Nylon or Sig Koverall and dope? Although out of fashion for many years, the results are excellent and give a very strong structure.

Not that hard to source, but it's true it's not cheap!

As Bob says, still available but in limited colours and lengths. A club mate bought some from the website in the link, they take paypal, ..... but yes the prices have gone up !!

I've seen large scale gliders covered in Diatex, and they are now doing a covering with adhesive for modellers, Diacov http://www.diatex.com/-Aeronautical-fabrics-.html

Note sure where you can buy it in the UK though.

Solartex is great and easy to use especially good round complex curves where it takes a lot of pulling and shrinking to shape. However I think it still looks plastic unless spray painted. Silk and dope is the way to go, cheaper than oratex and in my op, the easiest of all to apply and finish if you are patient. Can't find silk? Search for lightweight dress lining for synthetic (polyester) or real sllk. Polyester will heat shrink too, to an extent. For tricky bits, overlaps and edges can be sande smooth after drying and dooing. Difficult to get under 100 g per Sq m. For the best, get Etaki Silk from Freeflightsupplies.co.uk. Only 3o g and doping doesn't add much if you are careful. One coat to apply and shrink. Another to fill, then pu satin varnish to fuel proof. Cellulose paste (wallpaper paste ) mixed thin for allocation also works well.

I agree with Percy, although My experience of tissue or nylon doped finishes is limited to my time in control line early/mid 70's

dope and light sand the airframe before covering then use dope to stick the covering on.......tensioning was done by pinning the nylon around the perimeter. once the structure was covered and dried out......remove the pins and then dope the remainder of the nylon.

A doped nylon structure is about as strong as you'll get, having flown a lot of the old control line combat wings where it wasn't uncommon for them to be piled in, pulled out muck scraped out restarted and flung back into the air to complete the bout. You could be left with a nylon bag containing a semi destroyed structure that held its shape and was still fly able................mind you I don't miss the three days spent after completing a model picking the dope off your fingers!!!

Final point I've used solar text but for me a nylon and doped finish looks much better.

Ceconite, available from LAS aerospace, Exeter Airport. Does mail order.

We need the lighter version. It's without glue, use a heat activated glue like an equivalent to BalsaLoc. It's not painted, a translucent white fabric, so best used for models which have more than one colour. I have found water based acrylics seals it well.

Very nice to apply, nice shrinking. Finished weight on the plane, painted is similar to Solartex, but cheaper. Way cheaper than Oratex.

For someone versed in silk or nylon finishes, exactly the same, but with precise control over the shrink with temperature on the iron.

When I enquired about Clearcoat they told me that it was only available to callers because of restrictions on posting it.

Back in the days before Solartex and buddy leads (mid-70s) I built a trainer called a Lumpers (I suspect Pete Christy was one of the people who recommended it?) which I covered with nylon. This model survived numerous "incidents" during training with Brian Cooper trying but not always succeeding to snatch the transmitter from my white knuckled hands in time to save it - including the odd vertical terminal dive. The fuselage (and on occasions the trusty Enya .15 engine/silencer - what happened to that white heat resistant Devcon?) just being stuck together with epoxy (cyano was not yet generally available) and the rubber banded wings which would generally fly off from the scene of the crash in a hurry to escape the worst of the carnage just rattled more with each repair of the fuselage...

P.S. Every crash was the result of interference from CB radio.  blush

Covering in Solartex/film was oftetn described as having a built in carrier bag for the bits when you did a whoopsie.
