I'm SOOO happy you awoke in such a cheery mood Dave... I wouldnt have it any other way. Now, All I hear is Bla Bla Bla from your previous post...Looks like I struck a cord with the Santa comment... Thats too bad, I do apologize and promise I wont strum it again. Now, as far as personal attacks I do believe that when you refer to peoples property as junk it would offend the owning party... I dont know though, why dont we put up a poll on that one as well while were at the ten other meaningless polls you want to start. Listen bro, I'm done here and this will be my last post in response to you. All I'm sayin here is that if you dont like this engine, fine, how about you post somewhere else about your dislike...why in this thread where people are trying to figure these engines out..WHY.. I dont understand. Your useless rhetoric is only here to offend the people and if you do it again I am going to report you... Kapesh, bro??


Luis

I'm not even gonna try to comment on the 'junk' comments..

I started her up today for the first time. Ran fine. Scared the S@#t out of me (in the backyard)

Solenoids indeed are not top notch quality, but franky I couldn't care less. The Nades ECU is what I got with it, no preferred option.

Engine runs smooth, no vibrations at all. The only downside is the cold weather - the glow plug didn't seem to get hot enough every time to ignite the gas, but a lighter up the back helps a lot. I also noticed the popping when gas keeps flowing, I think my solenoid is reversed as well, but I just turn off the gas when the fuel ramping is around 30k.

Flightwork pump works great as well.

That's just my experience for now. If it lasts over 15 hours without major maintenance I'll let you all know.

For now, I'm done with this bashing thread. I know all you A-brand turbine guys don't like the JJ's. I got your point. So get off it, I like mine so far.

Off now, I wont be posting here again any soon. (heck, maybe that's the reason for the lack of success-stories, they only get bashed.)

Luis,
I'm not going away. Can you tell us YOUR experience with JJ1400's? How many hours , or minutes, did you get before trouble began with your JJ1400? Your reply is awaiting....

Dave

I smell a troll...


Happy New Years Everyone

Luis

I didn't think you could tell us your experience as requested.

Dave

This Dave guy Busts balls!! Why??

Is this for the 1200, or 1400 ? ? ?

" That's just my experience for now. If it lasts over 15 hours without major maintenance I'll let you all know. "

Hans, please come back with more progress reports, and ignore the idiots.

Dave, FWIW, Luis is a personal friend of mine, and so is Gabe. I have always respected and trusted your advice and persona in the hobby. Suppose I had a list of 30 guys who do not have any problems with their jetjoe engines, what happens then?

I have seen these engines from about the third month, I was one of the first 10 guys in the US to run one. The problems I had with the first runs on the 12lb were mostly electronic related not engine related.

Actually of all the engines and runs and flights I have seen, the engine itself is well made. I think all the problems I ever saw were ECU related. None of us are "experts" at fadec ECU. I'm still learning how to tweak certain things.

I don't think any of the jetjoe owners or sellers, etc claim that the jetjoe engine is an original design, from what I understand it is a copy at least in some part or fashion of the wren.

I have read your posts over the last year or two related to this engine, and I always assumed that you either had some tie to wren, or simply bashed this engine for the sake of maybe you lost an airplane to one or something like that.

All I can tell you is that Luis is one of my favorite drinking and flying buddies, and I would think you would respect me enough to know I don't hang around with doofuses. I have spoken to Luis and told him all I know about you, and I can certainly understand how he felt he was dealing with a moron by your posts. I just read your posts and I can see his point!

Anyway, fwiw, get over it or come clean as to what reason to keep asking for reports of guys, cause really, even if you had that information, would it change your mind?

These guys are just trying to get these little engines going, give them a break and lets see what happens. I can assure you, I have witnessed several sales of these engines, and wren was not a contender for the money if jetjoe wasn't. Down in this area, jetcental would have been the next choice. I don't know anyone in Texas running Wren, and there are at least 75+ turbine guys in this state.

Hate to ramble, but like and respect you both.

Sean

OK - I tried to avoid commenting on this continued "bashing" of JJ engines - but PLEASE, enough already...I personally own a JJ1400 & JJ1800. The JJ1400 has over 10 Gal of Jet A through it & it runs great. Yes I've had problems, but the problems were caused by me because of my lack of knowledge and operations of turbines, i.e., hot starts, messing with ECU settings, etc...and yes I had to replace bgrs due to hot runs. But I've learned so much from these fine turbines by tinkering with them. To me it is part of the hobby. Just imagine if you pay $4000+ for a turbine & had problems - you'd loose interests right away. Thank goodness for JJ and keeping the cost down so EVERYONE can now experience turbines without taking out a 2nd mortgage or getting divorced...

This thread was intended for JJ owners to share their experiences & help each other. If you want to bash JJ, then please start your own bashing thread else where and not here. Don't want to speak for anyone else, but I just want to have good input from others and sharing of experiences so we all could benefit from one another. My 2 cents...

Luis,

AMEN!!!!

Good to see you guys putting your heads together & working through the problems with these engines. Isn't that what a 'forum' is about? An exchange of ideas?

