YUKONFLYR -> Supertigre..Italian vs China (3/6/2008 12:30:59 AM)

I missed the transition from Italy to China, Bought a new GS45 ABC and it now says China on the back plate [X(]

Is there any difference in the Italy Tigres compared to the China Tigres. I have had them both side by side and they look the same.
Does anyone know if there is a hidden difference?

Thanks

Richard

As far as I know all the tooling went to China. The only difference is the workers, and
the...."Made in China" letters. Maybe someone has some more specifics, but I do know
that the quality is still good. [;)]

FBD. [:D]



YUKONFLYR -> RE: Supertigre..Italian vs China (3/6/2008 12:55:02 AM)

Dave - Thats good to hear...I have read some posts that there are differences....not sure if it is speculation or fact.
Hopefully someone with inside info will chime in.

Lots of folks badmouth the Chinese ones. I have had the italian and chinese STs and notice zero difference in reliabilty or performance.



w8ye -> RE: Supertigre..Italian vs China (3/6/2008 1:36:54 AM)

There has been minor changes made. If any difference, the Chinese versions run smoother through the mid range.



Hobbsy -> RE: Supertigre..Italian vs China (3/6/2008 1:43:52 AM)

My frist purchase after the move was new 4500, but it says made in Italy, then I bought a 2300, fine engine, glitch free carb. Recently I bought a new .51, my old one being from about 1992, the old one was perfect so is the new one and it says China on the backplate.



downunder -> RE: Supertigre..Italian vs China (3/6/2008 2:00:33 AM)

Super Tigre is still owned by the Italians (Garafoli?) who sent their engineers to China to supervise setting up the machinery, training of the operators etc for the simple reason that labour costs back in Italy were going sky high. Any changes to an engine will have been at the least authorised by the Italians.

Hello Yukonflyr:

I'm far from an expert of the subject of engines, however, I own a Chinese Supertigre G90 and G51. I prefer them to my OS 50sx, because the Supertigres are happy on 5% nitro and the 50sx is not happy on low nitro.

My next step to getting my OS 50sx to run the way I want is try fitting a Supertigre carb to it.

I hope that helps.

Bye, Ian

I can't speak for the other engines but I have two Italian made 40's and two Chinese made 40's. Each and every piece will interchange between the different engines and the only difference I have been able to find is a very slight port shape change. They seem to run the same with one small exception. The Italian engines will turn smaller props at higher rpm's than their Chinese counterparts. The difference is noticable with a 9X6 but not a 10X6. As you go smaller with the prop (424 pylon type stuff) the Italian motors respond in kind with more rpm's. The Chinese motors gain rpm's as well, just not as much as the Italian ones. It is my belief that the Chinese ports were designed with a bit more torque in mind and the resulting ability to turn a slightly larger prop for less noise being the goal. Basically it's more of an all around sport flyer type engine now. Hope that didn't add too much confusion.

When did the appocalypse happen?!!!! Making an OS run good by putting a SUPERTIGRE carb on it. Surely, the gravitational pull of the universe has been altered in some way! [:D]

Sorry, had to do that. It just struck me as funny after all the flack that the ST carbs have gotten over forums and to make an OS run better at that! I realize that there is a history but to see people's views change for the better, is a good thing. Of course, now the engines are probably going to cost us more with all the folks buying them up. Get 'em while their hot! And a bargain!

Too much coffee tonight I guess. Sorry, I'll go tinker with a stapler now or something.



ianwynne -> RE: Supertigre..Italian vs China (3/6/2008 3:03:28 AM)

Hello TCrafty:

I was waiting for somebody to respond to my remark.

I will explain why I'm hoping that the ST G51 carb will improve the performance of my OS 50sx.

I want to use 5% nitro in my 50sx. However, with 5% nitro the low speed needle will not lean out sufficiently for a good idle. It's always too rich. If I screw the low speed needle in, if fouls against the carb body, then the throttle barrel will not close properly to shut off the engine.

I'm a "newbie" and it took weeks at the flying field to work out what was happening with my 50sx.

I think that with a G51 carb fitted, I will be able lean out the low speed needle sufficiently.

I have tried using OS #F and OS A3 glow plugs in my 50sx, while the "hotter" plugs did improve the idle, it's still too rich.

