The tinted canopy I was looking at was the same red heli you were referring to...It seems to have a "purple tint" to it like that new Ford mustang thats painted "chameleon mistic" and changes from Purple to /Green depending on the light and angle....

I am a auto-body repairman/painter for a living, and just happen to have access to one of THE best automotive paint systems ever:
SIKKENS! My friend owns the auto-body shop, and does mostly late model, high end, collision damaged cars/motorcycles. He installed the SIKKENS system after using PPG for many years.

I just purchased a Kyosho 46VR that I am going to base/clear with automotive Sikkens, (not sure yet on colors/graphics), I am going to shoot the "chameleon" ($250.00 A PINT!!!!) on the inside of the canopy. Rather than the Ford "mistic" I am going to use a 8 COLOR CHAMELEON! the Ford only changes 2 colors!
