
The only intention is to give an idea of the work required to anyone considering using ORATEX on an airplane project. If this is not your case - watch another movie, this is a very boring film.
More information on using ORATEX and more can be found on my blog: avidsimonini.bl...
I have (without permission) borrowed 2 tracks from Carlos Del Rio's album Flamenco Y Clasico, "De Fiesta" and "Buleria".
My films are not monetized but you can always encourage me by "buying me a coffee"... www.buymeacoff...

Hi Fred, Many Thanks for posting! Very Nice ! It illustrates so well the correct use of the tools, with the FeltBlade, The Heatgun, The release Paper, the Iron, Even the Roller with the Handle! Your workmanship look superb and I love your choice of music (again!)
Great Video! Best Regards from Alaska!

Yes, you guys are getting some product placements totally free of charge... It's on the house!
It is good to get the confirmation from you that the methods used appears correct, thanks for that!

Definitely not boring. Beautiful wing. Thanks for posting this.
Great job Fred. I am going to use Oratex on my next airplane covering. I recently replaced the fuel tanks on my Kitfox from 1992 and had to use the original Poly Fiber system for patching two rib bays. Took about 25 hours and the cost of the toxic MEK based materials exceeded the Oratex cost for sure. Plus I had to wear a respirator while completing at least 20 steps. Poly Fiber is good, but I think Oratex is the future.
not boring in the slightest, very well done Fred. Thank you!
Very 👍
Hi, Frederik. Thanks again for a great lesson in covering. I also enjoy the music very much.
If anybody is going to Oshkosh at EAA Airventure (2019) and has an interest in this, we will be there with our booth #300 near the Control Tower. Right beside Hangar A. Right on the main road that passes in front of the tower. We will be covering an airplane there again and so we can teach what to do and what not to do at all; non-stop during the whole week. We will also display several Oratex airplanes at the booth, aside of those that show up in Oshkosh anyway...(like the ones competing at the STOL competition !)
Hi Fred, thanks for posting this! As always, your video is educational and entertaining. I'm looking forward to seeing your Avid flying again. I'm about to get mine flying again also. Bryce in Tennessee
BRAVO!!!
excellent
just what i needed to see! Thank you!
Looks great! Nice work! Is there any risk of twisting the wing with the ironing and tightening process?
I don't agree with you at all I have no intention of covering a aircraft with this but this video was fascinating. Well done you look like a pro.
I wish it was a certified fabric my Brother has a Taylorcraft that is in need of covering and this stuff looks intriguing.
Thanks for a assume video.
Thanks Taz Man. Oratex is certified for both light and heavier aircrafts (Oratex 600 for aircrafts up to 600 kg, Oratex 6000 up to 6000 kg). But the certfication might be country depenent. You brother can find more information on the oracover web site or by contacting oracover directly. They are very responsive.
Regards,
Fred
So no need for rib stitching?
Not with 1 inch cap strips and the oratex hotmelt adhesive - and the speed this plane fly! But nothing prevents ribstitching when so required.
how much does this stuff cost anyways? were can it be purchased? does it work on wood as well?
If by "the stuff" you mean Oratex it cost about the same as covering with traditional methods, not by the meter but as total cost. There is no need for any kind of paint job so if that is something you would have paid for you can subtract that as well.
Yes to wood, luckily as most of the surfaces glued to on my wing is wood...
If you go to the Oratex/Oracover (google or go to the link section on my blog, link to my blog in the comment section under the film) you fill fine all required information including local retailers and user manual (downloadable as pdf).
aren't u sposed to wrap the first one around the tube and only trim the second to 1" wrap min.
I still think a couple layers of boat shrink wrap might work
You need to adapt the method to the construction of the wing you are working with. Starting by wrapping the leading edge 720 degrees as it says in the instructions isn’t really a viable option on this wing. Still holding up well after 6 years.
@@fredstork I just finished covering the tail of my kolb with polyfiber. The problem with this stuff is ordering it by the quart and needing another quart and getting hit with A Spruce shipping again and again. I should have bought gallon of polybrush and polyspray instead of 2 quarts. I came up a bit short on what I wanted to apply for polyspray too.
@@embededfabrication4482 not the right video for you if you are using polyfiber… very different technique compared to Oratex
Salut Fred, est que vous avez encore des documentations du Avis Flyer car j'ai le même model d'avion et je n'ai pas trouvé rien de tout. Est que vous me pouvez aidé? merci beacoup Mario
Hi Marco! Send me a mail trough the contact form on my blog avidsimonini.blogspot.fr and tell me what you are looking for. I'm sure I can help you.
Hola te hablo desde perú saludos cordiales, que tela utilisas y donde lo consigo algún contacto seria de gran ayuda gracias
Hi, the fabric is called Oratex and you can find more information on the manufacturer's website www.lanitz-aviation.com/ At the bottom of the page there is link to Dealers and Representatives, the closes for you would be in Paraguay:

