Actually it is the color of the dye used by the manufacturer (or blender) of the fuel.

I have used fuels that were blue, green, red, purple, and amber. The ingredients used in fuel are all naturally clear or amber. Dies are added to some oils (also a common practice with two stroke oils that are mixed with gasoline).

13x8 apc prop runs a hard 29,627 rpm is it a freek can anyone else compare for me.
Next to imposable numbers.

The OS91Ducted fan engines set up with a tuned pipe turns a 10x9 prop aprox 24,000 rpm when it comes on the pipe and unloads in the air.

Your tach is incorrect.

onethumb was using a shaft-driven tacho so there's more wrong than reflections or lighting.
