Fan Fold/Bluecor Tips and Techniques


Hello All,
I've been lurking on this site for a little over 2 months and I have to say that I'm hooked on RC Planes.
Foamies especially.

I picked up some Bluecor on clearance yesterday (1/4 inch, film on both sides), and it's burning a hole in my hobby table.

I've read several wonderful tips about using bluecor scattered over several different threads at this forum.

But they are all over the place.

And I don't see a sitcky for FFF/Bluecor tips. So I thought I'd start one.

So how do you work blueor?

how do you bend it or fold it?

How do you make curves with it?

What is the best way to make wings with it?

what tips do you have for access panels and support rods?

How do you get the film off?

How do you paint it?

how do you cut it?

how do you sand it?


So what will be my first project with bluecor?
Well GO_RC's Millenium Falcon kit of course.

So all you sage experts, please post your tips for bluecor and help us newbies out.

thats a lot of questions in one thread
cut= with a razor knife (unless you have big $, then a laser cutter)
sand= like very very soft bulsa,
film= only remove it if it is needed, it stiffens up the board
access panels= nio mags
bend it=hot, hair drier or ziplocks with hot water in a 'mold'
curves=hmm depends, like a circle, razor knife still works, like a dome, pie slices glued together
glue=foam safe superglue, but if you have time gorilla glue or any polyetholine glue(spell that) its a water proof outdoor woodworkers glue, get diff names at wally world home depot, anywhere

Thanks Zorcy!

One question, how do you sand like very soft balsa?

I'm a display model refugee and sanding was one of the things I was HORRENDOUS at.

afraid i have not painted yet, its kinda gutsy for a falcon. an easy one is the STC. and very forgiving to crash. the hydrofoam is a fun idea, but i have only built in, i have not put any power to it yet. if you are going to build, might as well build the cd rom motor too. that is another year of research, so cheat and get a kit with directions.

get a sanding block, or several, many grits, glue the paper to the block (disposable lumber) 80 is to be used like a saw, it CUTS away foam. have a hand vac there too, lol, you will see. most work, that will look good, will be cut, cut at a beval or formed with heat. most foamies are built to fly, crash and repair. sanding is more to fit parts together

Painting blucore foam


Paint=acrylic cheapy paint at hobby craft stores. A bottle usually costs about .89 cents Cleans up with water. Be sure to let it dry real well before touching. I draw my outline with a sharpy, (try to match the color of the paint) and then use a small paint brush to paint the plane. This one took about 1.5 hours, (includes two stripes on the bottom)

Lowe's on Austin highway.
It's on clearance for about $16.

I'm seriously thinking of going to buy a second unti of it.

thanks for the link Zorcy.

Does the scoring technique work for deeper curves on bluecor?

The Lowes in Kingwood, Tx had some 1/4 inch a couple weeks ago. Bought two bundles. There may still be some left. Yup, $16.
Painting -- I found that using Minwax Polycrylic water based to seal the foam very well. Well enough that I sprayed some Testors and some Krylon on a test article with no bad affects.

Strange Vy, I wonder why it isn't used for painting more. On the otyher hand, Krylon on unprotected foam did cause problems. The area with Polycrylic was protected.

yeah the water based polyurethane does great at sealing the foam .. i put it on over the paint also so offer some protection to the paint..

that polycrylic sounds like a good idea.
