This statement is partly incorrect. Metal fatigue is an electrochemical reaction. All chemical reactions are dependent on temperature and energy.

While humidity does not have an effect, storage temperature and direct sunlight exposure may play a role. The higher the storage temperature, or the exposure to direct sunlight, the higher the likelyhood to see an earlier occurrence. Some of us may see it happening before others on the same models either because they contain a higher percentage of impurities or because they have been stored in different conditions.

It is also a fact that storage conditions DO NOT solve the issue, as I already said in my earlier post. To quote Murphy's law, "If a model must get rot for zinc plague, it will" no matter what you do. The worst of it is that it may take years before you realize. So the only option is "check and pray" for your collection and be very careful in buying models which you know are affected.

But please, before being so adamant in your statement and using bold capital letters, do check if you have understood correctly the word of the experts. I don't like to put myself on the high horse, but I am one of those.

tonycutrella

Any pictures to help us understand?

OK Storage May Only Slow Down The Affected Models, But The Fact You Said Storing Your Model Will Not Stop Zinc Rot Proves That There Is Energy And The Right Temperature To Begin With. Displaying Them In Light Might Be A Mild Accelerant, But Displaying Your Model Is NOT The Cause Of Zinc Plague. I Think That's The Point.

BTW I Once Worked In The Marine Industry. An Outboard Motor Casing And Lower Unit Is Usually Made Of Aluminum. All Motors (AFAIK) Have A Sacrificial Zinc Anode Plate To Attract The Corrosion Away From The Motor. The Zinc Plate Corrodes Regardless If The User Is In The Icy Cold Waters Of The Arctic Or The Hot Waters Of Het Yai, Thailand. Not Sure If Temperature Has A Real Effect, But There Is Electrolyisis Regardless Of Temperature.
I Do Know However Salt Water Or Freshwater With High Mineral Content Will Corrode The Zinc Plate Much Faster Than A Motor Used In Non Mineralized Freshwater.

Where are you Andrew?

A Tupolev

Why would Andrew respond, he and his partners in China have your hard earned money in their pockets. We are dealing with unscrupulous people who are only interested in grabbing your money. Do a google search on the Chinese baby milk scandel. If these people are willing to risk the lives of babies to make a profit, why would they care about toy plane collectors. I would pay double of what we are paying now for die-cast planes made in a country with some moral standards.

Herpa is a fine company to be sure but where they lack in good customer service is that they do not produce very many 1:400 scale models. One of the requirements of good customer service is good selection. That Herpa does not have. No one company shines above the rest in the 1:400 scale world. They all have a fault or two. When one considers selection, price, return policy, customer accessability, and usual good quality of product then Gemini Jets would be your best brand, in my opinion.

He is out there trying to find a metal that don't rot and glue that stay's glued

But on the real issue, how can he or others know this was going to happen?

I saw a Dinky shorts Mayo flying boat set, the one with two float planes from the 1930's and they had what you can call metal fatigue! Lack of two complete wings was its minor problem. The major problem was the price, £250.00!

Garuda747400

Why would zinc/metal fatigue affect a dragon wings model when its made of plastic?

I've been banned from posting at 400sh, so it seems all open communications between the collectors and Andrew have been shut down, as the 400sh moderators censor all communications critical of Aeroclassics.

Maybe a list of location of each person would also be good, I wonder what environmental conditions would effect models?

I know some have said it would not, but would be interesting to know where these models are located. I see Taiwan and Florida so far.....

There has to be some common factor here as all of the same model have not been effected and most have release runs less than 400 and were made in the same runs, same zinc, same workers, etc.

I have many of the mentioned effected models and just completed inspecting all my 2002/2003 models and found nothing wrong as others have posted also.

I was actually hoping to find one or two effected so I could inspect them up close and also post my effected models for the nay-sayers but they are all in the same condition as when purchased new.

See, this makes no sense, I have the regular livery UPS 767 and also the UPS 747, both made the same time and both are flawless.

Inspected today.

JustPlaneCrazy

Sorry but.....It's interesting that both these were made in different factories than AC and BB

chen1681

You're right.

As for me, I've collected models for over 10 years. Most of the defective ones were just bought less than 5 years and seldom displayed on my shelf since. These were put in its case/box most of the time and without any sun effects.

Moreover, my rest about 300 models are fine even if some were displyed on the shelf over 2 years or so.

That's why I would say these quality issues were from manufacture's side, not mine.

Will Mr. Diecast watchdog or AK rear end sniffer, why is it you always get perfect product and the rest of the collectors receive crap. Come on till us the truth.

No, I wasn't saying it was a problem with you, it has already been established that it was a manufacture problem in 2002/3003 with the zinc.

What I want to know is why only some are effected when all were made at the same time, same metal, same workers, etc.

The only variable has to be location (in the world) or humidity, or something making the problem surface on some models but not others.

I have no idea, that's why I'm asking......

JustPlaneCrazy

Tupi, I'm done arguing with you as it's apparent you have some mental deficiency and simply want to talk in circles.

I spent several hours inspecting my models as posted above (guess you can't read) and found no problems. I see others in this thread say they did the same and found no problems either, but don't let the facts get in the way of your spin.

