Beautifull workmanship. Something you don't see too much of today.

Here are some photos of a GWS Formosa that I covered in Solite back in 2005. I prepped the foam with "light" latex spackle and just ironed the Solite down on the foam. The Solite is shiny & reflective like a new car which made it hard to take good photos of.

I still think a Tiger Moth would be strange in shiny film finish ?

It could probably be dulled with a light spray of flat clear.

I looked up some examples and while some guys have gotten some great results with film, there still seems to be a foam bead texture showing through on EPS models that have been covered with film. Additionally, you run the risk of swelling the beads with heat application.

I'm going to try Japanese tissue or silkspan with WBPU. This seems to be the best way to cover the foam texture without adding too much weight. I'll experiment and report back here.

Check out this Ultrafly P-51 build thread to see what is achievable:

For referrence, here is a close up of the Ultrafly EPS foam texture:

Matt Halton seems to have completely eliminated that texture!

Nigel, you got any pics of your Solartex covered models? Does it completely hide the foam texture (assuming you covered EPS-type foam with it)?

My Big 61 powered Biplane has foam used in the wing to complete repairs ... ribs and sheeting. She was smashed in a vertical into tarmac after elevator failed in an inverted fly-by !!





For me - bipes like this and the Tiger Moth are fabric covered machines and deserve similar in model form.

The real beauty of Tex is it's fabric finish and it's ability to accept any paint ...

Another method if you aren't looking for strength, is paper. Where light glass cloth will conform to the foam, a good thing for bonding/strength, paper tends to bridge over the foam. Will hide a lot more of anything you missed in sanding.

I glassed the bottom of the wing and inside fuse on my E-Flite SuperAirliner. Outside of the fuse was done with newspaper, wing with of all things Christmas wrapping paper.
Coat of WBPU, lay down the paper, nother coat of poly, squeegee off the excess.
Light sanding, coat of primer, sand, paint.

Check out the reflections in the paint. SMOOOTH!
Stunningly beautiful model.

I use a technique similar to your bonding process except I use white glue thinned with 3 parts water to one part Elmers using "silkspan" (not silk).
It takes a couple days to dry completely but it sands well and "takes" color coats well.

I'll have to investigate the water based polys and find what seems applicable.

A guy in our club did a Balsa USA SE-5 using WBPU as the base coats over "Tex" material and then shot that with two thinned coats of regular household interior latex.
It's one of the best finished planes I have ever seen.
It's a heavier process than what's being discussed here, but I was impressed how well it "flowed. Not a seam or overlap could be detected.

If you want to simulate a fabric finish using the newspaper and wood glue method, brush the glue on in the horizontal direction on the first pass, then in the vertical direction on a second pass. The criss-crossed brushstrokes will look just like fabric. You want to glue to be fairly viscous -- not too watery -- so it leaves the brush stokes. ModPodge also works great.
