The Behotec turbines look pretty nice, and the prices are good. But I can't figure out why more people don't own them????[sm=confused.gif]
Any comments?

Even in the magazine cannot find the description about the turbines.But I bought the behotec for 4.jb180*2 jb130*1 jb55ph2*1.I really think this one is good choice.and everytime I use the diesel with TC-W3 to be its fuel...cheap and convenience more than A1 with turbine oil.

I will be buying a JB180 this winter from Peter at Altecarerc.com. Peter sells the Behotec line of turbines and services them as well. I have seen a number of the Behotecs run without any problems at all. They come with a test run sheet with output numbers and all the stats I have seen have been higher than the newtons they are rated at when test run at about 20 C. The 180 puts out about 41 lbs at 10 C and weighs just under 3.5 poounds and is the size of a Titan. They have a one year warranty and Peter is very good with any warranty problems. I think they aren't advertised enough to be as popular as most others, most of the advertisements are in German which doesn't help. Beautiful engines and no plastic anywhere. The accel. times are very good being about 3.7 sec. for the whole range.

Let me caviat the following with this; I do NOT own one of these engines, but after my friend's experience, I won't be. Let me also say that I am a West coast dealer for Jet Central, so you will assume my opinion is biased.....but I will tell you, I seriously looked at carrying Behotec before I became a Jet Central dealer, but the problems my friend had sealed the deal to stay away.

My friend owns a 66 and powers his Baby Boomer with it. I will let him identify himself if he so chooses. Maybe I'm on the outside looking in here, but he seems to have had nothing but problems with that thing. From failed temp sensors, to not starting, to having to calibrate it, to mailing it top Germany for repairs, I'm not impressed.

The one year warranty is not an added benefit either. Jet Central offers a lifetime warranty and Jet cat just bumped theirs up to three! Also, Jet Central's engine is all metal, and I doubt the plastic starter cone on the Jet Cat affects overall performance.

Now, one thing I can say, is that Peter at Altecare does do a good job of taking care of my friend's problems as they arise. However, when the engine has to go back to Germany for repairs, as his did, it kind of takes things out of his hands.

This is not meant to be a bash at all, but you asked why not and I told you why I would not.

Good Luck

Thanks for the responses - it's helpful to hear different points of view and different people's experiences. I've had the pleasure of buying two Wrens from Peter at Altecare, so I don't have any doubt of the excellent support I'd receive from him.
My main concern is availability of spare parts, and getting technical support from Behotec. I'm kind of a gearhead, so I like working on and tweaking turbines. I'm also looking at the JetJoe JJ-1800, which is another version of the J66...

Now for a completely biased statement.....get a Jet Central!

I own a 66. If I had to do it all over again, I would have zero reservation getting a second one. To be upfront about everything I did have an issue with the fuel pump, it was replaced without question and over-nighted to me the day after Peter recieved my email. I had a second issue with the engine that resulted in a service call to the manufacture. I am not 100% sure what the issue was because of the language barrier. Something became miss-aligned and needed to be factory repaired. I had my engine back in less than 10 days, that includes a trip to Canada, then to Germany, Back to Canada, and finally to me...all at no cost.

Finally, I did have a temp sensor issue...the sensor WAS NOT defective. The issue was me and not properly calibrating the system.

Some of my problems were my fault as I was coming up on a learning curve. As my experience increases, my "problems" are decreasing. The engine runs flawlessly and makes a ton of power. I have over 3 hours on it now and have nothing but smooth sailing from the day I got it back from Germany.

Add to that outstanding customer service and support and I would give the 66 or any of the Behotec engine line. Peter at AltecareRC really took great care of me and he will be getting my business in the future.

That is my experience, I hope it helps.

i have a j66....and have only had problems with it...but Peter made life easier for me....the engine runs ok now...but if i had to buy it again...it would only be because Peter supports it...He is a fantastic person to deal with. Period.

I do not personally own a Behotec engine ( not yet anyway ) but I fly with a couple of guys who do run them and I can not remember a single issue ( besides a bad plug ) the engines run great.
I have dealt with Peter from Alecare and his service is second to none, this guy goes the extra mile every single time
I am building an A D F100 it is one of the earlier kits and I have had many issues with this plane and Peter has dealt with every single one
The kit was not even purchased from him !
There is not one single turbine manufacturer out there who has not had an issue with their engines from time to time, not one

I have three of them, J66HP, JB130 and one JB165, never had an issue, very smooth startup and runs like a dream. i can recommend them.

I'm the guy that had a bad plug. Absolutly nothing to do with the engine itself. The element broke where it is welded to the plug side body, but maintained contact allowing the engine to start and no "bad plug" indication. However, after startup, the element vibrated, metal on metal, resulting in massive RF interference (keep in mind that no matter how well balanced, these engines still vibrate. At 35,000 rpm, even the tiniest vibration in that situation is not good.) Fortunatly, I caught the problem on the ground.

Having said that, and with the knowledge that some may see some bias in my comments (see sig.) I put just over 16 hours of run time over about 65 flights this past summer on my AD Phoenix with the Behotec J66HP. That bad plug was the only problem I had that was not the result of something I did (like forgetting to open the fuel valve.) I will be returning the engine to Peter this winter for inspection and installation of the kero start option.