In contrast, I've found my Supertigres much easier to tune without endless fiddling with glow plugs and what not.

I hope that make things a little clearer.

Bye, Ian

The R/C engine world has tilted on it's axis [;)]



longdan -> RE: Supertigre..Italian vs China (3/6/2008 3:21:44 AM)

I have noticed the surface finish on the Italian ones is smoother than the chinese ones. Like they have ben blasted with finer beads r something. Not that this will affect performance in any way.



YUKONFLYR -> RE: Supertigre..Italian vs China (3/6/2008 5:25:22 AM)

Thanks Guys,

Its good to know that Supertigre is still making a quality product that is either better or on par with what it was making in Italy[:D]

Richard



rcdude7 -> RE: Supertigre..Italian vs China (3/6/2008 5:59:04 AM)

The best thing is the quality is still there and they are now more inexpensive than ever before. I bought a new italian S-61 ABC engine from tower in the early 90's and it was still around $50 more than today's price. These chinese ST's are an absolute bargain considering the shrinking value of our US dollar today.



stg61abc -> RE: Supertigre..Italian vs China (3/6/2008 8:26:27 PM)

Hi Rich just relax....
Both the Italian and the Chinese ST are GREAT ENGINES.....
They are terrific engines, made to run hard and strong!!!
as ever!!!
Enjoy Your Tigers!!!
cheers



YUKONFLYR -> RE: Supertigre..Italian vs China (3/7/2008 6:53:31 PM)

stg61abc - Its good to hear nothing but good news. I have read elsewhere that the China Tigres were not as good as the Italian ones. The Italian ones do pull a premium on the E site. It is obvious to me now that from all of the good responses that the China ones still have Italian blood in them and will run just like their former brothers.

Bring on the China Tigers[:D][:D]

50+AirYears -> RE: Supertigre..Italian vs China (3/9/2008 3:07:39 AM)

Last year I fired up my first ST engine. Had a Chinese ST .45 in a Goldberg Skylark. Got a chance to compare it to a 25 year old Fox .45
On APC 10-6, about 200 more rpm on 10% nitro. Also minimum idle was about 400 higher. Throttle response was slightly smoother. About the 10th run, just before releasing for maiden flight, engine started running sour. Throttle retainer had loosened up. On second flight, started running sour again. Luckily, I saw where the loose head bolt flew to. Had to tighten all of them.



MetallicaJunkie -> RE: Supertigre..Italian vs China (3/9/2008 10:19:26 AM)

back in the day (late 80's early 90's) super tigre was(my choice) the economical alternative to O.S. engines(especially tune piped)..... and still today.........their only flaw in my opinion was the way the stock exhaust was set up....... as far as i remember all my ST's were made in Italy.....Sorry to hear that the ones made in china are flawed

I guess my two Chinese Tigres don't know that they are!!! [:D]



Jezmo -> RE: Supertigre..Italian vs China (3/9/2008 3:06:12 PM)

On the issue of loose parts, I have had loose parts at some point on just about every engine I have ever owned. I consider it "routine maintenance" to go over them and tighten things once in a while. (Starting with when they are new) Since I fly choppers and tighten EVERTHING on them before each day of flying, I have just made it a habit to do that on all my planes as well. It's just good practice to check things over from time to time.



Flyboy Dave -> RE: Supertigre..Italian vs China (3/10/2008 12:20:34 AM)

.....let's not start any false Internet rumors, shall we ? [:@]

Chinese Super Tiger engines are not "flawed" in any way !!!

FBD. [:D]



MetallicaJunkie -> RE: Supertigre..Italian vs China (3/10/2008 2:33:46 PM)

actually i have one that i purchased 3 years ago(st 90), not sure where it is made though, its in a tight cowl, but runs great



w8ye -> RE: Supertigre..Italian vs China (3/10/2008 2:49:50 PM)

Some Super Tigers are of doubtful origin. The first ones from China still said made in Italy on them. It was probably a year after that before they started saying made in China on all the parts.

I agree FBD. Like I said in post 9 above all of mine run great and the SuperTigre's at our field don't have any more problems than any other brand. I've helped a few guys learn to adjust the MAG carb and afterwards they love em.
