I did a reserch on this subject before painting our RV9a.
Here is an extract from a post on another forum on our reasoning for our paint choice. And a photo is in this thread on this site (scroll down the page a bit) http://www.recreationalflying.com/threads/rv9a-registered-raa.26984/
To come up with a paint job for our 9a (now called "Slipstream Runner") has been a continuing headache. For you guy's that have done this before, you'll know what I mean. You keep changing designs, colors etc etc.
Color; After tossing around various colors, I decided to go with safety, something that could "be seen". So I got onto the forums and did a research on the best to be seen colors. Some say a dark color is the best to be seen, "you can always see a black a/c". While another stated "we have a bright yellow a/c in our club, and you can always see it in the circuit". While some others agreed a polished aluminium a/c glints in the sun like a mirror flashing at you.
So I went with all three. Bright yellow, a dark metallic gray (looks like black from some angles and brown from other angles and only with the reflection of the sun does it look like metallic grey). And polished aluminium. And Robyn did her usual thing and did some nice graphics with some signwriting and put them on.
The design; Ok, The idea of the design was #1, Keep the weight down. #2 Because most of the weight saving in the aircraft to register it RAA, was under the cowl and in the cab. Looking after the C of G I wanted paint up the front and in the natural area (wings etc) and very little (if any) on the tail. Ok I had to put some on the tail for a visual balance. But there is none on the elevators and only the minimum elsewhere.
