Hi Prahlad,
Here are the start point settings for the 3000.
Set you ECU and let us know.

Full power speed 115.000 rpm
Idle speed 32.000 rpm
Stop speed 20.000 rpm
Acceldration Delay 020
Deceleration Delay 015
Stability Delay 043
pump start point auto +2
pump start ramp 002
Glow plug power 038

The 1800 and 3000 use identical ECU settings. If you have verified that the same pump, harness and ECU work with your 1800 then there may be in issue with your turbine running just on propane. Please PM me and I will help you to trouble shoot this step by step.

I have the same settings on my engine but just hangs and goes into over temp" it's a DIY engine that I have assembled as per instructions...

Probably the preload need to be set.
Talk to Andy, I'm sure he will sort it up easy…

If all the parameters are exactly the same as the JJ1800 and it just sits at 16000 Rpm,it could be a preload fault? Sounds like it starts over fuelling and hasn`t got the rotor speed to reach self- sustain Rpm. Try to decrease the pump ramp value and when it reaches 16000 Rpm,disconnect the starter wire.(It could be the starter that is "holding" it back). I experienced this before and the cause of this,was the starter. If you can set the ECU for a manual start,then do so. By doing this,you can get the engine to run and the ECU will "learn" the parameters. Then you set the ECU for auto-start and it should be sorted out?

I really believe that you are not getting enough rotor Rpm,during the start-up process. Also ensure that you have a fully charged battery and enough maH rating too.

good luck with yours, mine has a couple hot spots on the nozzle which I believe is poor fuel needle soldering or inaccurate needle nozzle ends creating a lean condition at the suspect needles. ran it the other day and the temps were good 590c at max thrust but the thrust only measured 26lbs. the probe of the thermocouple is not at the location of the temp problems. ngv looks to be a orange red color say around 1400 f. I really don't want to put more money into this but the balance seems real good. it seems to do all the proper cycles to run fine. Blake K

Hi Andy could you give a idea about mine, I sent you a couple email about but got no replies, might went to spam.

Hi all,

I just managed to get the jj3000 running but the problem was that the starter was not spooling up the engine sufficiently so as it was hanging I disconnected the starter from the ECU and connected a batt directly to the starter and it started ramping up and soon was self sustaining and the temp came down to 660 and then ran well.....

any suggestions for this problem.....

Prhlad,

As I said in my PM, this sounds like starter alignment so we have to rule that out before going any further. It is a good possibiilty. I do recommend to remove the starter and air start the turbine. After 17k the motor is on its own. If it hangs with air and no starter then we may be looking at a similar issue that I helped Snir with but simple things first.

Hi Blake,

I did respond to your PM. I am not sure with your engine without more info. Did your turbine run for a while and then get like this? how much time on it? The needles could be clogged but the gauge size of the 3000 and the 1800 is sufficient that I dont see clogging too often, but that is not to say that is not what yours is doing.

Call me.. I left you my phone number.

I want to thank Andy for his help with my JJ 3000, I have a video up on you tube search "blake's jetjoe 3000 running " the 2 hotspots were not of real concern. fine running turbine got it used for a grand with less than 2.5 hours on it. did have to replace the thermocouple. probably why the guy sold it. I am putting it in a used fei bao rafale and should get it all together for 3G's

Hi knobby,

i want ant to know if you have any idea why I am getting a flame from the exhaust of my jj3000 when AT idle,I can understand while start up but after that...

any ideas please let me know

Looking for some help. I accidentally threw the Restrictor for the fuel/oil feed for the bearings. Does anyone know what I can use in place of the piece that was there?

0,6mm siringe needle

cut the big plastic part.. then remain diameter to fit in festo tube
put little filter before to prevent needle occlusion

Looking for some help mounting a new starter & bullet housing to my JJ1400. I purchased a new aluminum cover, and it isn't drilled so the starter can be mounted. I can certainly drill the holes, but from the looks of things, and some experimentation the "legs" on the new bullet are so long that the Bendix won't engage the compressor nut. I know the starter is supposed to be "adjustable" in the housing, but even when the cap on the bullet is tightened all the way the starter is still a little loose so I wrapped it in some Teflon tape to make it snug. I've thought about cutting the legs, but I'm afraid that if I don't get them exactly equal in length that the starter housing won't sit true to the compressor nut causing misalignment during starting. Also, by cutting the legs, they would now sit down inside the aluminum cover, on the angled portion instead of on the front edge. Again, I would be afraid of getting all the holes drilled perfectly plus, I have no idea how I would ever get a driver on the bolt to tighten it. Any help would be great.

Hi.maybe you can play with your starter motor shaft,what is your motor shaft lenght??
It is a speed 400 6v motor?

Xairflyer

My Feedback: (1)

Dont cut legs, it is a fiddly job to get aligned but should be correct length, just asking, you do know in use the bendix extracts (gets longer and so engaging the spinner nut when spun) ?

Dura Flame

Yes, I know the bendix extends when spun. I checked the engagement with the bendix extended, and it would not engage the compressor nut. I am running the stock starter motor with the bendix attached to the shafts at the stock length, pushed as far forward in the bullet housing as I can get it.

Dura Flame

Can someone verify the length of the stock legs (mm)?

I am trying to reach Andy Fioretti. I have emailed and left a couple of messages. Does anyone know if there is a better way to get in contact with him?

Hi everyone,

I recently bought a 1400 and got it running for a short time. However, I shut it down quickly when I noticed a lot of fuel leaking from the joint under the intake. Could this be an issue with priming the fuel too far in the system? I had a few accidents whilst getting used to the startup sequence whereby I accidentally started the priming sequence and caused the fuel pipe to pop out of the inlet but this did not lead to a 'fiery' start.

Thanks in advance for any help.

Dura Flame

It could be several things. I had an issue on mine with the nipple that is braised to the fuel line that supplies fuel to the combustion chamber coming loose. The would cause fuel to leak out of the fitting and run out of the intake. If you (or someone you know) can braise a small fitting, it's a simple fix. Excessive priming could be an issue as well however this usually leads to a hot start with a flame show out the tail pipe. Good luck.
