    RE: What's a SuperTigre G-4500 good for?

    I FLY THE ST 4500 ON MY TOPFLITE P51D AND THEY WERE MADE FOR EACH OTHER. I SUGGEST THAT YOU USE THE PLANE AND ENGINE YOU HAVE. 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.

    RE: What's a SuperTigre G-4500 good for?

    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.

    A Walbro WT499 from a glow G23 will work very well...Use crank pressure, I don't think the hot exhaust from the muffler will be good for the diaphragm...

    For everybody's information, Tower Hobbies discontinued the ST 4500 some time ago.

    RE: Tigres

    I think *SuperTigre* discontinued the G4500 some time ago -- leaving Tower with little option but to do the same :-)

    RE: Tigres

    The Super tiger was about to release a new 37,5cc engine 2.25cu.in. to replace the G4500. Would like too see when it will hit the market.

    RE: Tigres

    Flyer95,

    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...P?&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?

    cu.in.
    Are you sure they have discontinued the ST 3750? There can be many other reasons why it is not shown on the Tower list.

    RE: Tigres

    Flyer95,

    I was going to order one this spring back when Tower showed an "Order Pending" stock status on the link (above 1.20 cu. in.) I posted before. At that time, there were three engines shown, the 2300, 3250, and the 3750. There was no picture of the 3750 engine on the link. I didn't place an order because I wanted to see what the engine looked like.

    It seemed like six months passed by with this "Order Pending" status shown, and then about a month or so ago, the 3750 "Order Pending" image disappeared altogether, leaving us with the current "above 1.20 cu. in." link that offers the 2300 and 3250 engines only. This is all I know for sure.

    RE: What's a SuperTigre G-4500 good for?

    The Super Tigre G4500 makes a great doorstop. No, I'm not kidding.

    Why anyone would run anything other than a gas/petrol engine in this size is beyond my understanding. Apparently, those that own the design/rights to this engine feel the same way, since they stopped offering it for sale.

    Do yourself a favor, put it up for sale and buy something like a DA-50, Cunningham G62 Lite or a Brillelli 46 or 60.

    And no, converting the G4500 to gas/petrol is not worth the effort.

    Sometimes folks make mistakes. The G4500 is one of them, as are the G2500 on up engines.

    I'm just trying to save you heart break, frustration and the spending of lots of needless money and time. Large glow engines are born problematic and inefficient.

    This is just my opinion and is not intended to offend.

    RE: What's a SuperTigre G-4500 good for?

    Well, I can get an ST4500 for a hundred bucks and my Futaba gold box AM radio doesn't like ANY RF interference. I agree, I can't see why anyone spending over $1000 on a fragile toy would buy an ST4500.

    RE: Tigres

    I wouldn't mind a G4500 for $100.

    Hell, down here, methanol is not much more expensive (sometimes even cheaper) than gasoline and these big engines don't need as much oil as regular glow engines.

    Even though they do drink more than twice as much (per minute) you're saving the weight of a CDI and battery so that extra fuel isn't too much of a payload.

    Anyone got a good one they want to sell?

    -----------------


    I used to test pilot giant scale models for some pilots in our club, back in the very early Eighties. All these folks had for radios were AM Futaba radios. When things were hooked up right, the Futaba AM rigs were just fine. The same things that bothered AM radios also bothered FM radios when they came along. Besides, using the term AM and FM to describe a model R/C system is a joke. They are neither. At least, not in the USA.

    I'd give someone $100 for a good looking ST G4500. I wouldn't ever think of flying it, but I would buy one.

    There is nothing wrong in using this engine. It makes lots of power and have very good fuel economy if you run it on the recommended fuel which is 10% oil and methanol for the balance.
    Mine could easily turn a MenzS 24x10 or Forte 22x12 @ 6300rpm.

    I agree with you. There is nothing wrong with using the G4500. That is what a hobby is all about - doing it your way.

    I'm spoiled with the gas/petrol engines using Walbro or Walbro type carbs that do not care about fuel tank placement. I'm spoiled by the extraordinarily low cost of fuel for said engines.

    I currently own a couple of glow engines that are over my normal 1.20 size limit for glow. I'll probably use them at some point, just for the heck of it, and then just as quickly replace them with gas burners for lower operating costs. I can afford glow fuel, but it is a quirk about my personality that drives me to use the least expensive fuel available that works well. Still, upon occasion, it is fun to "power up" the small sized gas planes with a brief usage of a strong glow engine.

    I'm not against glow engines in the larger sizes. It is just that gas does the job well for me in those sizes. Besides, I hate cleaning the glow goop off of my model. But that's me. You and everyone else may see it differently.

    RE: Tigres

    If you guys don't like the 4500, send me a PM with what you have, and how much you want for it. I'm in the market. I don't need vertical performance, I like to fly within the scale envelope, and the short nose, long tail models that I fly use the ST 4500 very well.

    Its easy, just glue all the pieces together, and sand off everything that doesnt look like an airplane.
