Hi Guys!!
No pictures today... but the progress is coming...
The pilot place, called ... cop... sorry is done, hope the pilot fits.
lower wings tips drying in the template.
elevator ingles glued and alignment.

After Thinking and thinking the finish will be clear on fling surfaces with some orange or purple trims... the design is so beautiful (Thanks George) to cover it with solid colors. i will try to cover with Microlite, hope it be as easy as tissue covering.

somewhere i read that you can cover with the clear film used on printing workshops to cover magazine covers and posters. i donīt remember where, but they said that it has glue that reacts with heat. close from home there are many of this workshops, i will ask for a sample. lets see.

Yes CG, doculam - document laminating film - is excellent for clear covering. My Triplane is covered in that and then has lightweight tissue applied over it before spraying with the scale colour.

For an good example of a model covered in laminating film and then tissue on top see http://www.rcgroups.com/forums/showt...=cloud+snooper

In post number 50 of the above build log you will find details of a UK supplier of the laminating film this builder used, which was 42 micron thick matt finish, www.bindingsupplies.co.uk. I am not suggesting that you would get the film from this supplier, just that you can look at the material and know what you need to find at your local suppliers. I think this covering would be excellent for the Tom Tit wing and tail - either just on it's own for a transparent look or with tissue on top for colour. As the builder of the Cloud Snooper says, it is one of the easiest heat shrink coverings to work with.

I just had look at that site, and was initially shocked at the price - until I realised that it was Ģ60 (inc VAT and P&P) for 230mm x 150 metres!!! - that's for the 38 micron - they don't seem to do the 42 micron spoke about.

George - what's the weight / rigidity like? It's a good deal thicker that the 10 micron mylar I've used. Is it rigid enough alone - ie could you simply paint over with acrylics?

Learning all the time, learning all the time!!!!

Weight is OK for models from 30" or so up. Rigidity is good, about the same, or a bit better, then Oracover Light and similar translucent films - but it is easier to apply, sticks like **** to a blanket and shrinks better than Oracover Light..
If wiped down with meths you can then spray it with acrylic. Paint adhesion is good, it can rub off on prominent edges after a while (based on a model I covered 12 years ago!) It really is nice stuff to work with and superb on bigger models under Esaki Liteflite. And a fraction of the price of modelling films, although you might have to lash out for a big roll. There are places where you can get it in sheets or smaller rolls though.

Looking great CG. How do you manage to build so fast??? Don't forget the struts! The undercarriage will be OK that way round I think.

Thanks George!
well, just working a couple of hours every night... and i be keep it slow and making time for the motor arrival.
No, tomorrow i will get some 1/16 ply for struts. and look around for covering ideas and materials.
The wood work is like 90%, just missing to cover the button of fuselage, Struts and cowling.

now i get some waterbase poly varnish, and if i get some doculam i will make some test on a ugly guillows wing. i will try to cover with doculam/tissue.

I used water based varnish on mine because I could not get any dope and thinners at that time; it works fine but given the choice I would use dope.

It is a very good idea to try out any materials new to you on an old wing or specially made test frames.

Hi George!!
I found doculam, 27ĩ, matte finish. So, so cheap, 30 mts 60 cm wide for 8 USD, i will cover the flying areas, and then, i will need help to cover the areas with tissue.

Presumably it's much the same as applying tissue over mylar - a technique about which I recently interrogated the experienced! To save people's fingers, I asked the same questions, so check out Raf_Bob's answer in posts #172 & 173, and Sundancer's post #174....

The main part is to apply the tissue wet!!

Glad you found the doculam CG, sounds like a good bargain! Thanks Colonel for nipping in with the links, you obviously get up earlier than I do, but then I am retired!

You definitely need to cover with the tissue wet for best results CG, then all those little bubbles will vanish as the tissue shrinks. Have a try on your test wing. I hope your tissue is OK, it needs to have wet strength and shrink properly, a lot of tissues are just no good for this. I only trust Esaki now.
