Default JetCat P-130RX

JetCat showed a prototype of the new P-130RX turbine at the 20th Anniversary weekend. They also flew one in a Wild Hornet.
This is almost the same diameter as the P-100Rx (99mm), but longer at 284mm. It's a great option for a lot of aircraft, it only weighs 1350g
Pump is external RX type, but single wire/single fuel feed.
Testing is still in the early days, but it should be available before Xmas.

Shown with a P-80SE

The first batch of P-130Rx have been shipped and I received a few this morning.
This is the first turbine with the new V12.0 ECU which has even more features than the amazing V 10 series. Telemetry functions are now available directly.
An interesting point I had missed is the turbine is supplied without an ECU battery for the first time with JetCat, 3s Li-Fe or 2s Li-Po batteries can be used-this suits me as most of my customers use a 2s Li-Po and usually larger capacity than the old 2100 Li-Fe that was supplied.

More details here.
The P130-RX turbine features JetCatís new V12.0 ECU with telemetry functions. The fuel valves are complete integrated in the turbine housing. It is only a single tube connection from the pump to the turbine. The turbine is electrically connected to the ECU via a single PowerBus connection cable. In addition to the supply battery and the connection to the receiver (1 or 2 channels), the ECU only has to have the fuel pump connected. The power supply is preferably a 3S / 2100mAh LiFePo4 battery. Alternatively, the ECU V12.0 can be powered with a 2S LiPo. This not only provides the ECU and the fuel pump with power, but also all optional components connectable to the bus system, e.g. an additional pump for Smoke and / or LCU (lighting control). Connecting another bus pump, this can be configured as a smoker pump. The setting of the smoker pump power then takes place directly from the ECU. The ECU V12.0 has an integrated precise air pressure and temperature sensor, through which the turbine control intelligently adjusts to the current environmental conditions. The ECU V12.0 also has an internal telemetry adapter.

The internal temperature sensor keeps the outside clean, but can be easily exchanged by the user. Like all SX/RX turbines the engine starts with kerosene.

Hey Dave, thanks for the info.

Potentially dumb question... Have they changed their RPM sensing scheme away from the old trusted ring magnet in the compressor nut? There are a few features machined in the inlet that I don't recognize.

Thx,
Kelly W

Pretty certain it's still a magnet in the nut.

Maybe holes for cooling systems under purple cover..... in the car turbocharger you can find holes for eliminate surging compressor issue

Reviving an old-ish thread.

Are any of these engines in the hands of customers and flying? Curious if there are any reviews on it from 1st adopters.

Thx,
KW

Has beers and dinner with the Jet guys. Less than 24 hrs later - looking for engines on RCU. LOL

Cheers,

It’s winter here, but on the Xcalibur Plus thread one of my customers is flying one. RCJI have done the test for the next issue.

Got 1 hour on the engine now flying my Xcalibur Plus and it's working great. More than ample power for my style of flying and I have been impressed with the no-fuss starts, even in some of the coldest weather this winter. Had it landing slower than the Wot4's today in nil wind with the low idle thrust and big wing! Very pleased with it so far.

That great to hear Mick. I'm itching to put one of these in a Boomerang Elan, needing some extra push to get of a short-ish grass strip. Its has a P70 and it just barely does the job.

My only issue concern is a past experience of getting a new engine design that is said to be perfect, only to have multiple recalls, serial number ranges to be aware of, etc. I hope this one works out.

Hopefully as the weather warms up we'll here a few more success stories.

This engine will certainly 'wake-up' the Elan Kelly!

Someone always has to be one of the first, this is my third JetCat. We fly off a 100m strip of grass which at this time of year is rough and a little bumpy. At present I am the only guy flying jets, for years a myth perpetuated in the club that our field was unsuitable. Almost 20 years ago people tried and failed, with what I would call first generation models....heavy, high wing loading, small wheels and underpowered. Some of the older modellers even insisted retracts would be ripped out on the first flight and should be avoided at all cost. Well my large warbird Electrons have done hundreds of cycles and are still going strong so that idea is consigned to the bin! It is amusing to see their faces as both the standard and plus Xcaliburs take off and land in less than half the strip. The effect of this has been a renewed interest in what is now possible, we now have a guy building up courage to fly his first turbine (P80-SE Elan), and another retired chap building his first jet at 65!

I am about ready to start it up in my T-38:

The Skymaster Northrop T-38 Talon Project of 2019

I assume it programs as earlier models. The box was the first from Dreamworks and it has only a v10 version manual supplied. I would like an English version manual for the v12 ECU. Anybody have a link for this?

Do a learn RC, prime the fuse line to the turbine and go, just like the V10. It’s just the telemetry added to the V12

How does one use the telemetry with a DX18 transmitter?

All I can say is the direct connection cable would not work with Jeti as the sensor list is not populated on switch-on. No biggie, just used the JC telemetry adaptor with the ribbon cable and all is well. You may have more success with Spektrum! Interestingly, if I configure initially with the adaptor and then connect directly it will read the data stream, until the next power off/on cycle.

If you're asking how to hook it up you'll need the Jetcat telemetry adapter that plugs into the ECU, then is depends which receiver you have. If its one of the newer telemetry enabled RX then you plug the adapter directly into the RX, if it's one the older RX then you need to get a TM100 module that goes between the adapter and the RX.

After losing a jet to a flameout that I didn't know happened till it was too late (at jet meet with 6 other planes in the air) I don't fly a turbine without telemetry anymore. If nothing else it'll let you know within a second of a flame out, already saved one plane with it.

Along with a few others here I'm sure - I was hoping to hear the integrated telemetry function would not need the adapter to work with a spektrum RX. Not the end of the world, but its just more equipment and connections if this is the case.

That drives the question. What radio brand(s) does the integrated telemetry work with, and is that the 3-wire lead matching the 'T' port?

Thx,
Kelly
