Possible? Yes

Feasible? I doubt it.

But the big question I have is - Why?

Even if you could get it to shrink (Which I have no idea how you would do) It would be quite heavy compared to many other coverings.

Id like to ask they same question, why? evan IF you do wont the oil get into the paper and give you this soggy soft goup on your plane?

Sounds like alot of work for not much maybe look into things like silk in dope if you dont want the shine of plasitc coverings..

Is he thinking about brown paper over foam? That's doable.

I remember in the 70's that brown paper was used to cover foam wing cores, but don't remember using it anywhere else...

A friend of mine and myself have both used brown paper covering on complete foam models.Started with a 25 size and finished with a 60 size..had great success with this covering. We used a white PVA glue thinned down 50-50 and brushed on once the paper was on as firm as we could get,when dry it pulled up really tight and was able to paint with car paint. We where amazed at how firm the whole structure was when finished and the weight was about the same as a conventional covered plane of the same size.All up I think we did about 5 planes this way..Just remember dont use heaps of glue,keep it to a minimum.give it a go ,thats what modelling is all about. Our models cost us next to nothing when finished and had just as much fun as the other guys with megga dollar planes.

Thanks for that mintie


Just to confirm are you saying PVA glue shrank the brown paer as it dried



Love trying things out so will give it a go
hate expensive conventional routes

think I will try on a balsa spar and rib wing as well if all goes well

Yes that is correct....get the paper as tight as pos to start with then the glue will do the rest. we used a reasonably thin brown paper. Pic is of a 10. sized seafury with the rear done as I have told you.

Your saying a balsa frame not foam core. brown paper will be heavy but you can dope it liike the old days. silkspan would be much lighter

Lots of the combat guys use blue foam brown paper for both wing and fuz construction. Try ordinary wrapping paper and pva thinned about 50%. It will shrink considerably. After a second coat of thiined pva you need to paint with something fuelproof. As a combat flyer I do not try for a concours finish but some guys get a really good finish with a little rubbing down.

The Spiteful size at 36 in span is great and very light but strong enough for any high speed tight manouvres. The FW TA 152 at 48 in was too high aspect ratio to be easy and I now use glasscloth on the wing but the fuz is still papered.

A true brown paper covering story.....

When I was a kid in the early 60's my grandfather was trying to teach one of my younger brothers to fly control line. He was using an old PDQ Flying Clown powered by an Ohlson .23, covered in this pretty green bamboo paper. Crash after crash broke a lot of props without damaging the airframe other than shredding the bamboo paper to the point where there was nothing left to fly the plane, so "Pop" took it home and covered it with ordinary brown wrapping paper. Put it on damp and doped it just like you would silkspan. I guess it was heavy, but it tightened up fine.
My brother never crashed again! The plane is still hanging in the shop, no prettier after 45 years, but still flyable!

Default RE: Brown paper covering !!

Hey guys i am just about to start cambrian large 1/6 scale Me - 109.
I am thinking of using the brown paper covering technique however there is one thing im unsure about should the paper be wettend with
the PVA 50/50 mix before its applied to the model?.
Also when i bought the model a guy said that if using brown paper it should be ironed aswell ??
has anybody had any experience with this technique??

thanks ....



Happy landings all