SANNY-LAX

Wow, looks like the zinc plague came from the main supplier of the zinc manufacture, so many brand got affected. Maybe just paticular date when the bad quality of zinc was produce and distributed to DW, GJ, AC, HE and others, I have checked all my models and so far only 5 casualties, the rest are ok.

yflchoy

I have all three UPS 767 - Panda Express, Olympics and regular version and only the Panda Express is affected. They are stored in the same condition.

I live in Hong Kong and previously heard that humidity here would affect the models. So from 2006 onwards, all my models are stored in 24-hours air-conditioned and humidity controlled room, but still the problems happen.

Kindly list down the affected models if you may. Thank you.

No, Klink Said "We Discovered The Factory Workers That Admitted They Made A Mistake In A Batch Of Zinc"

With The Feuding Between The Factories, I Wonder If The Other Factories Got A "Deal" On A Few Ingets Of "Pure" Zinc.

pictures speak louder than words. why are people trying to make this an issue for all 400 scale producers when its obviously an Aeroclassics issue. i see no photos of brittleness and cracking other than AC/BB models. the bubbles under the paint issue has been discussed before and has nothing to do with zinc rot. its also interesting that the folks behind SMA have not chimed in on this issue even though they occasionally peruse this forum and are responsible for such models as my rotten klm 737.

L-1011-Heavy

Yes I Read Those Threads Too. The Bubbling Is A Slightly Different Effect, But There Still Had To Be Problems With The Zinc To Cause The Problem.
Because This Happened 2002-2003, I Just Wonder If Another Batch Of Zinc
Had Problems, Or Perhaps They Attempted To Re-Melt The Known Bad Batch, But Still Have Problems In The Form Of Bubbling. Remember Under The Bubbles The Zinc Is Expanding. I've Also Noticed The Bubbling Effect Is Less Common Than The Crumbling Type.

BTW That KLM And All SMA Models Are Aeroclassics Moulds.
Mine Has Crumbled Too.

no, not necessarily, impurities in the paint or factory atmospheric conditions for the bubbles.

Garuda747400

Its not all AC/BB so give todd a break, i have seen cracking on two DW , Aeroflot 777 and DW pokemon 747 thats only the ones i noticed because all my collection are kept in there boxes in a dark room.
Sorry for JAO loss on his BB cathay pacific, thats too nice a model to be loseing, i have all the BB CX and there all fine, i also have a few SMA 737s all unaffected.
Todd does seem to get all models 100% intact with no gear loss, tyres missing, wings detached but maybe he does and doesnt tell.
Have you ever had to fix a ac model Todd?

Guys i know you love the cx model and balkan tu154 but they should go to the bin, there finished

I never said that

I had a few of those DC-10's a few months ago with missing glue, no big deal, about 3 second fix. I just don't go ballistic over silly little things in life, you live longer I've had Dragon and Gemini's also with very minor problems that were fixed in seconds, nothing worth posting a thread over, much better things in life than that.

This thread was about a zinc problem and I posted my findings, you can believe me or not, I don't really care but for those who do, there you go.

There is an easy way for those who don't want to read my (or anyone else's) post is the ignore list.......but that would be too easy for some

None of this is directed at you Garuda....

It seems if you would look back on every thread in the past couple years, it's only a very few people (maybe 4 or 5 out of thousands) that's only agenda is too bash AC, me, 400sh, Andrew or Faheem. They're so predictable it's like fishing.....always catch them

BuddyK

I agree.

I have an old pair of Dragon Wings Phillippines A-340 that had the bubbling paint issue.
I removed (popped & chipped carefully) some of the paint from one of them ...
the underlying zinc showed no sign of decay ...

I was wondering about the layers of paint ... are these things "primed" with something before the outer paint is applied ?

Buddy

Midway1979

I have two of the known AC 737-200s (Pacific Western) and a SMAC KLM 737-200 and I live in the Chicago Suburbs. I haven't inspected about 90% of the collection so there could be more. They have been kept in their boxes in a climate controlled, dark closet for most of the time I have owned them.

I think it is likely that some may take longer to crumble, but I wouldn't be surprised if they all do eventually.

The relaxing part of the zinc plague:

You can't do anything against it!

The lesson I learned:

Don't set your heart on little model aircrafts!


Don’t get me wrong! I still love my models and take care of them but I changed my approach to it. I’m prepared that I might loose them all someday for some reason, maybe zinc plague.

I remember the time when I tried to buy every new release with even a small colorful extra on it since it was a “special livery”. Way too expensive and addictive.

Now I only enjoy buying really colorful jets - from time to time. Saves money and space! If I miss out on one it doesn’t drive me crazy any longer.

Think about this:

19"Do not store up for yourselves treasures on earth, where moth and rust destroy, and where thieves break in and steal. 20But store up for yourselves treasures in heaven, where moth and rust do not destroy, and where thieves do not break in and steal. 21For where your treasure is, there your heart will be also.

Matthew 6:19-21 (New International Version)

Strange? Future will tell!

Unrelated here, but my Phoenix ANA Cargo (Japan Post) '767 from 2007 has had 2 of it's back wheels come off.

I will glue them back on providing it isn't too messy, and the gear is plastic, it just seems a little odd that 2 from the same side of the bogie have come off.


Dang, was thinking about selling it too!

The short version: They're only things, and things can be replaced or lived without. Only life and loved ones are irreplaceable. If having zinc-rotten models breaks your heart, get rid of them and start a new hobby. I have a few in my collection, and I just sigh and sweep them into the trash.
