Is Balsa USA the only source for solartex?
Thanks.

As far as I know, thats it.

If you haven't used it before, you WILL LOVE IT. It is noticably lighter in weight than Coverite fabric (yet just as strong ), does not require the frame to be coated with BalsaRite first (SolarTex adhesive is excellent) and does not require any overlaps to be coated to insure they will stay attached.

One thing I would suggest though. SolarTex has a more open weave. Because of this I would suggest giving the finished product a clear coat of a water base polurethane to seal the weave and make clean up easier.

As far as I know, Balsa USA is the only source in the USA. However, Worldtex, Colortex etc. is the identical product. I also like Solartex (or any of the ***tex's) for the reasons stated above and also am an advocate of the clear sealer over the finished job.

yep. Balsa USA is it!!!

Hey Campy, how do you think it will perform on an uncambered wing? Will it have a tendency to pull from the ribs while shrinking it tight?

I use Solartex on all my Golden Age planes. It looks awesome and it's real easy to apply. Some colors such as Antique are transparent which looks great because the wood grain will show through slightly. Just make sure the wood underneath is clean and free of balsa filler. If you're doing a war bird, the army green is perfect. I spray clear kote over the Solartex to help keep fuel and dirt from staining it.

If the Solartex is going over ribs, it is probably going to pull away.

If you want it to stay with an undercambered wing, you will most likely have to sheet the underside. I did this on one plane. I sheeted the underside with 1/32" balsa and then put the Solartex on - it worked like a charm.

If you go this route, treat it the same way you would when covering a solid balsa surface - start at the center and work toward the edges.
