i think ive decided on colors, Light Yellow (cub Yellow) against a dark green (British racing green

)
now going back to the previous comments (cant quite remember who said it) im planning to put yellow stripes down the side and along the wings so you can see the planes attitude in the sky (if you see the yellow lines pointing up in the sky, you will know you are going vertical! with orange wingtips, a black canopy/windsheild BUT... i will put little Yellow or orange stripes across the leading edge to show the attitude of the wings and it can easily be seen against the trees when im coming onto approach for landing
essentially the patternwork on the Stuntplane from GTA: San Andreas (some of you elders may not know what im talking about :P)
