I just received the new TJT 3000 and I am very pleased the way
it was packed and shipped promptly from Australia. It arrives in
a nice aluminum carrying case that can be used for support
equipment and transmitters later on. The service has been
excellent , the best turbine purchasing experience I have seen
to date. Looking forward to test runs this weekend.

Happy TJT 3000 Owner

I have made a test stand for the new TjT 3000 that I can check the thrust of the turbine. I hope it will be all set-up Sunday afternoon, here are some pictures of the test stand and the turbine installed on it. This will be the future for new turbines.

After setting up the ECU, I proceded with the first start up and
the Turbine started perfectly, and it is performing to all manufacturing spec. as indicated. The support I have had from TJT is excellent. If you're in the market for a new turbine, take a real good look at the TJT 3000 Eagle. Web site - www.tjt.bz

Congratulations WD!

Here's a photo of the engine I received last Wednesday. It ran on first attempt and kept starting every time I pressed "allow start". Behind it, is my older TJT3000 with Auto FADEC by Gaspar Espiell sitting happily on my HS. Both engines are super runners, but the latest one with the TEMS ECU is really a gem.

Thanks Chris, you really made me happy with the last shipment.

BRG,
Chris

I test ran the TjT 3000 Today 10 times, and each time it started perfect every time, at 126,000 rpm's I was getting over 27 pounds.This is a great turbine, and I hope to have it flying soon.

That's great WD40!!

If your set up is accurate to about 5%, then at 126k you are getting 27 lbs of thrust. Assuming the data given to us by Jetcat is correct, the P120 has 26 lbs at 120k. As a customer, I would like to see the thrust on the TJT be higher at 126k or a 27 lbs thrust at 120k. Physics laws dictate that under SAME CONDITIONS and design criteria, the lower rpm motor will last longer!!!

Please let us know the results when you fly it so we can collectively make some intelligent choices!!!

I would also like to hear abt the test results. WD40, what is the spool up time like? We hear the TJT's spool up at abt 2-3 seconds from idle to full power? If this is true, its amazing. Have you used Jetcat? If you have, how do u rate the TEMS with respect to the jetcat ECU? Does the TJT ECU have all the engine management features like the jetcat? I am not talking abt smoke, cruise control etc. Im talking abt real world engine management software.

Have you been able to test fly yet? How did it work out in the air?

I have the Artes 3000 Eagle which I got to assemble. It goes together perfectly, and once assembled it runs just like everybody else says, It starts up easly and I am useing air start with only the semi-auto start up. Building the engine gives you the control of maintence of the engine. Look up Artesjets.com and see for yourself!

IS that the same turbine as the TJT? I know one is a kit but I dont know the differnence.

As for the TJT I have not heard much about them and wd40 seemed to be having some success

Hi Mark, Yes the AJ/TJT engine and the Artes 3000 eagle are exactly the same to my knowledge other than the Artes engine comes as a kit to assemble by the buyer. The 2 companys together manufacture the parts and sell them in their own versions. Tom Cook of Jet Model Products was supposed to import the AJT version into the US but did not for reasons I dont know. I bought my engine directly from Artes in Spain and Highly recomend it. It was extremely interesting to assemble to better understand all working parts and to help understand future problems and maintenance later on. There might or might not be a difference in the electronics sent with the different versions, all I know the FADEC electronics sent with My Atres 3000 eagle are very easy to set up and adjust and simply a piece of cake to operate the engine with. I cant wait to fly the engine

I think the lousy flying weather this time of year may have a lot to do with it....there is just less flying activity over most of the continent.
I got one with the new burner can just waiting for some good weather so we can run it on the test stand. I'm really anxious to start making kerosene fumes, but have to defer to the 150% humidity we seem to be getting these last couple of months (ie rain, rain and more rain...)

JET FX

Randy- You are right they are similar engines with different ECU's eg FADEC for Artes and TEMS for TJT. The TEMS ECU has greater user versitiliy with 20 various parameter settings. There are some minor internal design variations as well.

Hi WD40,

Where did you got the thrust measuring scale? My home made test bench uses a spring with a calibrated scale but it can run out once in a while, needing regular calibrations.

Gerald.

