Speaking of doing on-line searches. A few weeks back I was getting ready to paint my airplane's propeller and was looking for the official standards for painting the tips with markings to make it more visible when rotating. The concern is not giving the Ronco Veg-A-Matic any competition, especially using human beings.
Finding the only FAA standard that referenced the subject to be about 35 years old and long since superceded, I did an online search for propeller markings. Then I Iaughed for 15 min.
One thing that came up was the picture of a 1/32 F3F-3 model I posted on this website years ago. I was careful to mark the model's prop in the three colors used by the USN before WWII, red, yellow, and dark blue. And there was picture I had taken of that model, showing up in a Google search as an example of propeller markings!
I guess I am now an authority, huh?
