AJF--2 -> Why isn't the SuperTigre 2300 a popular engine?? (12/9/2005 3:18:39 PM)

I have been in RC for quite a while, and in Giant Scale (with gas engines) for the last few years. I have owned a number of SuperTigre glow engines (in the 40-90 range) and have picked up this 2300 recently. It seems that Moki, OS, and Webra get the most discussion. Also planes in the classifieds with this engine are priced lower.

I know it is a ringed engine and will probably not produce stunning power. But what is the problem that they are not as popular? Thanks in advance-- all comments welcome! (not going to get mad if you talk bad about my engine)[;)]

The ST 2300 is a 140. It was brought out to use in pattern back when that was the max allowable size in pattern.

Shortly after it came out, Super Tiger closed thier doors and for about 3 years, you couldn't buy Super Tigers.

Only recently have you been able to buy a 2300.

Shortly after the 2300 came out, there was the Y-S 140 four stroke and since the 160.

The Moki's are 210's, the OS's are 160's.

There are other, even bigger, Super Tigers like the 3250 and the 4500. They were not available either. Years ago they made a 2000, 2500, & 3000 but these engines are no longer in production.

Super Tiger lost a lot of market share in their move to China.

Enjoy,

Jim

"Super Tiger lost a lot of market share in their move to China."

Darn shame that isn't true across the board! There wouldn't be that huge sucking sound from over Kahina way.

I think the reason why the big cats aren't popular is because of the carbs.

I've owned my share of the cats--back before I switched to gas for big planes--and I always had carb problems. I ended up buying a bunch of OS7D carbs for the engines. Thats fixes the problem--but at $70 apiece--it's kinda BS. I was buying ST engines because of the price--but then you add another $70 for a decent carb--and they aren't so cheap anymore.

They do make power though. I was pretty impressed with the ST3000 pulling a 20-6 or a 20-8 prop at 7300RPM on 5% fuel at 6000' elevation. The 4500 was cranking a 22-10 at 7100RPM--but good GAWD, that was a thirsty beast!! I sold it pretty quick.

Supertigres 2300 is one of their finest engines since they have fixed the carb design of the early production models. You will have to spend a few minutes getting the low needle set. The cause of many problems that I see are from people using too large a tank mounted too far away, too large a prop, and sometimes too much nitro. These same people are also the most vocal about their sorry Supertigres. The 2300s large carb is sensitive to tank location and needs good muffler pressure, 9000rpm+, and around 10%nitro. [I use 5% coolpower] A 16oz tank will run over 10 min with a small mixture change as the tank empties. Popular or not its a very good engine at a bargain price.

Additionally, before Super Tigre closed its doors, they stopped making the carb barrel with the proper groove machined in it for the G2300's needs. They substituted the barrel for the 4500, which had a different groove. The groove configuration affects the midrange mixture. Suddenly, what was a well behaved and excellent running engine turned into a nearly unusable paperweight.

Mr. Reivers, of this group, has done extensive experimenting and posting on this group detailiing how to machine the proper groove into the barrel with a simple Moto Tool and a cut-off wheel.

Hopefully, the newer Chinese versions have been restored to the proper groove configuration machined in the carb barrel. End of problem.

How much faith do I have in these engines? I just bought a new one a while back. They are fantastic engines and they come embarrassingly close in power to the OS 1.60 FX at over $100 less expense.

I'll tell ya I have a very old Italian, one of the originals, and avery new Chinese and they're both real popular with me. The only thing I had to do with either one to get them to run right was put fuel in the tank and start them up.

I bought a new 2300 this past summer and I have nothing but good things to say about it. There was no carb problems and with my Perry pump the gas tank location is not an issue. I think that these engines will become popular again as they are very price competitive.



flyathome -> RE: Why isn't the SuperTigre 2300 a popular engine?? (12/10/2005 4:46:05 AM)

I have a 2300 that I bought in January of 1999. It has been in several planes. I made the mods to the carb. I think I got the information from Dick Hanson. With that change my engine has been very reliable and powerful. One other thing I did that seemed to help was to run an OS F glow plug. Right now I am buiding a new plane to put it in.

I have 2 2300's. I really like them. I have used them with original carb, and with the Perry# 5001. It's a great engine for my 25% Edge. I use it with a DH Models(Dick Hanson) tuned muffler with a OS 'F' plug and a APC 17 x 8 or 17 x 8n prop. The best power comes from the Perry carb and the DH muffler( for uplines and sequences),but it flies very well with the stock carb and a pitts muffler. I really like the engine.

I have a G2300. It's by far the highest power-to-dollar thing you can get anywhere, except for maybe MDS 2.14. It can swing APC 18x6W @ 8500 rpm with a BCM Pitts muffler. I am sure it can do more with stock muffler, ever more so with Turbo Jett muffler.

