Recovering an ARF Kaos .40
 
Hello everyone,

I have owned 2 Kaos .40 planes before, one built by a friend and donated to me, the other was an arf. The plane flies so great that i believe i will purchase another. My question is this, Has anyone stripped the covering off an ARF and recovered it with a custom scheme? I wonder if it is possible to do so without damaging the airframe.

Has anyone tried this? I believe i will leave the ailerons white (the original coating) and perhaps do the same with all of the control surfaces.


Any input is greatly appreciated,

Alex

is easy to do, i use single edge razors etc and a heat gun to strip the covering, then I follow up with MEK or acetone to remove any leftover pigment and adhesive, I have stripped two so far

Do post pictures if possible. Recovering must be very common.

I bet alot of people have recovered a KAOS but I don't know of a thread realated to that. I sure loved my Kaos!

Here is a rendering of the scheme i've created.Any input would be great!

I am, for some reason, unable to upload pictures to the forum. Just the same I did include the link below which should work fine.

Color Scheme

I like the scheme, will the bottom be different than the top?

Maybe you are already aware, but lay down the color stripes so the air flow doesn't lift them up while in flight. Cover the wing with white first, then lay down the blue, and then the yellow with the trailing edge of the yellow covering the leading edge of the blue, then the red with the trailing edge of the red covering the leading edge of the yellow.

The ARF version of the Kaos is from Tower so it had Mono for covering. As mentioned, using the heat gun will lift the covering but leave behind some of the pigment. Acetone and sand paper will get rid of most of it or it will show through the lighter colors. Recovering an ARF is perhaps the #1 mod people do with them. There is no harm to the airframe.

Imight do red checkers on the bottom but at this point i'm planning on leaving the underside white except for the leading edge of the wing and the tail section will be red.

That is a good point,and that is my plan. I haven't covered a plane in a while and im not 100% sure i do it right. I will be searching for a tutorial on proper covering techniques. I'm ordering the plane now so i still have time to learn some new things.

Anyone with a covering tutorial speak up now!

Thanks everyone.

should be fine with my skills. Thanks everyone for your input. Im planning on having the best looking Kaos at my field.

If you are using Monokote you might look up using the Windex method to avoid bubbling (gassing) noted with this brand. That is,........ when you lay one layer over another layer of Monokote.,

Do a google search here in RCU on "Windex". If not using Monokote then disregard as other brands don't have the "gasssing" problem that Monokote does.

That is a good point. I've heard great things about Ultracote. I hope my LHS carries it.

It is easy to find Hanger 9 carries it. I have used Ultracote a lot myself and love the temperature range it has. You tack without shrinking and then shrink the whole thing at once. Because it has a wider shrink temperature range than Monokote you can shrink it multiple times over the life of the airplane. I like buying Ultracote 10 meter roll so you don't have to worry about the color match because you ran short and had to order an extra roll. I have had this happen with Monokote and Ultracote. The 10 meter roll also gives me plenty of material for another project or repairs. Ultracote is made in Germany and sold under the name "Oracote".

Choosing colors online is too risky for me. Although i suppose in this case it would be pretty easy. Will be calling the hobby shop shortly.

Since the picture function is apparently down, I will set the up as links.

I think they fixed it with the outage yesterday or not. It appeared to upload but you can't view it.

Can I use Windex to hold the trim pieces in place while, or then, apply heat? Instead of waiting all night...


Finally chose a Scheme to go with.Thanks to my family for voting on possible choices.

When using Ultra {I always do} I put on all the base color first and shrink then set the plane out in the hot sun and let it sag. About an hour or so. Then I shrink it again and set it out in the sun. I do this until the covering no longer sags, then I put on the trim. This cures the covering and from then on you can leave your plane out in the heat and sun without getting any wrinkles or bubbles. I do like to use Mono for trim work. Windex first then I just go around the edges, about 1/4 inch in and it doesn't lift off or get gas bubbles.

Why don't I remember this stuff all the time?............. When working with strips of Ultracote use only a moderately hot iron when laying them down or going over them later as an area of ultracote will move on you and create a wavy line which you can never get straight again. Don't ask me how I know this!

My LHS only carries monokote so i'm stuck with the classic. Either way it's the only covering I have worked with and, im pretty sure i still have the "touch" needed to finish the job. Thanks for your advice concerning sagging! I will let the plane bake in the sun for a while.

Thanks everyone,
Alex

ps. Finally the forum is working again. Does that happen often?

Alex, do yourself a favor and mail order the Ultra. I work with them both and Ultra is a bunch easier to work with. I have mentioned the curing trick a lot over the years but not everyong lives in our type of climate. I do most of my building during the summer too when it is still light out at 9:00pm. Not everyone lives in our kind of heat and most the guys build during the winter.

After a few hours of covering, the tail section and the wings are covered. I plan on starting the fuse tonight. So far i'm very pleased with the quality and I've found working with monokote to be pretty easy so far. Time will tell if my work is high quality or below averagehttp://www.rcuniverse.com/forum/js/f.../msn/49_49.gif

Finished covering the airframe and I had a great time. Will be building the model in the near future.

I plan on adding some sort of identification stickers on the side. Maybe a made up number or a kaos sticker.
