Status: offline 		Hi.... i have been flying mostly foamies and i wanted to make a new wing for one of my planes, i am wondering if there is a plastic type coating, similar to monocoat or ultracoat that can be put on foam? Anything that wound stick to foam and give it a tougher finish. Even a clear coat type paint...anything really.

Just wondering.

Thanks

You can use plastic films, as long as they are of the low heat variety. Some people put lightweight glassfiber cloth on their foamies with, what's it called, Water Based PolyUrethane). I've heard that some combat guys use pantyhose (nylon) instead of glass.

Whatever you use, you need a smooth surface under it.

Status: offline 		Thanks for the help...i was looking for something in a peel-n-stick solution. The fibreglassing is nice idea but would it crack if it's too thin? and if it is thicker would it add too much weight? Remember this is a foamie parkflyer with a cheap brushed motor.

Thanks for all the help.

Status: offline 		Packing tape adds strength and durability. It will shrink with heat to get around compound curves. If you have trouble with it sticking, spray the foam with some adhesive first. Be sure to use Elmer's spray adhesive - it's the only one I've found that is foam safe.

Status: offline 		If you can find it...some stuff called Fascal 700 made by Fason corp (they were bought and are a division of Avery now). Clear peels off of a paper backing with a very sticky adhesive on it. Fascal 1200 is the same material with a less aggressive adhesive that is just kinda tacky.

With high heat, both shrink like crazy, but over foam you won't need to shrink it.

Fascal is much stronger than Monocote and significantly cheap...if you can find it.

Status: offline 		Back in the day I had a small 15 sized trainer, can`t remember what it was, but I`m pretty sure it was Sig, anyway it had a foam wing which I just covered with I believe Monocoat or possibly econo coat, not sure if they make that anymore, more than likely it was econo coat as I didn`t have much money back then. It worked great and strengthend the wing unbelivably! I crashed that plane many times, even had to build a whole new fuse from scratch, but never damaged that wing.Hope that helps, just don`t keep the iron in one place too long, keep it moving. I don`t remember melting the foam at all.

Top flight econocote, Solar film And Black Beron are all low temperature films and work on foam. And H-9 ultracote made a contact type of covering.
