Hi Rush, seems like there maybe a combination of problems, fuel pump becoming more powerful plus the adverse condition of high humidity. All you have to do is to put the acceleration delay higher in the RUN menu for a smooth acceleration.

HI Barry,  i did....  My acceleration delay is normally at 5.  I adjusted the delay to 10 and it still quit... Should i have gone to a higher value?   I eventually returned the value to 5 and then just did longer ground runs prior to take off...   

the next day we had bright sunny conditions and the engine was good 1st time i tried it....   what do you think?

nyahh...  I dont fly in the rain.  Just tropical conditions  

I'll see if i can wrap/seal the ECU in something...  just wondering if anyone has had the same problem elsewhere in the world and what they did, if anything to fix it.

Barry,
I'm putting the K-80F in a Boomerang Elan; any guidance on how far the exhaust tailcone should be from the end of the exhaust housing on the Elan? I searched the Elan thread and it doesn't look like anyone there has installed the K-80 in the Elan.
Regards,
Gus

I mounted mine about two inches back from the rear edge of the shroud. So far, no burns or scorch marks on the fuse.

Thanks - I appreciate the pics! How does it fly with the K-80? I'm at 6500 feet msl here, but I think it will be okay.

Gus

No problems with the K80. Starts everytime and runs great. More than enough power for the Elan (at least at my altitude - Mississippi is less than 500 ft msl at most points).

Maidened the Elan last Wednesday and now have 10 flights. I spend a lot of time at 3/4 throttle and above here atalmost 7,000'. Could use some more thrust, but it's okay. Sure does fly nicely!

Gus

Hi Rush

Lately we have had 3 K80's doing the same thing. All quiting at around 60 000 rpm. Hi ambient around 30 deg C and fairly high humidity and 5000ft ABSL.

We have not solved the problem. We sent the motor to a KingTech rep here who tested it at 900 ft ABSL without problems. We tried all settings on the ECU without any issues. Motors ran fine during the winter. Have sent the one back to KingTech and will see what they say?

I am putting my K80 in a F-16 and this will be the first time I have run my K80 with a pipe, I currently have it mounted with about 3/4" separation between the mouth of the pipe and the tip of the Turbine... is that correct? See pictures and I appreciate any feedback

Barry may want to weigh in here, but I had about 3/4" from exhaust to bellmouth on my F-86 with no issues. If you look on page 38 of the new (updated Jan 2013) manuals (http://www.kingtechturbines.com/doc/manual.pdf) you will see that they recommend 20-30 mm (.8 to 1.2 "), so you are probably okay.

Gus

Thanks for bring it up Gus, but the dimensions from the manual is only a reference. b has over 5/8" from the bell mouth and I would say it should be just fine. I have seen 1/2" being cooler running, but perhaps has to do with the design of the pipe. Basically, once set up, you wanna run it on the ground at full throttle and take a look at the temperature. If it doesn't over temp on the ground, it would only get cooler in the air.

Barry

Hi Jet Doctor, as of now, we (both Taiwan and US) have not received any engine or tracking notifications from South Africa, please advise, as we look forward of sorting this out.

Barry

Hi Barry

Thanks for the offer. As it is not my motor, I do not have the exact detail but I will find out about it for you. It might have got a lift to Nuremberg and taken from there?

No thanks dr., not interested in hearsay, especially technical troubleshooting requires precise information down to the minutest details, please have the owner contact his dealer and or myself, thank you.

Hello, guys, I'm an experienced RC flyer, 25 years scale building plus. Considering making the leap into turbines, and would like some quick feedback on the K80E from Kingtech. What's the consensus? Is this platform reliable? My elevation is 900ft MSL.

Not sure what else can be said of the Kingtech products if you review this K-80 thread and the K-140 thread elsewhere on RCU. Owners are reporting great power, superb reliability and great service from Barry. I have the K-140G, have ran it not flown it yet. Have the K-80F (kero start - why would you get the K-80E?) and have about 30 flights on it now at 6500' MSL with no issues. I may try to tweak it a bit next summer to improve the starts (cut down on flames on start), but other than that, just put kero or diesel in and go fly.
Regards,
Gus

Very reliable. I've had more than a half dozen k80's, 140,s 170,s and flown 100,s and 180,s, from the first propain start design to the latest kero start with internal valves. Throttle responce is fantastic, One of the festest on the market. The factory is always improving on design, All service is done here in socal and the turn around time is very fast. Sales and service are untouchable, Barry and Dirk are the best!

I've put all the Kingtech turbunes through the paces and they are solid. I'm not just saying this because I'm a factory Kingtech pilot, Solid engine, solid service great market price and true performance!!!!! Ohh did I mention diesel. No more chasing Kero down at the local hardware store.

I have many friends that made the switch from brand X to Kingtech and love em.

OK I'm done. Lol

Got a mate running them and you are right they are a fantastic product the only problem I see is they wear out airframes.

Guys, Thanks very much for your helpful comments on the kingtech turbine!
I mistakenly wrote 80E, But I meant the F version.
Please don't think I'm not reading this entire thread, I am.
It's just that reading how people resolve their various technical issues Isn't the same as asking them to sum it all up.

Does anyone know if the FOD screen For the 80E also fits the 80F?

Also, has anyone heard anything bad about the F86 Sabrejet from Modelbau on Troy built models website? The nose looks a little funny but the price is right. Thanks.

I have both a k80 and modelbau f-86...


I Love the k80, would do another in a heartbeat....

As for the f-86, the price point is great but be prepared for some work! it is not a typical ARF so you will need to go through it pretty good! For me, I got burned out on all fixes and upgrades on the f-86 so I ended up putting the 86 to the side and need to get back going on it and try and Finnish it up or find someone who wants a f-86 that is glassed in primer
