Ditto, Contrasting colors of dark and light are far more important than the colors themselves. Medium shade colors can all blurr together.

Also, definitely work on keeping the plane closer. I am always amazed when i see people flying WAY far away or WAY up high. I usually ask them if they don't like the way the plane looks. That's the only reason I can think of as to why they fly where they can't see the plane.

Bring it IN! Keep it close!
