Thanks for the videos. By far the most informative and helpful in my search. I’m getting ready to cover my first plane, a 1/8 scale balsa Sopwith Pup electric motor and I think the poly lite with a coat or two of polycrylic will be the best combo. Just ordered a couple yards from Stits. Best regards.

Here is another experiment I will try on the PolyFiber - since it starts shrinking at 225F and water boils at 212F here is an interesting experiment I will do for sure: heat water to almost boiling, add the new Rit Dye More polyester fabric dye on it (color of your choice) ... then immerse the PolyFabric and will see how it takes the dye. If it works then we will have an amazing selection of colors to play with ( Rit DyeMore lines of dyes) .. Just a thought on what's coming to my mind and experiments once I receive a yard of PolyFiber .. This will be "huge" for antique models and free flight etc .. where the fuselage is one color and the wings are another .. usually a green / yellow or blue / yellow combination would be amazing ..

I really appreciate this video, im newer to rc planes and i prefer to build myself so im still doing lots of research, ive done a few planes in monokote and ultracoat type stuff and i don't like how fragile it is. Im building a 1:4 cub wich is going to be my crash course on cloth covering.

James! Cannot thank you enough for this bit of experimentation that you did for us! It's been over 40 years since I've used fabric on a build-up and wanted to see of I could go down the Polycrylic road this time around. My only question is: did you heat shrink the Koverall prior to applying the Polycrylic or visa versa, or no heat at all. Please advise and many thanks for your efforts!

Hi James, Nearly forty years ago I had to learn dope & fabric as part of the curriculum to obtain my A&P aircraft mechanics' license. We first learned how to use Ceconite and later Irish Linen with nitrate dope. I've never used linen or any other dope and fabric on my RC planes but had wonderful results with SolarTex filling its weave completely with Aerogloss (satin) butyrate dope. Makes a wonderful dope & fabric-looking finish. The nicest finish I've done is on my SIG Four-Star 40! Have you used SolarTex and if so, how did you like it? Seems they have gone out of business recently but thankfully I have three 5-meter rolls in reserve for my Balsa USA, Bristol M1, and a few other smaller planes.

I have a roll of Solartex but haven't used it yet. It's not a film like the ones you mentioned, it is a fabric similar to the old Coverite Fabric I believe where the adhesive is already built into it.

Nitrate dope is the strongest lightest best way to apply Koveral, paint your model that if fuel proofing is needed use 2k epoxy clear spray can

Thanks for the videos, going to place an order for the sig koverall, but have a question. The engine I am using is nitro so I would use the fuel proof supercoat on the entire plane, instead of the nitrate? They make it clear so I can paint it myself. I will have to find out what type of paint is compatible with this fuel proof supercoat, unless you know. Thanks Dave

Properly applied wet covering with Dope should not need heat .... if you need to heat it - then its not applied correctly and will likely sag later. I think a better demo would have been to apply each material with exact same systems to compare results. With what is done here ? It is 3 different systems and also uses heat .....

Polycrylic is NOT fuel proof - saved you some time and frustration but I really liked your comments on the PolyFiber so I will give this a shot as well - thank you for sharing this video.

I recently purchased an old Sig J3 Piper Cub and it is a fabric covered rc plane. I want to paint over the yellow and make it look like my Dads old scale Aeronca Champ which was two tone, Beige & Green. How would I go about prepping it and what type of paint/epoxy should I use??

Before applying the Polycrylic on the polyester dress liner sample, have you attempted first to shrink it with heat ?

@@jamesboatbuild Thank you for both replies - so, is it safe to assume that when you shrunk the polyester fabric liner it actually did shrink as expected, BUT the application of polycrylic made it saggy ? This detail is important for me as I plan to alter slightly the sequence - meaning: after shrinking the polyester liner, I will apply a couple of coats of nitrate dope, and THEN use the polycrylic to fill the rest of the wave. I have a "hunch" that the nitrate dope will "lock" the fabric and won't allow it to sag .. Just a feeling I have .. But I did want to know if the liner did shrunk "tight" before you applied the polycrylic. Thank you once again for your time. Those experiments and its variations are PRICELESS ..

Thank you very much for your reply ..One more interesting experiment would be to use Sig Stix-it on PolyFiber Lite as I prefer the convenience of heat activated cement glues with an iron. I will sure give PolyFiber a try along with Stix it .. and for sure use Polycrylic to fill the weave after I tighten the fabric with the iron. Thank you so much for sharing this video with the rest of the modeling community.

I haven't used the non-certified "light" poly fiber, but from memory the certified poly fiber achieves maximum strength when shrunk at 350 degrees. I think you start at 225F but then end up at 350F.

I voted it down simply because you went about using the materials without any regard to the finished results. Therefore one is left without accurate information about using the materials, or of what results I might expect if I used them properly. In your first video it sounded as if you might take this demo more seriously, resulting in a tutorial worth more to the real world of covering using these materials. No one should rush, or haphazardly approach the final stages of finishing their model. It would be a huge mistake after spending your time building the model you want to fly and be proud of.