Check out my latest creation, KJ-100. One of my KJ-66 modified with larger comptessor just like the P-120, JG-100, RAM1000 etc..
Most components homebuilt, thrust up to 13.5 kg. (30 lbs)

I am now getting 30 to 31 pounds out of the TjT 3000 The temp out side was 40 degrees fahrenheit, and scale came from Wal-Mart it is just a fish scale.

Just to clear things up yet again...

As a few reps and others have already noted, the TJT and ArtesJet engines are not identical. As Marty pointed out, the ECU's (FADEC vs. TEMS) are totally different although both are pretty good products in my opinion. Other than that, several people (including myself) have spent the last year tweaking the TJT design. Many of those people have no affiliation with ArtesJet and such these changes are not in the Artesjet product. On top of that, the AMA application I wrote does not cover the Artes Eagle as a kit or production engine.

The results of the evolutionary changes (such as the burner can that Nony mentioned) are now evident in WD40's testing results. Also of note, we no longer place a restriction on the full throttle operation of the TJT-3000. Previously we shipped engines with the limitation that the engine should not exceed 120K for more than 2 min per flight.

As per standard TJT practice, the engines are fully retrofitable to the new design should any customer feel the need to upgrade. For obvious reasons I am not going to go into detail about the rest of the changes.

Hi, Would also like to let guys know the new 3D ics ecu is coming with all Artes Jets Eagles this is a very neat Ecu and has the latest auto programming and is micro small,The Eagle from Artes will be Ama Approved quite soon and yes those TJT are a separate deal.Glad to hear all the Guys with Artes Eagles are batting a 1000...

Hey Paul;

Did you fly your turbine at Arizona? how did it fly? I hope you got some more good data for us to compare to the P120 and TJT 3000. Having 30+ lbs of thrust MAY give Jetcat's P160 some competition... Let's us know! I am still waiting for my P160's. Jetcat's web site says they are (P160) trickling slowly but should inprove in time like the P120 perhaps!!

Hi Ehab,I was unable to furnish the F-16 due to the right stab bouncing.I had a set of 8411s and the slop was to much so Ive replaced the Servos with Volts Aluno Stars and fixed the problem, Its ready to fly and Im now fitting it with the new ICS 3D ECU.Latest News....I have had the opportunity to meet with Mr Artes and his son Sergio,and their factory manager Felipe they are outstanding Highly Knowledgeable group of individuals and are on the leading edge, remember they were flying turbines wile we were still getting are hands all oily.Artes Jets are producing now production motors and I have seen their new motors including the Bee motor see pic, this is not another "Ram 500" knock off but a smaller more advanced and fully tested motor with smart Ecu ICS, The Bee is 12.5 lbs and is in full production.Artes and his group have set up a production facility ISO 9000 rated local to us here in the United States where all motors are being produced and fully assembled, guys will be able to purchase fully assembled and fully transferable warranty motors and they will need less parts to be replaced due to their advanced design.

Hi Mike

I'm not knocking TJT here, but when your doing your thrust measurements, you have to take into account air temperature and adjust your numbers back to STP(Standard Temperature and Pressure: 15C at Sea Level).

Earlier you posted that you were getting 27lbs at 126K and I'd guess that the temperature was about 60F(15C). Your now getting 30-31lbs at 40F(5C). The colder the air charge, the denser the air, the better your combustion, the more thrust you get. For turbine engines, regardless of size)there is approximately a 1% change in thrust for every degree celcius difference above or below 15C(60F). If I use your 27lb measurement from earlier on and make the assumption that that was measured at 60F(15C). Your new measurements at 40F(4.5C) of 30-31lbs fall into the 1% thrust per degree celcius change formula within +/- .5 lb. If you extropolate that to say 75F(24C) you'll only get about 24.5-25 lbs thrust.

Again, this is not a knock on TJT . What I have stated above affects every turbine manufacturer, Big AND Small.

SimJet turbines are affected in the same way. For example we(GNM) rate the 3000AES at 28lbs at 25C(77F) or 31lb at 15C(60F). At the moment, they are putting out 33.5lbs at 5C(41F). All the thrust numbers are within +/- .5 lbs.

I hope I have added some insight into the different thrust levels you are seeing. If you have any questions, please contact me off line.
