which engine?
 

Hi,here I come again.I made fwe bad threads about p120 and similar engines tha are too expensive for me.I am buying jet in february,jetmach super sport and after it,I am going with avonds f15 or f16 and FEJ bae hawk(for 80-120N turbines).
But I didn't choose my engine yet.Till then,I'll have about 1720 eur(but would prefer that engine is in =<1600 eur price range)There are few options.K80(1350 Eur),P80SE(1639 eur),RT 80XL(1466 eur),RT 130XL(1592 eur) and ATJ 120ti(maybe,for 1750 eur).
<!1600>Basically,I am looking for urbine that will serve me for some years and fly mentioned jets well.Which one is best or,do you guys have some better advice?
Thanks in advance,
Adrian

PS:Sorry for some "lost" letters,but my keyboard is missing few buttons.

RE: which engine?
 

My advice would be to go with the King Tech K80E. If you are on a budget you cannot beat the value of the K80 engine. Unlike others I have owned in the past, this engine will start for you every time, it has great throttle response, net weight is lower, higher thrust, good fuel consumption and alround excellent fit and finish. Moreover the service level is excellent.

I used a K80E in my BVM F80 for my entry at the Jet World Masters qualifier and it performed flawlessly.

RE: which engine?
 

Yes,I am thinking seriously about K80E,but I'm not sure would it have enough thrust for my future projects.Since I am buying in February,P100 should be out and P80SE could drop in price or even P100.K80 is a great engine too,I saw it on the youtube and it flies very well.JetCats are of course, great engines.Hammers should be ok,too( German quality,and chrigui said that his RT 130 in T45 works OK) .
Andy,does K80 has 82N or 75N of thrust.Olivier said that he measured 75N on his test engine.

PS:I forgot to say something.Another jet that I would like to have at some point in the future is F86(the one for 80-120N turbines,not sure which manufacturer).

RE: which engine?
 

Go with the P80 as it will be totally reliable and powerful enough to fly a lot of different aircraft

Jet Central Cheetah...

RE: which engine?
 

If you are on a budget, you can't beat my ad on a very reliable engine on the turbine classifieds...

RE: which engine?
 

What about the Black Mamba? 30lbs thrust, around 2500-2600US? Might be a little more than planned but.

RE: which engine?
 

I'd go rabbit or cheetah.. or even a behotec ..

RE: which engine?
 

You'll be paying a lot more than you want to spend to buy a Jet central. If you want something in the 30lb range at reasonable prices make sure you have a good look around. Talk to people actually flying the engines.

Its the only way you will get unbiased opinions. We dealers can tell you all day that the engines we sell are the best but until you actually speak with the end user its all pointless.

My 2 cents.

RE: which engine?
 

84.5n or 19lbs.

RE: which engine?
 

Good point, and even more for a Jet Cat. If I have my info correct, the Black Mamba is really a re-done older generation TJT something or other...basically quite similar to the old, original Super Eagle. The Mamba I believe has the "old style" stainless steel combustion chamber ETC. While it is a proven design, it lags the new generation of turbines that employ inconel (did I spell that correctly?) in the construction, plus the fuel economy is worse than the "new stuff".

Now, it is cheaper, so if money is the bottom line...it's a looker.

Guys flying King Tech love them too...and it's a great price...just not in the thrust range you need down the road.

King Tech, the Mamba and Jet Central all use the same ECU so that's a bonus...they all work well.

In the end, they are all good...just some are better than others...and you ultimately get what you pay for I guess. Sometimes it's cheaper in the long run to just buy what you really want/need and buy it once than buying "something acceptable" the first time over having to buy a 2nd engine later to complete your 2nd project.

Lastly, consider a turbine similar to what your Mates are flying and are happy with. That way you can get help with it if you need it.

Cheers,

RE: which engine?
 

Hi Beave, could you share with us how the mamba lags behind the newer engines?

Edit, just realised you are a Jet central supporter. Surely this is proof it doesn't 'lag'?

RE: which engine?
 

