Just flew their 120 in a fourstar 120 today for the first time and of course, started with ONE flip,incredible power,and such a low stable idle, I was scratching my head!!! Quality compared to my jett 50 at least! GP 42, & pro 46 SAMETHING!!!!!! Don t you know thundertiger you should be in all the magazines with their perfect reveiws to be that good! Charge alot more for your product like os.All your engines cant run that good with just a small add in towers!!

I have a couple of the TT.40 Pros I purchased after reading a .40-size engine comparison test in MAN years back. They are the most user-friendly .40s I have. Stronger than most of the .40s out there, too. I added a .46 Pro later that season: another "best buy" for sure! Cheap, strong, dependable and durable.

Good flying,

You betcha!! But not just a good buy,but ONE of the best m.f.g of rc engines period!!! Very reliable idle and midrange makes for fun rcing.

The TT120 is a brilliant engine, I think the only reason its not 'known' is because no one really use 120 sized engines, most get a 160 today and its the OS. I loved my TT120, easy start and solid idle, sold it to a friend who begged for it from me. This is a double thumbs up engine! The 46 is the same.

What are friends for TIANCI!! What I cant figure out is why are their engines so good. Or what do they have that other engines lack of. Is it design,or their high certification in mfg, or both.Goes to show you what good rc engines should cost if you dont spend alot of money for advertisements and pass the savings on to the consumer.Have had alot of os. supertigers,asps.k&bs and sold them all.Their IS a feel of thunder tigers that is so different.Must be the compression.Tell you what it has changed my flying alot.Touch and goes over the runway at idle,and the best landings ever. Throw a large diameter prop on a motor with a super low idle and will just about slow any plane down to a crawl for a landing. KELLDOG

I like Thunder Tiger too. The engines just idle and transition better than OS or other do. Also, Thunder Tiger's let their quality do their talking instead of placing adds in ever magazine printed.

Hi,

Where can I get a TT 120 (2 stroke I assume)? I have searched several websites and found nothing!

So I am now thinking Webra 1.20

Thanks,

Chris.

Is there a 120 size 4*? Desmobob, do you have a desmodromic valve train in something?

Purchased mine in a hobby shop.200.00. They are around in websites but are hard to find. Was looking and thinking about a webra too but went with the mfg that I had experiance with and very glad I did. I think I read that if you get a pump webra they clog with castor goo and need to be cleaned often. Please check me on that or somebody else has advice. Have a foremost check valve on pressure line and does the job well as it does for many large engines and small engines. Some engines and set ups it doesnt work at all. I THINK large volume mufflers just cant get the pressure around all throttle settings without restricting a outlet like on a pitts muffler.Then you resrict the engine and in MOST cases loose power. Letting things work for you with the least amount of parts held together by fastners and keeping it simple and durable by design and build keeps ya in the air. My g 26 on my stinger 120 is another example. Spit at it and she will start. Just a little more weight but not one deadstick or glitch on dozens of fights. Hope ya have luck with the webra guy, but hard to go wrong with thundertiger. kelldog

And their 4 strokes are the same.
Why would one buy an OS Surpass when the TT equivalant is just as good and for far less $$$$

kelldog

My Feedback: (1)

Woody, Was always wondering how their 4 stroke performed as after many 2 strokes and gas engines wanted to try a 4 banger.Does any one have any other input on it. Not just on price but comparible performance to saito, os and the like.I do think thundertigers design enhances more on the side of idle and transition with a LITTLE amount of decrease in power.They get stronger every flight for years ,were as OS looses power. OS is great out of the box though.After flying for over 20 years ,I do think thundertiger makes some of the best engines you will see at the field.Not the most prominate engine because their just is not much profit in selling them.Good price is the cherry on the cake.Can not ask for more when it takes my 120 unlimited vertical and runs the way she does for under 200 bucks and know she will only get stronger!! HOW is their 4 stroke guys.Never see much on the forums about them. kelldog

The TT91 4C of mine turns an APC 15x4W at about 10,250 RPM. Not bad for some 'cheap' engine.

My Feedback: (1)

YIKES!!! That sounds real good but how does that compare to the other boys?? kelldog

XJet

I've got a TT91FS and it's a nice strong engine but took a while to settle down.

Mine turns a Master Airscrew 13x8 prop at around 10,500 on the ground (richened 300 RPMs off peak) and pulls my 60-sized P51 Mustang along almost exactly as fast as another in our club that's powered by a SuperTigre G90.

The TT 4-strokes are not as nicely made as Saitos but cost a *lot* less.

