Thanks for the feedback guys. 
Azuz,
the retail price in the US region is still $2100US, plus applicable taxes and shipping. The PST guys sound like they're selling every engine they make so mine is still delayed a bit.
I prefer to only sell something that I fly and have experience servicing. I have had some experience with running the early production PST and the AMA engine, but never flown one or rebuilt one to date. For that reason, I've asked my potential customers to wait a few weeks. Sorry for the delay... It also gives me the time to finish off the AMA 520 for you US folks...
If someone absolutely needed one right now, I could check on the current availability for you..
Thanks for the interest in TJT/PST

Hawaii J600's
Hi Chris, By the way nice birds on your web site!
2 J600's flying in Hawaii www.paradiseflyers.org same website as previous post re Hawaii.
My friend own's them and they perform great. One is in a Avonds F-15 20 lbs, i think. Fly's great gets off of grass. I have a F-15 with a 750 F in it and my takeoff performance is better, but the top speed is similar. I do however have better vertical, but not by a huge margin.
His other plane is a Yellow F-16A. That also gets off the grass and it gets going in a hurry. Great performance on both motors. He has earlier versions with the Orbit controller with optical rpm pickup. You have to make sure you do not have the sun shining on the pickup when you fly or start. I have heard the new tems unit solves that problem.
F-15 must have around 20 flights at least with the J600, and the F-16A 10 to 15. Engines have been running perfectly.

Aero65.
Correct, the new 'TEMS' units do not use an IR system to measure RPM, for the exact reason you mentioned. If the sunlight (or even a faint reflection in the right situation) hits the collector just right, it will saturate and not be able to distinguish the visibility of the emitter through the compressor nut. In this situation, the only safe thing to do is have the ECU shut down the engine.
The TEMS units have a magnet buried in the compressor nut, actuating a small hall effect sensor board in the front cover. (same as the TJT-3000) This is the same sort of technique used on many other successful engine brands, totally eliminating any flameout's previously seen with the IR system. Although similar, some models of hall sensors will vary in the level of signal amplification to get over cross-talk generated by starters, glow circuits, pumps, etc.

Hi Guys
My geography is not great but we have three of the PST J600 turbines flying in Central Scotland. No problems only praise for these fantastic turbines. Mine start first time every time. I have mine installed in a Philip Avonds F15 and it has had 10 very great flights to date. The other 2 are on the back of I.A.D. Model Designs Serpents Sports Jets.

PST J600
Let me know if you want to beat the post AMA approval rush at the end of November. Mine is flying great on my ROO. Delivery time 5-7 business days from reciept of order.
Also just to clarify TJT/PST US sales reps at present have not been confirmed. At present TJT/PST is asking all inquiries and orders to be placed with your nearest regional rep. If you are in the U.S. or Canada. Please check http://www.TJT.bz PURCHASE INFO PAGE for your closest TJT/PST rep.

ECU interference
I am impressed with the degree of satisfaction that everyone is having with this turbine. I am interested in hearing about effects that the ECU is having on radio range and if there is any interference. Jetcat has certainly set a new standard with their latest ECU in terms of this. How does the TJT compare?

Re: ECU interference
Woketmans Isobar has had no effects from ecu rf. We have been flying rock solid with the Profi 4000, with no problems. Flew it today with a wireless cam on it, and it was AWESOME! He's got a 3000 in it, with the tems unit (same as the 600, correct me if I'm wrong)!

Mike, I (legally now!) get unheard of range with the TEMS ECU (and got the same awesome range with the FADEC). Of course I cheat cause I am flying the MPX 12 ch Profi 4000 with the 12 ch receiver. The 2.4 GHz wireless TC camera did not bother it a bit either. I also use a Jet Team Liebetrau vertical whip (non-base loaded) antenna.

