    Status: offline     		I use my st4500 to weight down stuff while building a plane. it makes a great weight for sheeting foam wings. Some of the tigres were better than others. the st.75 was about the best with the st.90 being the worst. All of them were cheap and worth even less i guess thats why they dont make st's anymore!

    I'll have to tell that to my friend, who has been using his 90 for years with no problems at all.

    By the way, what do you mean by they don't make them anymore?

    Status: offline     		Whoa,....Everyone IS entitled to their own opinion and should voice it, but have some class. If you had a bad experience with an engine then I want to hear about it. I don't need emotionally driven bad remarks blanketing a brand. I don't believe those remarks and I don't think many objective people do. Your experience and professional opinion means a lot more. If some of these statements were true, the product would never have made it to market let alone been around for decades.
    I agree some brands statistically run better/ last longer/ easier to tune, ect. than others, but I'm looking for informed data to help me either get mine running or decide what to get. Slamming a brand without data to back it up does not help me at all.

    Status: offline     		Some people make a lot of noise, and don't say much, I have many engine's 2st. and 4 st. alky and gas, these engines include ST 2500 st 3000 st 4500 my ST's run very well, the 4500 does need A fuel pump to run properly, it is currently on a 27% lanier cap 232 and is no slouch vertical is very good, balance was not a problem, mix my own fuel, alky and oil, about $4.00 per gal.

    I think most Engines just need to be understood, (kinda like women) Some of the stuff I read on these forum's sound's like it is coming from a bunch of kid';s that just like to make noise to be noticed.
    This is just my 2cent's worth.

Of coarse you got to know more than the guy that expects any engine to run right out of the box. Thats a fact.... CaptinJohn

It's on my H9 Edge and it has unlimited vert w/authority. The stock carb had the fat midrange. Thank you for the offer of assistance. Tom D.

    Status: online     		Ray, one thing you need to be careful of with the 4500 is to not let it rev over 8,000 rpm. If you do you're in danger of having the circlips dislodge, I bought a used one to which that had happened and what a mess. I finally gave up and ordered a new Chinese 4500, it will be Dieselized as soon as its broken in. I have many ST carbs I got from people who said they were junk, a simple address change made them work perfectly. The new 4500's aren't here yet so I'm still waiting.

    Status: offline     		Never heard of high rpm dislodging circlips -
    I ran all of my Tigres on lots of oil and nitro and those suckers really run
    You have to carefully loosen em up first tho.
    Favorite fuel?
    15% oil 20% nitro and shimth head up a bit also run exhaust pressure from s muffler /pipe which adds at least 1'4 psi pressure .
    My 2300's ran 9000 on 18x8s (APC) on tuned cans on 20% oil and 30% nitro
    They are very robust engines and as long as you cool em properly you can shim heads and pour in nitro and really make serious power .
    On stingy oil and/or gasoline tho you can wreck em in a heart beat .
    I tried the diesel (?) conversion -once -

    Status: offline     		Remember that when the 4500 was introduced there were very few good gas engines. Quadra had a 35cc and 50cc both heavy by todays standards, as was the Zenoah G38. The G62 was nice but most got a spring starter mount, which added weight. There were also Kiortz and Kawasaki, very heavy. The first high quality, high performance gas engines that I remember were the Sachs 2.6 and 3.7 chainsaw cutouts with C&H ignitions. They were easy to start and blew away everything else at the time. The 4500 is easier to run than a Tartan, they idle nice and perform well up to 15LBs.

    Status: offline     		Hi,
    The G4500 is heavy, but heavy also means = smooth. I have had two of those engines and they both where very smooth. One on a 20LBS airplane and the vertical was unlimited . The other one on a airplane of 25LBS and a tuned pipe. The performance was good but not unlimited. This engine has a very fast throttle response, just like a four stroke engine. The stock quiet muffler, same as for S3000 & G3250, kills this engines performance. Buy or build a good high volume muffler for this engine. Good luck.

    Status: offline     		kaz1104,
    You dont need a fuel pump if you can put the tank close to the carburetor. Just place the fuel tank as close as possible to the carburetor. I dont know about the walbro, but it wouldnt be my first choice for a glow engine. If you are planing to put the fuel tank on the CG then there are other pumps that can be used with the original carburetor. If so do a search on the moki 180-210, or os 160 pump setups. Good luck

    Status: offline     		I am in the process of fitting a Walbro WT225 carb onto a Tigre 3000. The carb has a venturi size of 12.7 mm (.5 in.) and I am using muffler pressure to operate the pump. So far it looks promising. Using a 18X8 Zinger Pro and 5% Omega fuel I am taching it at 8500. I am hoping that I won't have to do anything with the jets. I plan on some more bench runs before I trust it in an airplane.

THEY FLY GREAT-- SOUND GREAT-- AND PILOTS GATHER AROUND MY PLANE AND KUDOS ARE COMMON.. WITH SCALE RETRACTS, RETRACT DOORS ETC, U WILL HAVE A GREAT SPORT PLANE. LOOK AT THE G3 SIMULATOR FOR THE P51 IT IS FLYING WITH A G4500.

    IF ANYONE WOULD LIKE TO SELL ME THEIR BOAT ANCHORS I BE GLAD TO ENTERTAIN ALL OFFERS.

    Status: offline     		You can buy a lot of glow fuel for the difference in price between a gas motor and a new big Supertigre - even more so if you get a used one from someone that is changing to gas. Yeah, the 4500 is a little heavy, but for 90% of the planes out there and the guys flying them, it really doesn't matter. The thing that I really like about the 4500 is that you don't have a huge pump carb sticking out somewhere. It is very compact and makes as much power as a 50 size gas motor (Even more then some). I still build about two planes a year in addition to various arfs that come my way, and I find that I prefer to use the big glow motors in planes that I build myself, and gas motors in the arfs for some reason. I have several of the big Tigres including the 4500 and they run perfectly for years, are easy to start by hand, and never seem to wear out. I don't even bother to use special fuel in them - they just chug along without complaint.

    Tower Hobbies discontinued the ST 3750 about a month ago. The only engines shown above 1.20 cu. in. are the 2300 and 3250. See this link:

    http://www2.towerhobbies.com/cgi-bin/WTI0091P?&C=GCG&V=SUP

    One possible reason is that 37.5 cc engines are in gas/spark ignition territory. Perhaps the 3750 would not compete with the Zenoah G38, ZDZ 40, etc?