Although the manual recommends a propane/butane mix for start up, I have had absolutely no problems using just propane (the green Coleman stuff.) I do not use an onboard propane tank.

OK, in all fairness to this thread, I have to come clean with something. No later than 12 hours after my initial post, my temp sensor within my ECU went out, rendering one of my Jet Central turbines inoperative for the day. It will probably call for me to mail the ECU to Eric in Florida.

Karma's a ........

Hopefully Diamondback can contain his laughter......

I have a JB-66, 130, 165, 180.

All but the 130 are kero start and I have had no problemes, that I did not cause. There are a few more Behotec's flying here in Oklahoma with no problems that I know of. Above all else, Peter at altecare responds very quick to any issues that come up, and turn time for service if needed is very fast.

Here are a few of mine

The JB-66 was in my Scorpion but it was replaced with a JB-180 and the JB-66 is going in my SM-F16.

Its all good...

What I did find interesting was how the Jet Central ECU was engine type specific. Now, I am no expert and I only have limited experience but we had to swap out the ECU to determine that it was bad. The system itself gave no indication besides a zero degree temp reading. In the process of trouble shooting we unplugged the gas and fuel valves, we got no indication on the GCU that the valves were disconnected. Additionally, while scrolling through the menu on the GCU I noted that you do not have a lot of user configurable parameters.

On the Pro Jet ECU/GCU you would have had indication that the valves were not connected. Also, it has many options and parameters that can be set and or adjusted. I believe I could have used the Pro Jet ECU on any Behotec engine, all I would have had to do was adjust the parameters for that engine. If my assumption is flawed I am sure you will let me know.

Anyway, a failed ECU is no indication of the quality of the Jet Central engine line, or any other for that matter. Stuff will break, no getting around that. I know that when Sin City has his running it runs perfect....

Well good news, there is a simple reset (that I was apparantly unaware of) and everything is good to go now. No need to mail the ECU away....whew. Still lost a day of flying though [:@]

Good day

It is always difficult to reply to such a thread if you are the supplier, however I have received a few phone calls requesting that I respond. The best way to respond is to state the facts.

Choosing a supplier for your turbine needs depends on a lot of factors including price, quality, support and service.

Behotec engines will fulfill all the above conditions. Should you choose a Behotec engine for your next project, rest assured you will be well supported.

I have been flying a 66 for three years with not even a single flameout. Ensure a good healthy power source, clean fuel, keep your filters clean, ensure nothing gets ingested and you will be very happy with your purchase for years to come. In fact choose a Kero start, and you will not have a failed start.

Hi

I just take a cross read to the instruction manual and found out that the ecu can be run on 7 or 8 cells.

Is it possible to run the turbine with lipos? In this case with a 2 cell battery would not be enough. With 3 cells would be too much.

Regds

Nuno

ECU is auto sensing, 6, 7, 8 NiCd or 2/3 LiPo.
I use 3 cell LiPo

You just need to change menu 90 to 6,7, or 8 cells for the battery alarm.

If you are using 2 cell LiPo, select 6
If you are using 3 cell LiPo (recommended), select 8

Regards

Don't own the engine..but having purchased items from Peter.... I can also vouch for his good service/sales record.

There are no engines that are "perfect".....its great service and support that makes the difference.
(And being able to get and or find parts)

2 Ram 750s
3 Sophia J-850s
1 Amt Usa 280sp
1 Amt 280 NL
1 JPX T-260P
1 KJ-66
1 Pst 600

Nice,

What capacity are you using?

Nuno

I use 2100mAh, 3 cell because I have them, consumption is 300mAh per flight on average with Kero start, typical # of flights per model per day is 5 flights, this leaves you with plenty of spare capacity.

Some people are using 4000mAh.

I too will vouch for Peter's service and help. I have flown my JB165 powered Rookie all summer long with great success! I did have a problem but it was self induced! I now run a 3 cell 1500 Lipo and have perfect starts every time! I have even called Peter on his cell phone on the weekend with a question and he is very quick to respond if he doesn't answer the first time! The quality of these engines is excellent. No plastic parts and very well made. What else can I say, i'm very happy with my engine!!

I would have no concerns at all on spare parts or suppport worldwide for Behotec. I have had a JP66 for three years and they are a super turbine. On mainland Europe they are considered on a par with the very best and used by world class modellers.

posting again to this...

My J66 has just crossed the 10 hour mark and is running perfectly. I am impressed with this engine and as I have stated before, I will own a second one sooner or later.

Not to put the behotec turbine down, but I owned the j-66, Don Perry can probly back me up on my problems, nothing peter objected to fixing, but the starter sliped causing the motor to not beable to spool up to an RPM to start, it was sliping a bit, but it got worst and worst, Peter told use to clean bendix, did nothing, we sent it back and it ran, started great, no screwing with anything. We put it back on my aviation design Phoenicx and put aboyt 30 mins on motor, got down to land and put up elevator in for brakes, I guess I was to fast, dug the nose in the runway, could have fixed the fuse but just sold. I did not have much luck with that dang Phoenix from day one, Don Perry flew it so goed though, I could be mistaken but after we griped to Peter about the The book CG being wrong, and we changed it to fly fairly good, the CG was changed on Peters website. We knocked the gear out of that airplane so many time I stoped counting. Flew good though, just rough landings and the runway I was flying off, grass, did not help any at all.
