Jim,

Very nice... very very nice. I think I should put that up on my "working with balsa" page as a prime example of just how effective doculam can be (okay, I won't really, but it would be an excellent example).

Paul.

thought i'd post a couple of pics of the Elipstik 460. i painted the inside of the doculam so when it belly lands, none of the paint will come off. the stripes were done using wet news paper and the shield on the bottom was paper templates.
if your going to paint the "glue" surface, make sure you keep the the paint to a minimum. the glue has a hard time getting throught the paint.

My latest doculam covered plane is the Seether -

The black/blue parts are sign-makers vinyl scraps that I raided from their bins while they cut out the 'Seether' lettering.

The wings/stab are covered in doculam, it definately makes for a much better flight performance compared to raw wood.

I should point out that one really great thing about doculam/laminating-film is that you can exploit its high temperature resistance to make way for a new method of bonding carbonfiber tow to the wings.

What I did was lay down a 1/2" wide strip of hotglue (smeared on while hot, spread with a ccard, masked off with masking tape), I put the CF tow down on the strip, apply the doculam over the top and turn the heat and pressure up. The result is a nicely wicked hotglue+CF mix and it's very flat (I do have photos available of the process).

Paul.

Clear it is a bit over solite. Painted it's probably close to solarfilm, depending on how much paint you use

btw, I updated my Doculam/laminating video - it's now in flash video format, so you don't need a codec.

Heres a Tiny-X that I covered with Doculam on the tail and ailerons. I dry brushed the inside (adhesive) surface of the Doculam in a crosshatched pattern using red and white acrylics. Then I covered the model with the painted Doculam. I was happy with the results and the paint will never come off as its on the inside.

Gerry, that looks stunningly good.

What did you use to make the doculam red?

Paul.

I only covered the tail and ailerons with the dry brushed Doculam to get the crosshatched pattern. The wing is covered with one of the lightweight mylar films that came as transparent red (I forget which brand). I thought the pattern on the painted Doculam was a good contrast to the red wing covering.

Gerry,

Darn, I was sincerely hoping you had found a great way to make fantastic looking dyed doculam (transparent red). Your crosshatched feathers strangely remind me of a candy-stripe rose bush I had

I was just discussing this same thing with one of my club members. Anyone have a practical idea of what could be used to 'dye' doculam?

Just a quick question. Are most people using the clear Doculam or the frosted for painted models and is there any difference between the two for painting?

Are there two different types? Doculam is frosted when first taken off of the roll, but turns clear when heat is applied.