There is nothing wrong with the new Chinese version, except if you try to use an after-market scale muffler without pump or re-equating its back pressure to that of the stock muffler.



rc34074 -> RE: Why isn't the SuperTigre 2300 a popular engine?? (12/10/2005 1:10:45 PM)

My chinese 2300 runs very well. when i broke it in i never needed to adjust the low end needle- it ran great at idle out of the box. i run omega 10% and after breakin it turns an apc 16-8 prop about 9000-9100 rpm, which is the same rpm as a saito 150 turns that prop (at least that's what the horizon site says the 150 does).

if you change the muffler you need to make sure that you have the correct back pressure for good fuel flow to the engine. i tried a slimline pitts muffler but it has outlet tubes that are much larger than the stock muffler tube. so i squeezed them down with a pair of adjustable pliers to about the same area as the stock muffler tube. then the 2300 ran great- it has very even carb/fuel flow and runs very smoothly at all rpm.

i put mine in a top flite 60 size p-47 - this plane flies GREAT! with this engine. i bought a second 2300 for a 120 size mustang.

I have my 2300 set up for speed in a Modified (Dago Red) style P51. Its inverted with a Jettstream muffler and a 14/14 apc. Flying it almost a year now and performs up to my expectations.

Actually, your G2300 is considerably stronger than a Saito 1.50. A 16x8 prop on the G2300 is under propping it. Try a 17x8 or 18x8. You will be surprised.



Sturtz -> RE: Why isn't the SuperTigre 2300 a popular engine?? (12/13/2005 6:46:53 AM)

I bought the 2300 a few weeks ago for a 1/4 Edge540T. I tried the Perry routines with little results and went back to 100% stock including muffler. Luckily I live in the same town as Bob Pastorello and he helped me get it adjusted correctly. I learned alot from Bob about the big cats and other 2C engines. Needless to say he saved the motor from a quick sale or sledge hammering by me.
Now it runs great and I'm looking forward to running some more fuel through it to see if what everyone says is true about these motors.
"As you near the 4 gallon mark or so the engine really starts to smooth out and power up . Plus it becomes much more reliable."



chuck993 -> RE: Why isn't the SuperTigre 2300 a popular engine?? (10/5/2007 5:18:09 PM)

I have one and two carbs froze on it, one after the other, I subsituted an OS carb, works great now, the carbs are crap.



Not24 -> RE: Why isn't the SuperTigre 2300 a popular engine?? (10/6/2007 12:05:52 AM)

I love mine with a 16-10 and an unmodified Slimline muffler, Magnum 1.08 carb and 15% Omega. It turns this prop at 9000 plus. The 16-8 turns 9500. That's what the Saito 1.80 turns that prop, so it's got plenty of power, especially for the price.



djlyon -> RE: Why isn't the SuperTigre 2300 a popular engine?? (10/6/2007 12:23:02 AM)

I love both my Italian and Chinese 2300s. They've both flown the Balsa Nova you see in my Avatar. Mine work great both completely stock. muffler, carb and every thing else. APC 17/10N at 8000. Probably more if I squeezed it.

mabey i don't know what i'm getting into , but as an interduction to giant scale, i'm going to install a 4500 in a bridi big bee, i'm betting i'll like it.

Yes the 4500 had a carb that was about 12% over what it needed. As you run it, it pours unburnt fuel out it's exhaust. Try reducing the barrell opening a little bit and readjust and see if it helps you.

Hope you got room for a at least a 32oz tank. That 4500 will gulp down a quart in about 8-10 minutes, and you better hit the landing on the first approach-- 'cause you ain't got enough fuel to go around. [:D]

They do run good, but I just couldn't justify the sucking sound in my wallet. At this size--gas is a whole lot cheaper. The glow engine looks attractive up front. It's cheap to buy. But it goes through fuel like a drunken sailor goes through cash at a casino. After about 5 or 8 gallons of glow fuel--you will have reached the break even point on a gasser. Everything beyond that, and you're loosing money buying glow fuel when you could be buying gas at 1/5 the price.

They do sound good and put out ridiculous power though. Might be okay for a big Mustang that you only plan to fly once or twice a year at the big fly-in. But I couldn't justify it for a sport plane that I wanted to fly every weekend.



Hobbsy -> RE: Why isn't the SuperTigre 2300 a popular engine?? (1/11/2008 1:04:23 AM)

Same here and the carb barrel is smaller than the 4500 barrel.



TCrafty -> RE: Why isn't the SuperTigre 2300 a popular engine?? (1/11/2008 2:01:37 AM)

I've got two 2300s. One is in a Goldberg Sukhoi and I love it. Bisson Pitts muffler, stock carb, running 15 percent nitro. Didn't have to close up any exhaust ports, so far, never a dead stick. ( I might have just cursed myself) [:D]

the second one is in a Pitts that my dad is scratch building for me. it used to be in the Suk but I figured I'd break in a new engine on the Suk instead of a pitts so I pulled the 2300 from the Suk and bought another 2300. I don't know why they haven't picked up more but, I want to buy a few more before the demand goes up!



boex -> RE: Why isn't the SuperTigre 2300 a popular engine?? (1/11/2008 4:22:51 AM)

My 2300 changed from running like a poorly made Fiat to a Ferrari by simply replacing the plug to an OS F and installing a VP-30 perry pump.
