Stits Covered 1/4 Scale Cub
I did some looking around to try to figure out how much of each of the materials I need. I don't really want to read for hours sifting through other threads.
When I called stits, they told me it would cost about $300 to cover my cub, and I thought that sounded like wayyy too much.
I think it would cost that much if I went ahead and put the UV protection paint on and everything, but I don't think that's necessary.
So I just want to double check that my bill of materials will be enough to get my Cub covered.
4 yards Lite Fabric (I believe it's 60" wide)
1 Pint PolyTak
1 Quart Poly tone (J-3 OEM Yellow)
1 Qt Poly brush.
Is there anything else I'll need? MEK for thinning the poly brush for spraying?? Where would I get this?
Thanks in advance.

Also, light kits...What would be a good light kit for this? I saw some on Ebay for like $30, but I don't think they had the light controller.

Chip Mull at F&M has always been right on relative to his recommendations for how much paint and covering would be required. I haven't ordered in a while so I can't quote exact amounts but 4 yds sounds about right for a 1/scale cub. However, 1 quart of the yellow will not suffice. Yellow is notoriously hard to get a good even, opaque color with. I think it is usually recommended to put down a coat of white first to help (although this might not be needed if you don't put down the UV undercoat), but in any case you'll need at least 2 quarts of yellow. I normally clear coat as well but I guess that's not required. Be aware that the UV undercoating also serves to do much of the weave filling. If you skip this step, you may end up with the weave being more pronounced than you would like.

I thought poly brush was responsible for filling the weave?
Thinking I might just use SolarTex. How much of this will I need? Is Solartex the one that a lot of people use instead of fabric/dope?

You can even scrub marks off the polytone with bleach with no effect to the finish.

Do you have experience with painted fabric coverings of any type? Do you have a well ventilated area to work in? I hope you are not going to attempt this in a house as the Stits paints have an incredible odor and the MEK base solvent can be explosive. Are you going to spray or brush the finish coats ..... spraying works best for most people.

Say no to solartex. You are on the right track using poly lite. I use the poly-tak around the perimeter, shrink it like they say to, One thing I do that is kind of cool is I glue threads to paper and cut it to simulate the stitches, then cover it over with the finishing tape. I use stix-it to adhere the rib stitch strips and the finishing tape then seal the whole thing with 2 or 3 light coats of nitrate dope. I like to spray the coats with it thinned enough to be sprayed. about 70% dope and the rest lacquer thinner. I don't fill the weave because the primer I use fills it adequately enough for me. I use Klass-Kote epoxy systems so, even the primer is a two part deal.

Yes Solar-tex is less expensive but the quality of the poly lite job is worth it in my opinion. The Klass-Kote paint for my 1/4 scale biplane cost is right around 200 bucks...just for the paint, but when I'm done it will be show room quality and nobody on the planet will have one just like mine!

The temp meter - are you just talking about an IR thermometer? I do have one of those if so.
I don't really care to do the pinking or anything fancy, unless it's recommended for durability. I'm not trying to get any more scale than it's an airplane and it's painted Cub yellow.
I don't think the UV protection would be necessary because it's not like it's going to sit out in the sun day after day.
I work in the aviation industry and my coworker uses Stits on his full sized planes and he said the UV layer shouldn't be necessary. He told me just just poly-taks, then poly brush the first layer of dope on, then sprays two more layers after that.
I will be working it in my garage with ample ventilation.

Polyfiber is the same as Stits, no?
Did you use all of the different coats of paint and do pinking etc?
Basically I'm just looking for the bare minimum...What is going to get me in the air? My only requirement is that my airplane flies and the paint looks OK.

Yes, I have done a few by this method.
There are several steps to the Stits/polyfiber systems. If you are new to the hobby then I would consider another alternative. If you have been doing modeling for a while then maybe give it s try, It is a far superior finish for aircraft but requires patience, time and $$$.

