Well, I cruzed through the last posting on this subjuct and I laughed but there were alot of good and bad things to say about the aircore planes, the cloraplast material is available in many of the hobbyshops down here and in sign vendors or old gas station promotional signs. The 1 plane I think as a flying brick would be a battered duraplane, I had known 1 guy who had one and it was affectionality known as the "flying brick" it seemed to wiegh more and more with every crash and the only thing he could do was add bigger motors to compensate for the repair wieght. All in all they're not bad but not perfect either, but then again what plane is perfect, they all have vices to thier design, build or material. I'm more than guilty of changing something because it wasn't the best material or design for the task at hand, so I give aircore the thumbs up for being original in kit production and theory, it sure made people think about alternative materials to build planes out of, heck, if one of the most common production planes uses PCV drain pipe as a fuselage(Duraplane) and still cost 60 bucks, then I give air core credit for using somethin different.
