The way an engine , any engine is broken in will determin it's power output AND life span.

This is especially true with ABC engines as opposed to "ringed" engines.

Gas engines like Zenoah and the more expensive BME take a very long time to brake in.

Thanks for the explanation on the baffle.

I do have a question for all the ST fans in here. It seems as though everyone is saying that they are the best engines made. However, the one common remark is that they are very reliable "after the long break in". Why would someone want to buy an engine which is more work to setup and configure the right settings and unreliable during this process? I mean, after all using an unreliable engine during the break in is definitely increasing risk as you increase your chances of a dead stick.

Why wouldn't someone just go with something like an OS which seems to be a more "out of the box and go" type of engine? I even had a thunder tiger as my first engine at that thing ran great (until it took a nose dive into a local farmers field).

Just curious?!


The engines are very reliable during break in as well you just have to take your time and keep it rich. And the break in is not all that long. For a ringed engine I generally run it close to an hour before taking it up then I finish the break in in the air. Its not really that much work. Like someone already posted if you take care of it your ST will run forever. Ringed engines are none for their longevity.

The reason I would buy a ST 90 rather than an OS is that it cost $120 NIB as oppossed to $200 for an OS 90. That $80 or so dollars is worth a little extra break in time to me. I dont have anything against an OS 90 and know they are great engines but if I can save $80 and still get a good engine I am going to do. If Thunder Tiger made a 90 I would be first in line to buy one. In fact all the engines I have are either Magnum, ST, or TT. All economy engines. I just cant bring myself to pay premium dollar for OS, Saito, etc. Sure those are some great engines with great features but for me I am perfectly happy with my more economical engines on cheap low nitro fuel! Its all about stretching those hobby dollars!

Status: offline 		Agreed. ST engines come from the factory with the low end set rich. Transition isn't very smooth at that setting, and you can't really change it until the engine's broken in, because a new engine won't hold a good idle at a leaner setting. For this reason, trying to smooth the transition on a new ST can be frustrating, leading some to think the engine is finicky. However, after the first gallon of fuel, you can start leaning out the low end 1/8 turn at a time, and you'll soon have a strong, reliable engine.

Status: offline 		When you say run a gallon of fuel through the engine to break it in or run it for an hour before taking it up. Are you talking full throttle? Half throttle? All in one shot, or do you run it 10 mins. at a time?

I only ST I owned was the .45... It was only $30 difference between that and the OS. I went with the ST and I thought I had broken it is but I guess I didn't. I ran quite a few tanks before the first take off. I was told to run it rich but when I did that it wasnt very responsive to the throttle changes. Then it would start to lean out and eventually dead stick when it got to about 1/2 a tank of gas.

Did I do it wrong?

Status: offline 		Super Tigre engines are to be broken in before any flight time. They are broken in at a rich FULL throttle, after 10 minutes, pinch the intake line for a second and release it. If you hear the rpm and pitch go up on your engine, you can lean it out 1\8 -1\4 turn. Run again at FULL throttle for another 10 minutes, and pinch the line again, if you get the same results, lean it out another 1\8-1\4 turn and run for another 10 minutes at FULL throttle. Keep doing this until the engine does not lean out or increase rpm when you pinch the line. Your engine is now ready for flight, but open the high speed needle back out at least 1\8 - 1\4 turn from your setting for several flights. Basically, fly your plane as rich as it can fly at first, and slowly lean it out flight after flight....... Greg

Is this the process that should be taken for any engine or just ST's?

Status: offline 		I love Super Tigre engines. However, they can be a pain to reset once the low end adjustment is turned. I believe Thunder Tiger engines are easier to tweek, run just as well, and are in the same price range. Good luck.

Status: offline 		Flak has a point. These ST's are not beginner friendly on tuning. You really need to know what your changing on your settings and why as they are touchy with adjustments. Like that flight a few days ago after the 8-10yr idle period. It took me 3 short flights to get the high and low end "balanced" before it would truly perform like a ST. But after that it was turn and burn. I took it out again yesterday and had the whole field to myself. Tore up the sky, must have had 7 flights, and never touched the settings from the previous day. Finding that "sweet spot" on an ST can be frustrating, but when you get it, you will know it, nothing but power and flawless rpm acceleration... Greg

these are great engines for the price. good reliable sport type engines. not the power of higher priced higher performace engines but good for average sport type flying. I have a st90 on a gp extra 300 and it performs well. have a st 61 on a 60 size super sportster and it does a very good job. think you would be happy with this brand. some say the older ones make I believe in Italy are better than the chinese version, but I don't know if there is really any difference. my 90 is the older version but the 61 in the newer versions. workmanship looks to be execellent on both.

good luck and happy flying

Thanks for the advice, Im building a GP Extra 300 64" span and thinking of a super tigre 23cc, would you recommend the 90? Plenty of vertical? Good combo?

the st 90 performs very well with this plane, depends on how strong you want your vertical, my flying is calmer, don't go in much for high vertical performace. the 90 however provides plenty of power for the x300. by 23cc I assume you mean the st2300. this is going up two steps in power 90 to 2000 to 2300. I think the 2300 would give you unlimited vertical. don't think they make the 2000 any longer. I'm very happy with the sp90 on mine.

good luck and happy flying

Status: offline 		Matt,

I am awaiting an extra 300S 64" also, but for the style of this planes performance, most guys put a 4 stroke on it. A lot of vertical climb, thrust, a 91 or a 100-110 4 stroke would be ideal. Tomato, tamato either way will work, its all user optional...... Greg
