Hi All, if you have a K-210 with ZP30025S pump, please do some ground tests before taking it to the air, as we've been having a number of flame-outs caused by the tightness of the fuel pump.

The test you want to do is to get a reading of the idle pump pw, anything over 55 may be a cause for concern. Another is having the engine at half throttle and pull back to idle. Some tighter pumps will cause the engine to shut down, and we have since then outfitted our 210s with the ZP30020SF.

We apologize to those who had flame outs due to this problem, while thanking them for working with us to help us get this problem resolved.

Regards,
Barry

I have encountered problems with mine on start-up during the ignition to pre-heat phase switchover where by the default setting of pump power @ ignition setting of "20" was not enough especially first start of the day. The flame would go out on ignition phase as not enough fuel was being pumped. Email to Kingtech Australia and subsequent advice from Factory was to increase the pump power. Setting is now @ "25" and all is good. Will monitor pump power at idle and attempt to replicate the problem listed above.

The other model pump then has enough flow to keep up with the 210's requirements then?

#27, the adjustment of ignition pump pw from 20 to 25 may be an indication, well within the tolerance, if you don't have flame outs I wouldn't worry about it.
Yes, the ZP30020SF pump is an excellent fuel pump with great reliability, as we are using only up to 40% of its capacity.

Forgot to mention what to do next, if you have determined that the pump may be tight. As long as you have registered your engine, please contact us at [email protected] and Vera will send out the ZP30020SF pump to you with a return envelope.

Hey Barry, will the K180G have the same problems? I have one, but still in its box.

Cheers

Not at all Matt, in fact, the ZP30020SF pump is a 180 pump, now 180/210 pump.

what a great stand up guy!!

marquisvns

Thank you Rapptor, but we are actually a little short on replacement pumps at this moment, more pumps are coming in this way, if you feel you have a pump that needs to be swapped out, please send us an email and make sure you have your engine registered. The next batch of pumps will be arriving in a week or so and will be shipped out on a first come first serve basis.

Thank you for your patience and working with us,

We've just received the new batch of ZP30020SF replacement pumps, those who are in need of swapping out, please contact us and be ready to send in the ZP30025SF pump.

Thanks,
Barry

Barry,

Are you recommending all k-210 owners to change the pump? New k-210 won't come with zp30025s anymore?

I have a brand new k-210 and I'm concerned. Should I change? Would you say if Im below 55 on idle Im good for sure? What percentage of pumps are having problem? If I dont change the pump should I staying monitoring idle frequently to see if my unit become defective or it should appear as brand new?

Sorry for all these question.

Best,

Gabriel

marquisvns

Those are very good questions Gabriel; the percentage of 30025 pump issue is between 5 to 10% percent. With idle pw under 55, I would say you are good, unless if you are going to be installing it in a F-104, I'd say let's change it out. Once it idle well, it should be good from that point on, if the idle becomes high or rough, and irreversible with RC relearn, then contact us for the swapping out.

Barry

Barry,

I'm installing it on a 44 lbs BVM F-100. Better to change. Do you agree?

Best,

Gabriel

Gabriel, It's all up to you, as I'd be happy to accommodate, just let me know through email, and if you could register your engine would be great http://kingtechturbines.com/doc/registration/form.php

Barry,

I spoke with Kingtech Brazil and I will get a replacement pump from them even having acquired my turbine from Kingtech US. Great service from kingtech US and Brazil.

Thank you very much.

You are welcome Gabriel!

Barry,

I think I will take you up on your advice. My 210 is still new in the box waiting to go into a F-104, so I will speak to Ken down here to organise a replacement pump.

Thank you for letting us all know.

Cheers,

Jan

Barry, I brought one from Dreamworks on February and came directly from factory, it is still on box and I did the registration process.

Does all 210 engines came with the defective pump? I'm about to put it on the bench to fire up but, I don't know if is better to ask for a pump replacement.

What are you suggestions?

Thanks
Osvaldo

marquisvns

No problem Jan!

Osvaldo, a good number of the ZP30025SF pumps are running fine, but if you are more comfortable changing it out, I'd be happy to arrange, being in outside of the US, we're going to trouble you to send it in first, and make sure you are registered with us. Otherwise, you are welcome to follow my opening post to test the pw during idle and decide then.

Also to note, our replacement pumps are out again today, and shipment should be in towards the end of next week from MTH of Austria.

Best Regards,
Barry Hou