I believe that eventually, with enough determination, the problems will be sorted and the engines will be good, reliable performers. And a 54 page thread shows the determination is there. Posting on the owners thread telling them what they already know, that there are problems to sort, is no help at all. - John.

This thread was to support, assist and to pass some turbine knowledge to JJ owners. Any valid JJ bashing was from JJ owners who had mastered the defects and the lack of Quality Assurance-Control at the factory. Some improvementa are now becoming apparent in that there are at least some basic instructions given in the box. Some day the Chinese fuel pumps will either improved to be adequate or be dumped completely. If the Chinese seleniods are only valid in one direction, then in time someone might take a marker pen and put an arrow on them to show the right orientation. Also newer JJ turbines do seem to be being test run before despatch, instead of relying the new owner to test them out.

That said you pays your money and you take your chances, if it doesn't work out you can always come here. FWIW running 900 (15hrs) minutes is a hell of a long time flying in the air, before reporting back here. I'd suggest any JJ owner who had 120+ minutes flying was fully operational, though many who fly JJs weekly will never post here.

So far we have four JJ1400 and one JJ1800 in Israel going strong... time will tell i guess.. hehe

fw190pilot, you hit the nail on the head - the gas solenoid was reverse as far as inlet/outlet - and we changed it and no more poofing ! all smooth starts today.

Hey All,
Just reporting on my JJ1800, it has performed faultlessly since I received it, has nearly 12 hours on it so far, I've only had a few starting problems....which have been caused by me, not turning the gas on, leaving the fuel cock in the off position etc...the engine itself has been flawless and smooth as silk. Makes a decent amount of static thrust too, 19.5lbs @ 115,000 with ambient temps of 30C, so I can't complain at all. A good little engine for the money in my humble opinion. Yes, I service them and am a service rep for JetJoe, but all that aside, the JJ engines are getting better all the time.

As long as the batteries are fully charged and everything else is correct, no problems. I think a lot of the dramas come down to the operator and not the engines, I include myself in that statement.

Cheers and all the best for the new year to everybody.

Smithy.

Imagine
All new JJ1200s, 1400s, 1800s running flawlessly for 25 hours.

Imagine
JetJoe offers a new JJ3600 for less than 2495.00

Imagine
More certified JJ service reps.

Imagine
JJ offers an extended, perhaps lifetime warranty.

Imagine
More JJ users, thus allowing JJ to further reduce their prices.

Imagine
A company working to progress.

Sounds a bit scary[X(], or maybe not to some.

...

...sticky fingers

Imagine
A company STEALING a design and then make a killing selling it for 1/2 price....


Look, money talks. And as long as they make cheap turbines they'll sell. Just don't make innovators or saints out of them.

Erazz, I have copied a BVM Bobcat, Jet 1 A trailing link landing gear, and a whole slew of other things. Does not developing the technology, acquiring the tools, machinery etc. to complete the project reek of innovation? I often wonder what separates me from a company like Jetjoe, is it that I'm not out selling what I make? Look at Dreamworksrc.com and their trailing link gear. Isn't it a copy of Jet1A? Is Todd not an innovator?

I just don't understand guys saying negative things about this company, and then following my advice and short changing BVM on their airline and glues. A company like BVM goes out and spends hundreds of dollars on different glues, then go to the office, spend countless hours seeing which ones make the most sense for what we do, then they repackage the glue under their name. "Aeropoxy".

Then some chump comes on and tells the world that it's Hysol 9462. And the hobbyists bypass BVM and buy the 9462. And how innovative do we feel buying the product direct?

Sheesh. I have no doubt that the guys putting together these engines are trying to put out a good product for a measly pittance. I have machined quite a lot over the past year, and it is not easy, and it takes a lot of time, even when the machine is doing the work.

Well yeah, I guess you're right. It does take a lot of innovation to copy.

I just can't admire them for it.



And as for the measly pittance... Well that's a whole different [link=http://www.sfgate.com/cgi-bin/article.cgi?file=/chronicle/archive/2006/10/15/INGK7LNDJ41.DTL]story[/link] isn't it?

If we are going to split hairs erazz then most of the engines on the market today are NOT an original design and innovation. All engines today are derived from the original KJ66 developed by Jesus and Kurt.
As a point though can you tell me what the Jet Joe 1800 is a 'copy' of please?

There was a company that said the JJ1800 is a copy of their motor.. i just cant remember which. it was mentioned here on RCU one time.

All engines today are not derived from the KJ-66.

I'm not a patent lawyer so I don't really know when it stops being a different design and starts being a copy.

Though todays engines might look the same they are not. There are subtle differences and the manufacturers work hard on improving their design. Each one of them has taken slightly different approaches and solutions according to their way of thinking. JJ is different since he bought the plans for the Wren and simply manufactured it without a license. This is called [link=http://en.wikipedia.org/wiki/Plagiarism]Plagiarism[/link] and it is what sets him apart form other turbine makers IMHO.


I'll say this again. As long as they make cheap engines people will buy. All I'm saying is to not expect me to like it or admire them for it.
