I thought the yellow was added by the French,

You have obviously researched the top further than myself, but just remember - it doesn't matter what colour the tip is, it is still yellow, even when it's not.

Betcha didn't know that the "corkscrew" paint on prop spinners that the Germans used here &there was against USAAF regulations...  People would be pulled towards the blades...

My source tells me that the white or yellow "corkscrew" was painted on to keep the paint on the prop spinner from flying off...

This is the RICC effect "Regenerative Inverse Cyclonic Centrifuge" - sometimes abbreviated to BS - but again still yellow!

What keeps the yellow paint on the tips from sliding off?

Sorry, forgot to add that those yellow leading edges seen on RAF aircraft during the Second World War were the same principle. The British pilots were trained to suddenly slam on their airbrakes when a German plane got on their tail. Then the now stationary RAF fighter could fill the over-shooting German plane with lead as it went by. The only problem was the sudden stops were causing the paint to fly off the plane's wings as well. So the yellow non-slip paint was added to the leading edges of wings as well as the props.

The Japanese copied the British but used a lower quality paint. Therefore you see Japanese aircraft in natural metal with some green camo applied. This was caused when the yellow leading edges stopped some of the paint but not all of it leaving a mottled appearance.

The USAAF due to a SNAFU never applied the yellow non-slip paint causing American aircraft to be shipped in olive drab and neutral grey but end up natural metal by the end of the war after all the paint slid off the machines.  

There was a plot to kill Hilter called operation yellow-kyrie. Baron Von Stripperburg was going to remove the yellow propellor paint off Hilter's tri-engine Fokker, thus causing the black paint to slide off, causing the plane to become unstable and crash. Unfortunately the Baron was unsuccessful, because we all know it takes two hands to strip yellow paint.

Several decades ago DHL carried out a study on the costs associated with aircraft painting & discovered that the most effective way to keep their fleet looking good was to paint the whole lot in "slip stop" yellow, as the paints exceptional properties meant that they would most likley never have to paint their aircraft again. Such were the economies of scale that is was financialy beneficial for DHL to paint every single pice of equipment in their inventory in "slip stop".

Apparently the designers picked up the wrong end of the stick on this one, not realising that there creatiuon would not move fast enough to require "slip stop";

When the black propellers were spinning, it rendered them virtually invisible.  Is that why stealth airplanes nowadays are painted black?  Because when they're sitting motionless on the ground, I can see the planes.  But once they start going really fast, they become invisible.  Is that why?

No, everyone knows it's snow cones.

Not sure on that one, but I did hear that the chicken came first!

Ice cream cones come from frozen Canadian cows. Duh!

this must be why some fire trucks are yellow...

No fire trucks are yellow when they have been picked to early, they are not ripe yet.

I thought everyone knows yellow is a non slip color, that is why OSHA requires yellow warnings at  the top of stairs.

lol. now now... Grapefruits, Banana's..grapes, Pears,, are all ripe when there yellow! 

My source also tells me that's why many German fighter aircraft had non-slip gelb wing-tips and noses...

Is that so that when they got shot down, they would get stuck in the air and not crash into the ground?

Eric

It has a very complex structure in comparison to any other colour, which was at one point STS "Super Top Secret" & not very well understood until recently.

I am not competent to even start explaining how it works, but Triarius would likley be able to give a comprehensive description.

Such is the effectivness, they have even made anti-slip shoes from it - the yellow stops the black sole from slipping;

We have a non-slip yellow lab. He's very sure-footed on the wood floor. 

Wonder if there's non-slip for this thread...  It's starting to...

wait wait wait... if this yellow is stop-slip... why do I have such a bugger of a time getting yellow paint to stick to models? Am I buying a cheap knock-off that doesn't have non-slip chemistry. Have I been ripped off? Should I sue?

Yes

Ahhh Scheiße!

That's it, I'm calling the Better Business Bureau, everyone will back me up on this non-slip paint thing right... Right?

No its for when they did crash into the ground the plane stayed together because of the yellow nose and tail.  Saves time and money.  Slap on a new propeller (don't forget the yellow spiral on the cone) and you're good to go.

Most yellows don't exactly match non-slip yellow or non-slip gelb. I hear White Ensign makes a Slightly Tacky Yellow that's really close, though.

Gunze also makes a Mr. Non-Slip Color, but it's almost impossible to find.

Yup!  Right up there with "Buckets of propwash", yards of "flightline", and, boxes of "padeye covers"

Ray

I've had no luck finding propwash by the bucket. All kinds of hogwash though...

You can only get propwash in bucket quantities from industrial suppliers. I found it in 1 liter cans in an auto parts store once, though. Right next to the synthetic blinker fluid.
