poly-span

hi folks!
do flyers still use poly-span? i don't hear much talk of it lately. is it still a good product to use?

Yes, still using it. Much stronger that silkspan. I also use Thermal Span which is a similar type of product. When I run out of current stock I plan to try dress liner material which several have reported here that it works just like polyspan, but much cheaper and locally available.

I use poly-span but I hear it is no longer available. As far as using dress lining I have also used that in the past on R/C planes but by the time you seal it up with dope it can be heavy. Does anybody have a current source for poly-span or a similar product.

Poly Tissue (formerly known as Poly-Span) is available from Jim Snelson at CLCentral.

You can get polyspan in lengths that will carry you farther then the old starlite offerings.

I have just finished covering my version of Leo Mehl's Arctic Fox with Poly Tissue. That is what Tom Morris calls it. It is still Poly-Span. I have followed Tom's directions pretty much.

I have discovered that on the solid areas in which there was a ripple or the covering bulged up I could hit it with the trim iron and shrink it down. Also as far as telling the difference on which side goes down, put the material down on a flat surface. It will bulge up if the smooth side is up. If the rough side is up it will curl up at the edges. Or sight it real close and you can see the difference in texture. If you mess up just do like Tom says, "Use more clear dope". Same when you get too aggresive with the sanding.

By the way I am using Brodak Clear thinned Half dope, half thinner.
