Way to go Jon!...Oratex also doesn’t have many color choices and once decided it’s for life of the covering. Off cuts with Dacron can be used for tapes or even peel ply pull for wing tips or molded winglets of epoxy substrates. I still want video series of afforda-plane as soon as u done
Great presentation Jon.. thank you.. looks like you are using the Stewarts. I have always only used Polyfiber and have been really satisfied, but getting the Haz chemicals shipped to our part of the world (South Africa) has become prohibitively expensive. Am going to give the Stewarts water based system a try on the next project.
I've not used Stuarts but I will use it or Oratex on my current build. The owner of Stuarts is a stand up guy. He is a CFI too, signed me off to take my check ride.
A mechanic I respect named Bob Woods always used Stits. Now his shop uses Air-Tech Coatings. He says the main advantage is that it takes less work than Polyfiber or Stewarts. Also it can be repaired almost invisibly.
Uhhh I'd go oratex. As a long time RC modeler I,ve done silk dope, coverite with dope and iron on . The finishing is very finniky!! Things at eavh step can go wrong EASILY!!!! Oratex can be masked and painted if you want to go fancy but quick and easy!!!
Hello Jon. Great video, but.. you missed discussion the Superflite System 7. I'm leaning towards this for my Highlander. Less coats of paint as the UV protection is inside the primer and top coat. Also.. Oratex is super expensive. I have quotes from Superflite for everything but the thinners and it's less than $4K complete. The like to like in Oratex just came back to me at $11.7K! I like the concept of Oratex, but the price difference is crazy huge!
You are correct! My bad. I did miss a very popular system from Superflite. They not only provide fabric but their own system for installation and paint. Thanks for noting this omission.
Great explanation. I am having to re-cover a wing on my Rans S7. The plane was originally covered in Polyfiber, I am wanting to use the Stewerts system on the one wing. Is there any issues with doing this?
The presenter he interviewed(?) in the previous video mentions this: th-cam.com/video/fTpGVa-a9_Y/w-d-xo.html Or try tech@stewartsystems.aero and just ask the company directly, Andy Humphery (new owner of Stewarts System) is an honest dude, he won't sell you something that you can't use.
Stewarts system is a pain in the ass. I'll never use it again. It's finicky and takes a lot of practice to get it right. I'll stick with Polyfiber, dope or vinyl house paint.
You've probably Googled it already, Charles, but searching on _stewart systems rib stitching_ produces a lot of good video. I'm using the Superflite knot on my UL build, can't post links here, but just add this to the end of the TH-cam URL: 1au7zB8aNtQ Also, Jon has posted some good interview stuff with Stewart System's Marty Feehan over the years (an excerpt recently, too).
I believe if you check the MSDS document on Stewart Systems they advise the need for outside fresh air breathing equipment when applying their topcoat.
Just be careful of the "system" you use as some of them don't hold up well to ethanol FREE Autogas. "I'll never use autofuel," you say, maybe not but all it takes it one accident & there goes the paint job or glue adhesion. Also many systems must have epoxy primers as the glues will lift over traditional varnish or different non epoxy paints. Look up the problems with this issue before making your choice. There are many sad & angry folks that found out the hard way. I know a couple of them, so research and read throughly.

This channel is just gold! Thank you for being so informative but not patronising. A lost art. Nice job
Thank you for explaining the various types of covering and process.
It was very easy to understand.
Fantastic! All my fabric questions answered! Thanks for making this video!
I believe the scraps of oratex can be used for patching holes from rocks sticks etc, so they have value especially for field repairs of bush planes
Great overview of fabric! Thanks!
Great Video! Thank you very much!
I love oratex 6000 products, this is amazing as far as we experience

It can be painted

This is extremely helpful!!
That was a great tutorial. Thanks

Learned a lot, Thanks!
Useful basics, Jon!
Excellent review !!!!
Uhhh I'd go oratex. As a long time RC modeler I,ve done silk dope, coverite with dope and iron on . The finishing is very finniky!! Things at eavh step can go wrong EASILY!!!! Oratex can be masked and painted if you want to go fancy but quick and easy!!!
I'd love to see you do an addendum to this with the guys using latex paints. Lots of folks on a budget and see if it really saves money.
Good info 👍 Thanks
oratex wing with cap strips, can be covered and on the plane with only 12 man hours of work. one weekend and plane is flying.
I would go for stewarts since its water base also you can use the scrap pieces as well
Awesome Information. Thanks. What are the Pluses and Minuses over Aluminum ? Might make another Great video ???
Excellent 👍
Thank yòu for knowledge

Have you heard of Oratek?
How that compares to these?
What about stitching? Is it better with cotton.
good info but i like be not a fire risk, be lighter, more protection from punctures, easier to fix in the field, so oratex is best,
What about dope from Randolph?
If u pull Dacron off of epoxied substrates...u don’t have to sand prep for paint or for further adhesion.😎

Yeah you just go right ahead and start that puppy up!
So, with these systems is stitching still done? And could you make a video about stitching?

Oratex for the win...
If you are independently wealthy.
I believe if you check the MSDS document on Stewart Systems they advise the need for outside fresh air breathing equipment when applying their topcoat.
im doing the wings and tail on a loehle sport parasol cost is 4200 for oratex. you couldnt give me the other stuff for free, i wouldnt use it
