Hi...

Why are "Chinese weights" called Chinese weights?!

In Prouty's Helicopter Performance Stability and Control, the author writes that these weights are actually called Chinese weights, for reasons perhaps better left unexplained.

He seems to suggest that the origin of this term is dubious and possibly gruesome. If so, why is it still being used??

Can *someone* please shed some light on the subject?? Any reference or links would be greatly appreciated...

Cheers...

He is talking about chineese weights. you know the weights the chineese use. Not to be confused with japaneese, they get very offended by that.

I asked a girl if she was chineese once, oh, holy mother of mary, and the rest of the gang. I will never do that again.

OMG LMFAO!!!! That was about the rudest thing I've ever heard. I love it

No clue about the question though. Maybe they have a different weight system

Thanks heli_headcase:
There is a screw threaded into the side wall of each (tail rotor blade) grip and maybe 3/4" tall. I recently learned the name of the equivalent part used on the main rotor of some full-scale heli's (Bell 47G for instance) and is known as a "Chinese Weight". Its purpose is to generate a force via centrifugal action to counter the tail blades wanting to go flat-pitch at speed. These screws act as weights to neutralize the flattening tail blade force and give the tail servo a lighter load.

After hearing about what the actor formerly known as Kramer said to a group of African-American hecklers on Saturday, and then hearing about the 6 Muslim imams removed from the US Airways flight here in MSP on Monday, this is the third most offensive thing I've read all week. And it's also been a short, sad week.

It's also the funniest thing I've read in a month, apologies to those offended.

And now to get back on track

I was curious to know what chinese weights are.

Off to trusty Google.
I found a lot of Chinese scroll weights. quite common.
Also, China does have it's own Weights and Measures system

Then I found this article. It references Chinese Weights, Airfoils, and servos. I cant make any sense of it, though. See page 4

http://www.me.wustl.edu/ccm/ahssf2004.pdf

These are Chinese Weights, but used for Diver's equipment

And on another website, specifically mentioning a chinese toy helicopter:
The Helicopter Rotor and the Propeller: China. Fourth Century CE. By the fourth century a common toy in China was the helicopter top, called the 'bamboo dragonfly.' The top was an axis with a cord wound round it, and with blades sticking out from the axis and set at an angle. One pulled the cord, and the top went climbing in the air. Sir George Cayley, the father of modern aeronautics, studied the Chinese helicopter top in 1809. The helicopter top in China led to nothing but amusement and pleasure, but fourteen hundred years later it was to be one of the key elements in the birth of modern aeronautics in the West.
A also found that the Chinese invented a primitive Helicopter in 400 B.C. I can't link that to anything that references Chinese Weights.
that these weights are actually called Chinese weights, for reasons perhaps better left unexplained.
My Theory is The term is made up entirely (and the author could not find any supporting reference)

My research results are inconclusive. Don't say I didnt try.
