I just got jetcat from and I run that engine already for about 1 hours with no issue , but now I try to start the engine and nothing happen , after 3 or a attend I remove the engine to get all the fuel accumulate inside the engine , I call jetcat and they tell me to race the acceleration from 100 to 125 , them went I stop the engine , run the motor egain and get what the same problem , and the GSU keep tell me low temperature , everything is ok (battery , Rx battery ) I need some help from the expert

send engine in for check

Mario, if you have already increased the pump start voltage then it's your Battery.

Use a fully charged Li-Po (preferably NOT the JetCat one), make sure is has a High C Rating (35+), and plug this directly into your ECU. For the TEST do NOT go through any I/O Boards or extension cables, just directly into the ECU and try another start.

You may think your ECU battery is good, BUT if it's just slightly down then you will get a WET Start (No Ignition), as the battery has to keep the Kero-Plug HOT, Cycle the Start Valve, and Run the Fuel Pump all at the same time. This can often results in No Ignition should the battery be tired.

Great post, Darryl

I also Agree.

The 140RX is setup for a LifE 9.9v batt. I don't think the old two cell LiPo will work correctly (I may well be wrong here, I just know what the 140 is setup for from the factory).

I had similar problems with mine early on. When I sent it in, Jetcat moved the starter motor closer to the engine, no probs since

Again, not sure if I'm helping or introducing confusion, my apologies if it's the later

Dave

I believe if the starter motor was not engaging or burnt the error code would be "low rpm" and not a low temp code.
Vin...

Darrytarr thank you very much I never increase the pump. Voltage yet , I will do it today and see the result

Vin,

I don't recall the exact code, I do recall that it was something that wasnt intuitive. I could be way off here, I'm sitting in a meeting with the phone under the table right now

Dave

sorry to hear of your trouble.

I am planing on a new 140RX and wondering if any others are having trouble with their new 140rx?

Hope you get it going soon,
Dave

Dave I don't think Mario has upped the voltage yet like JetCat recommended.

I was so busy today there not chance to put my hand in the engine but i will increase the pump voltage tomorow and see the result guys , i hope to fix this problem , but before star this engine i will remove the engine and tested in the test stand one more time , i dont want to get a hot start again , thank you all for your support

Worth checking the voltage the ECU is set up for.

Mike

The voltage setting on the ecu has no effect on the turbine operation.
Vin...

ok guys i try to run the turbine inside the plane 1 more time but this time i increase the pump voltage from 125 to 150 now i am really upset get what the engine never start and a mess of fuel inside , inmediately remove the engine and all the component from the jet , i have no idea what is going on a freaking brand new engine with only 1 hours of run time already giveing me problem

Hi Mario

Out of curiosity, what is the ECU firmware version number?

If you use the ground support unit and test the burner, have a look up the back of the motor and you should see the burner operating nice and bright, it should be at about the 10 o'clock position in relation to the temp probe.<br type="_moz" />

You should be able to hear the Kero lite off as the start sequence is activated. It sounds like the Kero plug is not working.
Vin...

Then why does it have different setting for different batteries?

Mike

yes i hear the Kero lite them just smoke coming out from the motor them the code error (low temperature) and all the connection are ok , no bubble in fuel line all my battery charge , went i try to run the engine i check the GSU and see the battery metter going empty them after 20 secong the engine stop and the GSU say low temperature

Hate to sound like a broken record but have you tried a new battery like Darryl suggested in post #3?

sellery i will try a lipo tomorow , i have a 7.4 volt just came back from hobby shop and try again

Mike, it's only so the ecu knows when to give you a low batt warning. The turbine doesn't care what you set it too.
Vin...

Hi Mario.

I see that you have already increased the Pump Start Voltage. Therefore, If there is still no ignition (or ignition only for a few seconds), with some white smoke, and a pool of fuel, then I can almost guarantee you that your Battery is the cause.

Have a look at the BATTERY symbol on the GSU during the start (it is made up of 4 Bars, or 4 Bricks on top of each other). It should only drop 1 BAR during the start process. If it drops more than 1 BAR then your battery is LOW.

Trust me, plug your fully charged ThunderPower (that you showed me via PM) directly into the ECU and do a start.

You may also want to then reduce your pump start voltage back to where it was before you increased it.

Regards,

Darryl

guys i did everything out my hand and i did exacly what all you guys tell me , today try my engine with a lipo battery and still with the same problem also call jetcat suport and i did evrything they tell me and nothing , still with the same situation , they tell me the engine is cloged and need to send them back to them for service, anyway thank all your guys for your support and i hope the next 2 engine coming on my way does have that tipe of problem.

Vincent, good information. Thanks.
Question: Won't the ECU abort the start up if it thinks the voltage is low because is taught 9.9v and you use a 7.4v ?
