Flying tips: Turn it dark

Here is the best solution for those R/C pilot who have visibility problem when flying 'line of sight' (L.O.S) at high altitude on white cloudy sky.  Just paint/spray almost 50-70% your plain plane with black or other darker paint against sky color and you will able to see your plane clearly against the blue,white or dusky sky because your plane wings or other parts looks contrast/visible.  But do not spary the whole plane with same color make sure you make a differentiation of colors on every surface of the plane so you could recognized which parts is up, down, left or right orientation.  Thus you will never loose, confused orientation or lost sight of your plane again.  Cheers.
