Here is a three part series on adding MonoKote Trimming. This is how you can add a trim bar to the underside of just about any wing. The plane I am using here is the Viper 500 From Great Planes. This technique can be used on any type of film covered plane and having easy to see graphics in your plane will make it easier for you to see and keep flight orientation.
