I added elevon extensions to my Charlie and tested it with a noticeable improvement on handling. I also worked more on the 1939 Popular Aviation Special hand drawn plans. I have five tiles done that include the tail plane, vertical stabilizer, wings, and extra fuselage pieces. All that's left is the main fuselage, which will take three more tiles. After that, I need to draw the detail marks like indicators for the type of cuts and folds to use and then figure out how to scan and submit.
