Why cover your model with carbon fiber wrap?
Over the past couple of years I have built several of the FT designs and have been having a great time flying (and crashing..) them. One thing I'd always missed was some color in them to show how cool they really are!
I thought about painting but had given up after a couple of tries with the airbrush..
So how do I make them "look" cool??
Well, I recently started playing with carbon fiber wrap or carbon stickers. This stuff is often sold as car body stickers but hey if it's good enough for cars it's good enough for us right?!
Let me start off by saying - this is NOT carbon fiber in any way rather it's a vinyl sticker with a carbon fiber pattern on it.
This stuff has all the right qualities we are looking for: it's light, it's VERY durable, water proof, relatively easy to apply, comes in many different colors and it's cheap as beans! Hell You can get enough vinyl to cover your entire plane in the color of your choice shipped for under 5$!
Oh yeah - and no painting needed!!
So I decided to pimp up my mighty arrow... :)
What you will need in order to do this:
- Carbon fiber sticker or wrap - I got mine in aliexpress at 3$ and free shipping for 127x30CM. Those of you who have no patience for oversees shipping or want to go with the high end stuff can get the 3M wrap. I found it on ebay. I didn't measure but I estimate that I used ~1.5M or 5' to completely wrap one side of my mighty arrow.
- Knife or scissors - both work great. I used my Xacto knife and Kobalt razor blades
- Heat source - I used my hot air rework station on the lowest setting (100C) but you can use a hair dryer or a heat gun
Wing covering vid:
Ok so this is how it's done:
You start by dry fitting the sticker to the part you want covered. While it is possible to cover an already built model, covering individual parts before they are assembled is much simpler. If there are complex extruding structures on the part I sometimes choose to precut them before sticking on the vinyl. I usually draw the part on paper and then trace and cut it out of the vinyl.
In case of the Arrow's wing no precutting was needed:
Once You are happy with the fit, peel the protective cover off the vinyl and position it carefully in place. This stuff is very forgiving so even if you misplace it you can carefully peel it off and retry. Start from the middle and slowly progress towards each side while making sure there are no air bubbles.
Ok. Now we need to go over curves- no biggie. Using a heat source (fan, heat gun, hot air rework station - whatever you have), heat and gently pull down the material. The vinyl will stretch and allow you to go over corners without wrinkles. This also works well for removing persistant wrinkels or air bubbles by the way..
*One word of caution though: do not spend more than 1-2 seconds on a given location or you WILL damage the foam and vinyl
Now trim the vinyl ~1-2 inches from edges and start wrapping it around. It is possible to wrap the whole thing around in one piece with heat and a lot of patience but I usually make a few relief cuts (think about wrapping a gift). You don’t notice them later on.
Here's one finished wing:
Fuselage next - no problem!
Even the firewall gets covered:

Summary:
I see this as a new and really cool way for us to customize our scratch builds. It's simple, cheap and does not require much practice.
Questions? Put them below and I'll be happy to answer them.
Some pointers:
- Get more wrap than you need - this stuff is cheap. Don't get stuck in the middle of your work because a wrap got messed up or you miscalculated how much you need.
- Practice before wrapping your first model - take a scrap piece of foam with a straight edge and a curve and see how it works: where to make releif cuts and how to avoid wrinkels. Try overheating it once to learn how to avoid it.
- Working on parts os easier than trying to wrap a complete model - not saying it's impossible but a part lying flat on the table is much easier to work with..
- Fixing mistakes - of course you're not going to make any but just in case.. This vinyl is very fogiving. You can peel it off and reapply it multiple times and it'll still look great. If you have a scratch or an airbubble use heat to smooth them out or even slice them with a knife. If you still can't get rid of them - who cares! The overall result would still look amazing trust me
- Have fun!

If you assume 100cmx30cm for the mighty arrow (even though I used MUCH less than that) it would be 84g. My guess is that I used closer to 50g of this material to cover the entire upper side of the arrow.

I guess you could peel off or cut out the covering on the parts you are gluing if you are concerned with it not gluing well.

Also, DTF is much heavier where I live so I dont know that I can put any extra weight on this thing..

But it very nice paint scheme and if you don't mind to have a heavy(or fast) plane, this is the way!

Are you buying this stuff where? In Brazil?
Have you used it in a FT Arrow too?
I'm worried that it will become too heavy, I have one made of the kind of paper + foam we have in Brazil, but it's already too heavy (and weak). Maybe with this cover it will become a brick and good only to display :)

Dollar Tree Foam is not available where I live while depron is. Maybe we can use depron now :)

Thanks for taking the time to try this out and post this article.

Would it be possible to remove all the paper from the foam prior to fitting, while it won't save tons of weight every little helps here.
With the extra strength given by the covering it could be possible to remove some foam from the wing itself to save weight.
Anyone any thoughts? I plan on building a bunch of these at the end if the month and would love them to look as good as this but stay light.