Hi Fred, thanks for the video. A few years have gone by since this video was made. How's the Oratex holding up?
Scott Settlemire I got your question just before going out to the airfield so took good look... It still look like new. It is holding up very well. I expected to have to do some heat-gun re-tension from time to time but have not felt the need. In the video description you find a link to my blog. Select only the Oratex posts and scroll down (eventually you need to click "older posts" at the end... Anyway, there is a post on stress testing and aging of Oratex that you might find of value.
Thanks for the update and videos Fred. I’ll be placing an order to cover my Challenger II soon. I will take a look at your blog.
Great video, I will recover my Kitfox 2 shortly.
Did you glue together 900mm and 1800mm sheets?
Hej Peter! Yes that is exactly what I did. There is more details that can be of use to you on my blog. Here is a direct link to the Oratex section of the blog: avidsimonini.blogspot.com/search/label/Oratex
Hej Hej 😀
Some great info there Fred, thanks!
Is the glueing of two sheets an approved method by oratex?
I can’t find any information about that in the manual...
@@Peter_Eriksson You will always be gluing Oratex against Oratex in some places when covering so there is no reason why you should not do it. The overlap is rather large and turned the "right" way so I have no concerns. There is a very nice comment from BetterAircraftFabric (pinned on top) , they are selling Oratex to the North American market and would most certainly have protested if I was doing something wrong...
Some time ago I had to redo the landing gear any it was very difficult to get the Oratex off the tubes and Oratex on Oratex could not be separated... But again, I'm just sharing my experience so don't do this at home ;-)
Thanks for taking the time to answer Fred!. I totally agree with you 😀
Hello Fred! Is that wood wing?
The wing spars are metal and the ribs are wood.
Hi Fred. How did you manage to glue two sheets together (see 0.33) without shrinking the fabric at those points? Surely each time you apply heat to activate the HotMelt glue, shrinking takes place??
Hi Reddogchi ! The glue is activated at lower temperature than the shrinking...
Thanks Fred. Great Video. Can you remember the actual temp that you used to bring together the two pieces (in Celsius)?
I'm considering using Oratex myself but it looks awfully thin....did you find that any cuts that you had to make (for hinges etc) were prone to splitting further?
I don't recall the exact temperaturs... the temperature used is alos dependent on the material behind (wood, steel..) You will need to do your own tests on some samples before starting anyway. But from memory... positioning the fabric (getting the hot melt "sticky") about 50°C, activate the hotmelt about 100°C and shrinking 180°C (those being itron temperatures, heat gun temperature set highter but use at greater distance...). There are instructions and other documentation to downmload from www.lanitz-aviation.com/ there might loso be more details on my blog avidsimonini.blogspot.fr/ (not sure I got into details of exact temperatures)
Oratex is extreamy strong and there is no tendency to rip. I obviously made reinforcement where I had made the cuts as well as, where so possible also hade the fabric glued from behind.
What method to attach oratex
TEGO SUWARTO with a special hot melt glue. It is a glue that looks like white glue, it has no smell and is solvant free so you can work without specific ventilation. I made some of the smaller parts in my home office. It is very clean to work with. You put glue on both surfaces, let it dry and then you activate it with a heat gun or iron.
