First of all, prepare something that you will use during your painting process, like drop cloths, 80-grit sandpaper, clean cloth, sealant, paint brushes, white primer, paint, painter's tape and so forth. Generally, you are advised to paint your model in a well-lighted area. What should you know is that you should paint all sides of the RC model and you should see the plane model from every angle to ensure all angle has been painted.