The other downside of the TT91FS is that it's quite a heavy engine -- about 26 ounces I think. By comparison, my Saito 100 weighs under 20 oz. For warbirds and sport-type aircraft the extra weight isn't a problem (might even be an advantage) but for 3D stuff I much prefer the Saito.

The other great thing about the TT91FS is that it is *really* economical on fuel.

Even though it provides the same performance as my mate's ST G90, I get twice the flight time out of a tank of fuel(our P51s are identical in all other respects).

I'd say that for the price, the TT91FS is very good value in the world of 4-stroke engines.

if you guys are wondering how tt engines run as good as old os used to just look at who is thier head designer, Kaz mihara. funny how after he went to tt os has turned out a bunch of lemon/ troublesome engines. fx liner peeling issues, 91 fx overheating issues, 70 ultimate problems. etc.do you think there might be some connection here?

tIANci

The TT91 4C I have is a second hand one, its about 5 years old and the liner was changed along with the bearings. This engine runs so well and like what XJet says, it really sips fuel. I got the G90 ans I sold it away after like 2 gallons. Its really a waste of time to own that engine as far as I am concerned, the TT engines really kick butt for their price. In Malaysia it is the leading engine for RC planes, out sells OS many many times over. Its also a fair amount of $$$ cheaper than an OS.

If only TT makes their 91 2C more available and also a nice 108 2C and perhaps some good 120 4C.

YES!! Wonder how many rcers know that! Sounds like os is bilking their reputation of the past just like harly davidson motorcycles did years ago. Dont ya just LOVE CAPITALISM!!! Just cant rely on big adds in towers for guys that have been around the horn with engines. BUILD IT AND THEY WILL COME!!! KELLDOG

Alright all you TT fans, I have a problem with my TT .61 Pro that I could use some help with.

The engine is brand new...I have run about a tank and a half through it. It will start easily, idle fine, run up to mid range and even rev to full but then dies as soon as it reaches peak. I have moved both idle screws in every direction with no improvement. I have changed the line inside the tank. I have checked to make sure the crankshaft cover screws are tight. I have compressed the O-ring when installing the carb to insure a good seal.
I don't know what to do next.

Any suggestions?

I love Webra engines, but get the Thunder Tiger 1.20. It is more powerful, lighter, runs just as good as
the Webra and lasts a long time.

The only negative about the TT 1.20 is that goofy muffler arrangement. Not to worry, it is workable and
usable. Just goofy.

How about posting a picture of the goofy muffler if you can. I just ordered a thunder tiger 1.20 yesterday.

1ntree, sure as anything not enough fuel supply.Do the pinch test on the line to make sure. Position of tank is very important with a 120 and no pump! Please no matter what install a foremost one way check valve to increase tank pressure. You must undo it to fill the tank.Get high speed first then idle.Gotta believe that large chamber on the muff is hard to give proper pressure to the tank on SOME of the setups. EdCregger she is a beast of a muffler but how many give you the option to turn 90 degrees on a stock muff. Wonder if jett mfg can do anything with their turbo muff? Really hope I am right on my suggestion and it works. Not just my new 120 but 3 others run better then one could ever hope for. Hope somebody else can help you on this thread if they have any other thoughts. CLUB THUNDER TIGER KELLDOG

WHOOOPS!!! SORRY 1ntree noticed after, you are talking about the pro 61. Still would suggest the same thing. HAD the gp 61 for hundreds of trouble free flights until a new flyer found out 2 planes cannot fly on the same channel. Ultrasport 60 kit was a great flyer. It was a bad crash! LAST PLANE I WILL EVER BUY FROM GREAT PLANES! Dont care what they sell! Cant count on them.Change like the wind.They develope a good plane and just as you are getting a passion for it its GONE!! Went to get another one and they took it off the market. Ya all know my favorite brand engine is so I might as well tell ya my favorite plane co. is. SIG MFG.!!!! Wanna go FAST? Try a sig kougar with a jett mfg 50 !! Hope you have good eyesight! Thing is that gets me is it flys like a trainer. PROVEN planes and designs throughout the years. KELLDOG

Take note the TT 1.20 is actually 1.27. And it will run on FAI fuel. Latest reading is here is:
APC 17 x 6 = 9700 rpm, 5% nitro, Sonictronics 310 plug
APC 16 x 8 = 9200 rpm, 5% nitro, Sonictronics 310 plug
Will be trying a 18 x 6 Zinger wood prop in the Spring looking for 9000 rpm.

And yes, almost all 18 of my engines, .36 and up are TTs. But the .61s are slowly beng replaced by the GMS .76, the only worthy replacement.
