I for one would love to have an RC all aluminum scale GA type aircraft, Its still on my to do list. I believe that the reason why you don't have many out there is that, people do not have the knowledge on how to build one, way different then cutting and gluing balsa. Also the myths that they are too heavy, wont fly, can get good signal out of one, to dangerous... bla bla bla bla bla. In this gotta have in now world that we live in, its hard enough to have guys in the hobby that will build a stick kit anymore let alone an exotic metal plane. I say if you truely have an interest in having one, do it! Don't let the nay sayers that don't have the understanding and ambition on how to build aluminum planes keep you from it. Its been proven that it can be done!
