This review only discusses the building process for the Great Planes Extra 300sp (50 inch wing span) electric ARF. During the build I encounter several issues. The first problem occurred trying to install the landing gear, which fits into the airframes body. None of the holes lined up with the preinstalled blind nuts. I had to elongate the holes in the landing gear to fit. Several pieces of the hardware were the wrong size for the tail wheel assembly. I had to use hardware that I had on hand to install the tail wheel properly. Some to the 2-56 nuts used on the pull-pull rudder systems also were not properly machined and did not fit. As large as this plane is it was difficult to access certain other areas during the build. I have always believed Great Planes was top notch equipment. However this plane is differently not a beginner build even thought it is an ARF. I have worked through all of the issues and am now anxious to see how well it fly's.
