Just a point of interest when putting and ARC plane togeather. In the instructions it says to use sandpaper and buff the areas to be glued. I go a bit farther and use a hobby knife and SCORE the heck out of the glue areas. I use a crosshatch pattern. It gives a much better glue area and ends up a lot stronger. Of course it takes a bit longer but if they don't come apart in 5 or so years it must be worth it. (and I work them hard ) ENJOY !!! RED
