Essyou, megafly is right, if you think the O ring has gone back, you could change them out if you have access to the right part and won't void the warranty, but be careful not to break its supporting post. Most of the fittings of our engines are from Pisco: http://www.pisco.com/index.htm

Good Luck,
Barry

Dale, that sounds about right, if you have the trim low and advance the throttle passed 50%, that actually activates the manual cool down in Kero mode. If something still doesn't seem right, unplug ECU battery and relearn RC.

The Kero Start ECU's are different. They only require you go just above 1/2 throttle for the start sequence. I have the Kero K-140 and it does the same thing at full stick for start up. This is used for manual cool down and to blow out any excess kero in the event of a failed wet start.

Hope this helps

Thanks for the help. I went to full throttle rather than over 1/2. I just wanted to make sure I had it set up properly. My other FADEC ECU's will not run the starter in the ready mode, only at trim low.

So ... would it be a good idea to leave the throttle up for a few seconds on normal startsin order to blow out any residual fumes before pulling it down to initializethe start-up sequence?

I have never found it necessary to do what you suggest. I have always had clean starts.

Just started up a "new" K80E. Actually it is serial no. 108 made in 2009. Has the original Kingtech pump. Fired up the first time and stabilized at 45000 rpm. Flawless. Changed the parameters to the Gaspar settings to see what effect it had. The result was a "softer" start, but a little more flames during the ramp up. Believe it or not, got the engine off of a guy on Ebay for under a grand...N.I.B. Looking forward to mounting it in my Sprint.

Congrats Pedro and thanks for your registration.

Need help!

Went thru 6 plugs tonight trying to get her started!!!

Can someone post stock parameters please!!!!!!

mate set the glow voltage at 2.1 try that if still a problem contact barry at kingtech international
ken
kingtech australia

It is 2.1

Looking for the gas parameters ect...

Looking for the stock settings

Dblex, give me a call tomorrow, need to know which pump you are running in order to guide you with settings, also need to see why you are burning up plugs, could it be how the coils were pulled?

Barry

Barry, seems all is solved. Settings for gas were at 95% and running rich apparently. Got settings from oz and messed with the gas! Actually with Texas heat and humidity, I tuned her down to 35% gas and she fires up first time everytime. I never thought taking it that low would work. I am also using the coleman green bottles for start. As for the plugs, I'm still runnin 2.2 on the plug and that seems to be working.

I have faith in her now and can continue on my build. Thanks to Australia and you guys for your support!

hi Dblex
good to hear your problems are solved

Glad you got it all worked out!

Guys, to reduce the flames using Jet A1 (kerostart) on startup is just lower the Pump Start Ramp value or is there other configuration I can change?
Thanks

Hi guys I need a big help over here, I tried today to star my new k80 but it won't start at around 12.000 rpm the engine puts a lot of flames and gets very hot, I stoped two starts atempts at around 780 degress celssius.
Here's my start parameters.
What do you think?


Pump start point Auto +2
Pump start ramp 002
Glow plug power 7.2v
Low Batt Volts 7.0v
Starter Power at ignition 080
Starter power at fuel ramp 110
RPM 100% starter power 18.000rpm
RPM OFF starter 22.000rpm
RPM to reconnect starter 20.000rpm
RPM ignition 3.000rpm
Pump Ignition 025
Engine min flow 050%
EGT end preheat 120 degrees
RPM preheat 5.000rpm
RPM fuel ramp 10.000 rpm
Preheat fuel 45%
Ignition Timeout 27s
Start mode Auto-Kero

This settings are factory setting, I didn't touch it.

Fuel Pump is MTH

Battery is a Lipo 2s 4.000


Thanks for the help.

2 things to try get a 3 cell life battery and reduce the preheat fuel to 30.

Sergio, Mark is right, you must use a 3S LiFe pack or a 7 cell NiMh, 2S LiPo doesn't have enough voltage. Besides lowering Preheat fuel to 30, you could also lower Min Flow to around 30%.

Good Luck,
Barry

Thanks guys, I've started the engine 3 times with almost no flames, I started with lipo and with life pack and didn't notice anny difference I've changed pump ignition from 25 to 22, engine min flow from 50% to 27% and preheat fel from 45% to 30%, these changes save my day!
Do you know why the factory send this engine with this config?

Thanks again for the help.


Sergio.

Hi Sergio, It's been about one year now since our suggestions to the factory, thank goodness they have finally started to work with us on the settings. As to why this has taken so long? I do not have a good answer.

Regards,
Barry

Megafly,

Just throwing my 2 cents in. On a freshly charged 2S Lipo pack, your K-80 will start fine. When the pack drops to 8V, you will not get the perfect starts and more than likely a no start. If you stay with your 2s Lipo pack, "CHECK THE VOLTAGE" if you have a no start. Don't mess with the settings, as you now know what settings work best on your turbine. I would take Barrys advise and go with a 3S LIFE or a 7C nimh pack as they tend to last longer through out the day of flying. As for you guys running the Kingtech propane start E model turbine, the 2S Lipo works fine.

Good Flying,

Concerning checking voltage, please press the second button from the left during start up for real time under load voltage.

Thank you,
Barry

This is a fact. I have a propane start on a 2s 5000 mah pack, and I can tell you she is good for 3 starts, after that if she drops voltage or a cell is slightly out of balanced, she will not start. You better have a good charger and balancer!

Had a strange problem with two Kingtech K80s that are installed in falcon 120s.   Last year, at around the same time we had two K80's that would not run cleanly through out the throttle range and would flame out for no apparent reason.   It was around 32 deg. C for temperature and a 100% humidity as we had rain showers and thunder storms all day.....  we sent the engines back to the factory but the factory said there was no problems and the engines were good...  they have been running well and on my unit,  i have over 12 hours of uninterrupted flight time.  <div>
</div><div>Similarly...  around 2 days ago, similar conditions (32 deg. C and 100% humidity, showers with some thunderstorms)  for the K80's existed and again, the two engines wouldnt run clean through the throttle range....  after you had achieved start up and the engine was running, sudden acceleration to 50% power would result in a flame out....  over and over again...  fuel system, fuel was clean.  no contamination....  all valves worked, fuel purge was no problem, filters, UAT were all clean......  </div><div>
</div><div>we then did a longer ground runup and slowly opened the throttles allowing the engines to adjust slowly to each throttle setting...  there was a bit of choking at 50% throttle, but if you allowed the engines to adjust slowly at each throttle position, until WOT, the engines eventually were able to adjust and did not flame out anymore...  seemed the engines had to warm up at first????  </div><div>
</div><div>I'm not really sure "warm-ups" are necessary but it has got me thinking that the ECU may have an issue with High Humidity environments?  thats the only thing i can think of as both K80's had the same problem.....  Would sealing the ECU be a good solution?  Anyone had similar occurrences?  </div><div>
</div><div>Thanks in advance!  </div>