I have done a few with the Stits system as well. Stits has a nice tutorial on their site, I recommend reading it, the polyfibre is the same as polylite. I recommend Sig Stix-it for attaching the fabric much easier than the polytak, no the polyspray is not necessary, this is all I use now and have been for several years. Here are a few models I have done with it.

You can use MEK to thin the products (polytak and the paints) rather than buying the expensive reducer and to clean your spray equipment. Get gloves to work with any of the "poly" products or MEK. Nitrile will dissolve, powder-free latex are not entirely impermeable to the solvents but easy to come by and better than nothing. I use a disposable 3M respirator when working with the stuff. About $25 and lasts for a year or 2 if you keep it in a sealed zip lock bag. Don't underestimate the potential nastiness of the fumes.

One other thing, don't go over about 280° when shrinking and watch it as you go. This fabric is very strong and if fully heated will break frame work. The fabric will shrink about 10-12% which is a lot and make's compound curve's such as the Cub's tail fin a breeze. This fabric will not wrinkle or deform after it is finished such as most other hobby grade covering's.

Wow, great input everyone.
Thanks very much.
So the main components I'll need...
4 yards Lite Fabric (I believe it's 60" wide)
1 Pint PolyTak or Stix-it
1-2 Quarts Poly tone (J-3 OEM Yellow) (I will try to calculate based on 1 gallon covering 200 sq ft
1 Qt Poly brush.
MEK for thinning. (Does this take place of the Poly dope 65-75 reducer?)
Thanks again, the input is much appreciated.

One tip for any CUB yellow user. This seems to be the most mis-matched color in the world. I have sourced paint from multiple vendors in Dope, Stits, Klass-Kote, automotive Poly-U and hobby sources and rarely will any of these paints exactly match the others. Point being, when you source your paint, use the same single source for all the paint you will use. I've had the best luck with Klass-Kote as it seems to work well over fabric (is flexible in thin film thicknesses) and solid surfaces such as cowls, etc. Coverage is very good and cost is reasonable.

I don't understand why you want to go with Stits if you aren't going to do a lot of scale detailing. If the goal is, as you said, just to get it covered and in the air as quickly as possible, you won't see many of the benefits of using a fabric system. Do the plane in pre painted Solartex and shoot a coat of clear on it, then paint the stripe down the side and put the decals on. You can have that all done in the time it'll take just to apply the fabric with the Stits system. And Solartex does hold up fairly well. Yes, it will need to be reshrunk from time to time, and it will eventually start to come loose at the seams. But for a practical everyday flyer, it's the way to go.

I don't want to have to re-shrink and re-seal edges. I want something that's more durable than iron on. It's not about getting it in the air as quickly as possible, it's about getting a decent covering on and not spending forever detailing something out if I don't really care about a 100% scale look.
Maybe if I had more time and nothing else going on I'd detail it out, but I'm not in that phase of my life right now.

The Solar Tex is far inferior to the polyfiber in every way. Polyfiber applied properly is drum tight and very tough. Solar Tex is much more flimsy and may need to be shrunk again with handling and changes in temperature. The iron on adhesive is poor compared to the bond you get with the polytak.
You can even scrub marks off the polytone with bleach with no effect to the finish.

If you look at my models you can see a Stampe that was done in white Solartex and orange Worldtex and a Corsair that was done in white Solartex painted with Rustoleum over a white Towerkote primer. The covering stayed tight as long as I had them and was very easy doing compound curves.

When you're done, your plane, fabric, and paint will be good for 20+ years.
Couple of notes. Subsequent coats of paint melt into the previous coat. So if you get dust or something in your paint, when its dry you can pick it out or wet sand it out and when you do the next coat, you'll never know it was there. Also, if you get a run, you can carefully keep misting it to keep it wet and it will lay down to a large extent. Be aware this also means that MEK and/or acetone will remove your paint job (and Polytak as well), even when its fully dry. Other than that, its impervious to glow, gas, and electrons.