Wren 120 is lighter and shorter than a P80 and flies a 80-sized and 120+ sized airframes. Also the P80 SE has more thrust and better fuel economy than the K80- it is also very silent and with kero start. Price is almost as low as K80:s. We have no K80:s probably becsuse the P80 SE exists. The new Wren 100 is also worth looking at.

TP.

RE: which engine?
 

I cannot fault the ATJ 120-ti just under 3 hours run time starts great runs cool and puts out as much as a Jetcat 120.

RE: which engine?
 

Wow!I didn't know that I will get so many answers.I have to say that jet central is out of my reach.
So,with P80SE,I will be able to fly more airframes than with K80?Wren 100 is out of my reach,even if it is same price as supersport.
I can wait for P100.
Wren 70 no way,too weak fo my needs,I think.
P80SE is 289 eur more expensive than K80(K80-1350 eur,P80SE-1639 eur).

Hi Molo,

Please don't start a flame war here, I was just pointing out some differences. Correct me if I am wrong, as somethings read online and in pubs are not factual like they infer. The Mamba is the old TJT engine, which was more or less the original Super Eagle. The Mamba uses Stainless Steel in the hot section instead of inconel as is done now and SS does not last like Inconel does. Also, the specific fuel consumption per pound of thrust higher that the newer brands available.

It's like going to your local motorbike dealer and seeing two brand new Gixxer 1000s for sale, one a 2008 and the other a 2011. Yes, they are both good machines, and the '08 is cheaper to buy, but the '11 is just more advanced, refined, technically up to date ETC. That is what I was pointing out. I had an old Super Eagle in my F-15 and it was a beast. When I sold it (10 hours) it was still running like a bull so I am a tremendous fan of the design (honestly, it was probably the best starting/running engine I have ever owned, and I have owned Jet Cat, PST and JC) but there is stuff out there now a days that might fit the bill better.

Cheers,

Beave

Adrian,

The P100 is probably your best bet. Planning on flying (in the future) a jet that calls for a 120 with an 80 typically yields less than stellar results. Heck, I know of a Duffer who flew an old SM F-15 with a Super Bee. Yeah, it flew...but that was just about it. Getting the 100 would be a great compromise...enough for your 120 sized projects down the road, and made with the most advanced materials and designs available today plus it should fit your wallet's desires as well.

Good luck,

Beave

I just wanted to pass this along and make your own conclusions.

First off this guy is only 17 years old. He lives in Croatia, not New York.

In other threads he was going to buy a JetCat, then a JetJoe, then a RT Hammer and a K80E. Then was going to build his own turbine and had everything needed except a combustion chamber and a needle ring.

RE: which engine?
 

Ah hah! Good work Bob. OK...I'm done. I did see his NY address but posted Euro pricing...

Beave

RE: which engine?
 

Bcovish,why are you spamming my thread?Please,leave me alone.
Bevar,P100 should have about 24-25 pounds of thrust in P70 size.hat means that it would fit in smalle jets like tamjet A4.But,if it doesn't come out before february,I think I'll go with P80SE.It is proven design and can be made as kerostar(though P100 should be internal kerostart?)
Anyway,I appreciate your help guys.We will see how will situation go on.

RE: which engine?
 

.
Even if you don't want to help me any more,I got my answer.P80SE or P100.

RE: which engine?
 

Call it spamming or whatever. I was just pointing out what you had posted in the past starting in April of this year. One thing to think about is that every post you make on RCU is able to be read by anyone here no matter how old it is.

I wish you luck in the future in whatever you are trying to accomplish.

RE: which engine?
 

Double post :-(

HE'S BACK !!!!!!... Going to get my goloshes and my electronic fly-swat !!!!! LET HER RIP TATER CHIP !!!!!!

RE: which engine?
 

Interested where you got your info bevar, not to start a flame war just as I am curious as the info is wrong.

The 'newer brand 'Jetcat 120 uses 12oz/min, the mamba uses 11.6oz/min. Not much difference and nowhere near the Super eagles 9.1oz/min but still less than the Jetcat.

Just like to see the facts laid out before heresay.