First, before I forget... Woket, send am an email with the details of your camera. I'm interested in hearing more about it because I have a non-R/C application waiting for one. I'm, also looking at the one in this month's RCU mag...
Anyhow, back on topic... ECU's. Here's what I know...
TJT/PST have stuck with the simplistic approach to guarantee the reliability of its ECU. We only provide engines with the proven hall-effect RPM measurement system, avoiding the associated flame out problems with the IR detection systems. We also do not include any extra non-essential features in favor of simplicity. Speed sensors and smoke systems can easily be found through 3rd party vendors like Tam and MiniHobby. As an ECU grows in its features, the circuitry becomes more complex. To effectively reduce EMI, manufacturers should be minimizing the run length of the paths on the board and matching any clock speeds to levels that do not produce harmonics in or near any R/C frequency band.
The other harmful effect that an ECU can have on the R/C system is the transmission of interference through the connection to the RX. There are 2 well proven methods of reducing this: (1) a ferrite ring added to the ECU <--> Receiver cable acting as a low pass filter, designed to limit transmission of high frequency noise and allowing transmission of low frequency servo PWM signals. This is the way Gaspar did it in the well established FADEC ECU... (2) Optical isolation... As I understand it, the TEMS ECU has two completely separate circuits in the one package, the receiver side and the power side. The RX signal is converted to a light pulse and re encoded to electrical signal on the 'power' side of the ECU. In effect, this is like adding a 1-way valve for interference.
I included a simplified EMI test report in my AMA 520 doc for the TJT-3000. This test data is also applicable for the system included with the PST as it's the same hardware with a different set of customized software codes. The report clearly demonstrates the lack of interference in the 72Mhz band, along with 40, 35, etc... Following that, I think JonD/Marty fly on JR 9 channel units, I run a Futaba 8UAP, Chrism runs Graupner, and I think JohnC runs Airtronics... No problems with range all around. Given that we feel our ECU is sound, we prefer to spend more on the engine technology and its evolutionary development.
If any of you would like more info, feel free to give me a call (604) 592-0994. I'd be happy to answer any questions and further discuss the technology used in our ECU's. There's only so much you can do in a type written forum.
Thanks again,
Kelly

Kelly, I received one of the EyeCams ( http://www.rctoys.com/microcam.php ) that I heard about here on R/C U. It works good. I think there claims of S-VHS resolution and range are exaggerated, but it still works well. It has a CMOS imager, not CCD. It sure is fun. I intend to try putting it on a trainer soon (glow, not turbine) and try a flight while only looking at a TV, with a safety pilot on buddy box, of course.

Kelly, we've been shooting MTB video with on of theses http://www.microvideo.ca/6470cam.htm . Seeing our film at a local theater, I was surprised by the quality! Give them a try, good guys to deal with.

Hi guys,
PST export more than 10 J600s to the USA and not counting those that were carried from Thailand. We are working on the AMA issue and soon you will see J600 flying at major US jet events.
Wish that all jet flyers are on the RCU but some just not the internet or computer wize type.

PST J600
Hi Guys,
I'm the guy Duke (Aero65) mentioned. Have 2 J600's which I picked up in Bangkok in April. Couldn't be a happier camper. This engine is a perfect replacement for .91 DF plant. 41 flights on the two so far and no glitches except for the sunshine issue Duke spoke of. That's easy to fix with a hatch for the Orbit, and solved with the hall sensor on TEMS. I plan on flying mine with the Orbit until overhaul time when I'll switch over to TEMS.
Had the privilege of spending all day Sunday with B777, Pornchai and some of the PST gang at their field near Bangkok. J600 powered the Avonds F-15, Yellow F-18 single, and two Roo's, all with authority. The TEMS unit performed flawlessly in B777's F-15. Also DF Yellow F-4 and Panther with AMT flew well. (Pek's Yellow F-4 DF is by far the sweetest flying DF I've ever seen.) Thanks for the awesome hospitality and airwork everyone (these guys do low passes you've got to see to believe!!!). What a hoot.
Email me if you have any specific questions or I can post for the group. Aloha,
Woody.
