Finally, I will apreciate your help, and I'd like to say I live in a third world country, so much of your stuff is not here,... yet. Microballoons are very tiny little glass spheres that you mix with epoxy to get a more paste-like epoxy mix. They are used as gap-filler, for making fillets and to lighten a given amount of epoxy that would be applied (sometimes used for park flyers or indoor flyers). I don't know how you would order them, but Tower Hobbies http://www.towerhobbies.com has several different brands of microballons. RCSE-List facilities provided by Model Airplane News.

RE: [RCSE] micro balloons
Micro balloons are spherically shaped silica hollow 'beads' that are so small they appear as simply white powder. Because they are hollow, they are very light. They are used as a lightweight filler for epoxy, to make a paste for creating fillets or other epoxy 'fill' applications. The resultant mixture of epoxy and microballoons is not considered particuarly strong, but may serve more than adequately for some structural needs. There are many other useful fillers for expoxy, depending on the desired strength, flexibility, color, and weight of the resulting mixture. Some of these include finely chopped carbon fiber, finely chopped cotton fiber, wood flour (very fine wood dust), etc. There are even fillers where each particle is a little flat 'plate' shape. The ability to mix literally different shapes of micro-fill into epoxy is one of the things that makes composite construction aspire to idealized structure at the microscopic level. Creating different epoxy 'butters' with combinations of these fillers tailored to specific structural needs is part of being a skilled builder in composites.
