I am 63 years old and have not been active in this hobby for over 30 years except for flying an electric park flyer recently. I have aquired a 40, four channel, trainer kit. I would like your recommendations on the best color combinations on my plane when I cover it so that I can easily see it's orintation at higher altitudes. Example; Would black on the underside and orange on it's top be good so that I will see if it's banking left or right be better? Thanks.
