Interesting!
About the same density as Aerogel but much, much stronger.
Still a little pricey though..

"Airloy X103 is a lightweight plastics replacement material with excellent thermal insulating and acoustic damping properties. Now available in large panels (30 cm x 30 cm x 0.5 cm)"

($490)

I wonder if it can be molded in a form like our best RTF foam models?

It would be fantadtic if it could be molded right around a brick with built in servos.

That would automatically limit the weight and quantity of the material to the absolute minimum needed so we wouldn't pay for the stuff we cut away in bounding.

With deltang gear we can all fly 1/72nd and maybe even 1:144th sized planes that we can crash into walls and ceilings with reckless abandon..

Here is another one that might be a very usable building material.
It's a foam product made of wood fiber.

A Balsa Foamie ... imagine that conversation at the flying field.

Hello, everybody, I can happily say that styrofoam is a crazy material, because you can build all sorts of hovercraft without fearing a crash, because even if it does crash, you won't have big problems repairing it. This is how it works: http://www.rcfair.com/en/blogs/view_entry/13065/

Good luck

Hello again, here is another little post by a beginner hobbyist sharing his first experience of building his very first RC airplane from XPS (extruded polystyrene) - a kind of insulation, which is used in construction. The guy is too broke to buy materials, so look how he builds a killer aircraft out of whatever he has close at hand. The whole thing was so new to him that he was not even sure that he was actually building an aerobatic type of aircraft... So, read and enjoy:-) http://www.rcfair.com/en/blogs/view_entry/13194/
