On the down side, they are heavy for their size. There are several other makes of engines that are noticeably lighter in weight for the same size engine that do not require the extensive breakin that Super Tigre engines require. After market mufflers are frequently difficult to find (at a reasonable price).

You may want to take a look at the Evolution and Thunder Tiger engines. They are both in the same price range as an ST, but are lighter and do not require the long breakin.

Status: offline 		I had one about 5 years ago.. Well the ST .45 anyways and I will never buy one again.

I am not extremely experienced when it comes to engines but when I bought it, I mounted and tried firing it up. Well, I spend literally 10's if not 100's of hours trying to get a stable idle. NO LUCK! I took it to the field and the vetrans couldn't get it running properly. The best they could get was a good idle but it would deadstick after 5 mins of flying (with 3/4 of a tank of fuel). Spent 1.5 years putting up with dead sticks. Although I would never buy another ST, I would say that it made me very good at dead stick landings LOL.

Well, after 1.5 years of that junk.. I splurged the extra 30 bucks and got the OS .46 FX and it fired up out of the box with the only thing needing adjustment was the needle.

My opinion (for what it worth!)... Stay away from Super Tiger. But like I said, I'm not an engine expert!

Jim.

Status: offline 		I have had a total of 3 2 st90's and opne st75. The st75 and one 90 from Italy and one of the new 90's. All ran perfect for me. For the price I dont think they can be beat. I bought the 2 italian made ones used but in good shape here in the marketplace for 150 and then the new one from tower on sale for 105. So for 255 I have had a total of 3 75 or 90 engines without a single problem from any of them. Thats a pretty good deal in my book!

Also they run great on 5%. I tried 15% on one of the 90's and it didnt run as well. I had a few deadsticks with it. Switched back to 5% and its back to purring. The ST to me also have a distinct sound.

Are you referring to the ST gurgle when you throttle down in the air? I love that sound!

Status: offline 		Very happy with my STs. The break-in period is long, a gallon or two of fuel, just keep it rich for awhile. They might be a little heavy, but they do seem to last forever.

Ditto, I've had many ST engines from the 45R/C to the 3000.

I've had more 90 K and G engines than any other ST engines and these are great. The 90G is the replacement for the K model and the visual difference is the K model has a removable crank shaft housing.

I've had a couple of great running 90K engines but theres nothing wrong with the G models either.

Status: offline 		Well... It seems as though the verdict is in.

As I mentioned, I am not an engine expert and as a matter of fact I am very inexperienced at engines. I guess a better statement would have been to say that if you lack experience with engines (as I do) then you may want to get an engine that doesn't have as many settings (as HighPlains said) with 3 different needles to adjust.

I do agree that every company produces the odd lemon.

Status: offline 		They don't have 3 needles, just the 2 any other 2 needle carb has.

What they do have extra, is the possibility to rotate the spraybar. It is said to be the solution to part of the rich midrange problem most two strokes suffer from...
I messed with it a couple of times, but I eventually found that I was better off just playing with fuel, plugs and needle settings...

My old S90K is one of my all time favorite engines: it swings a 15x6 quite happily, and it is about as reliable as they come. It needs a new conrod though... anyone know where I can get one...?

Jim,

I wouldnt say that this engine is any more difficult to setup as any other engine. Just be sure to follow the directions that came with the engine and give it a good breakin period. Its not more complicated at all... maybe just a little more time consuming with the break in. Once setup I hardly have to touch the engines... they run like champs. Just err on the side of keeping the engine rich and you will be fine. ALso, as with any engine its always better if someone with more experience helps you out at first.
