Creating backup parts.. http://www.gmfoam.com ??


Hi,

I'm trying to create copies of wing/fuselage of a plane so that I have backup parts..
I checked out http://www.gmfoam.com where they sell foam kit that can be whipped in a mixer, filled into molds, and cured in a low temperature oven. I'm not sure about their price and the hardness of the foam though.

However, could u please help me to create foam copies of my airplane ?

Big Thanks.

Jake.

I would think casting foam would weigh too much. Its just not designed for wings and fuselages on airplanes.

Foamed latex (rubber)


Jake,

Looking at GMFoam's site I see that their product is latex that is used by make-up artists in the movie industry.

This is a rubber product, rather than the foam that is used for r/c aircraft wings and fuselages.

I still don't have an answer to your question, but I am pretty confident (despite my limited knowledge in the r/c hobby) that GMFoam is not what you are looking for.

Ditto what Mike says. The two-part foams are used for insulation and/or floatation and weigh more than the foams used for planes. Could be wrong, so Email this company and ask them what their foam weighs per cubic ft and then compare to other rigid foams.

Thanks very much for the input.
GE Foam may not be good idea, but what I'm trying to
find out is to have a foam in liquid or power so that I can
make copies of the fuselage and wings.
MAY BE it could be too much work for end users.

I've got this idea when I went to Home Depot and saw a
foam sealant in a spray can. It's elastic and very sturdy.
I imagined a large amount of these to pour into a fuselage/wing frame to make multiple copies.
Frames can be made out of original fuselage/wing.
Is this crazy ? or is there a way ?

Thanks !
Jake.

Jake,
I've used the two-part liquid foam in a number of applications, (usually floatation chambers in small boats) and it works great! But only in boats. Too heavy for E powered planes. It would be nice though. Only the big manufacturers with expensive equipment can do the light foam parts from liquid. Ever notice that you can buy spare fus and wings for the GWS planes? They know that we can't produce them ourselves and so are more than happy to sell 'em to us!
