P-200SX
 

A new P-200 SX has been announced at the JetPower fair by Jetcat.
It has a new compressor ( CNC machined ), a new combustion chamber and internal kero start.
The engine will also come with up-rated power cables to match the peak current draw during the start sequence.

I will receive a unit for test and review soon and will keep you updated...

That's an awesome news! Thanks for sharing.<div>

RE: P-200SX
 

Is there a power increase??
V..

RE: P-200SX
 

Yes. The turbine is rated at 230 N from stock instead of 220 N on the German web site. That is a 5% increase.

RE: P-200SX
 

According to my calculations thats about 51.7 pounds coming out the tail end. Thats a lot of power. How much better will the spool up time be on the SX? Price and availibility?

RE: P-200SX
 

When are these shipping in the US?

RE: P-200SX
 

Well the regular P200 can be set to 52 lbs now if I am not mistaken. Can the new P200SX be set to more than 52 lbs of thrust.
Just wondering ????. I need more power he he...

RE: P-200SX
 

You are right Eddie.
Both engines share the same aero dynamic design.
The 200SX being stronger, can be pushed systemically to 52 lbs from factory.

The acceleration time should be the same: 3 seconds from idle to full RPM.
I haven't put the SX on the bench yet ( I need a stronger bench ... )

RE: P-200SX
 

go on my friend...

RE: P-200SX
 

Oliver.
I am quoting you from the FEJ F-16 thread.

Got my new P200 SX the other day:D

One thing I don't understand since the P-200/SX is so thirsty and have high demands of the plumbing and fuel system, is why they supply the P200 with a Hausl fuelpump with the small 4mm intake nipple?? Had a look at my friends older P200 and it had the small pump too...
Even my Merlin 160 is delivered with the ZP30020SF pump with 5mm intake nipple. Why don't JetCat use a pump with 5mm intake nipple to prevent cavitation??

Quote from the MTH web page from the ZF30025S/F pump: "5mm suck fitting for a lower suck resistance. (cavitation)"

Have a look at the [link=http://www.modelltechnik.at/E300.htm]MTH pump web site[/link]

RE: P-200SX
 

why dont you ask them directly?
anyway we are running 4 or 5 engines at the moment , no problems so far even with our own UAT...
we go from uat to pump with 6mm festo , just before the pump we change to 4mm.
also noticed the pump runs about 5.8 volts on full power , so it does deliver what they say..

RE: P-200SX
 

Hey Staale,

I have the NEW P-200SX (Serial Number 659) and also have one of the last versions of the old P-200's (Serial Number 568).

I am using 5mm Polyurethane Tubing from the Header Tank (JMP Machined Aluminum Accumulator) to the fuel pump. To make the 5mm tubing fit onto the intake nipple I use a small piece of 4mm tubing then force the 5mm over it and use safety locking wire.

I had originally used the BVM UAT but noticed it collapsed considerably under full power due to the high fuel flow and this caused fluctuations in the power management throughout the throttle curve. I then changed to the JMP one and its perfect for this size turbine. In fact the quality of the JMP Accumulator is outstanding.

Dont get me wrong, the BVM UAT is a great product but I personally wouldn't use it for turbines bigger than 160 size.

Buy the way the P-200SX is superb and will easily do 230 Newtons at 112K (51.75 Lbs).

I hope this helps.

Hi Darryl
Long time no speak. I hope all is well with you?
What sort of fuel load do you think we should be looking at carrying to get a respectable flight time with the 200 SX?
Regards Al

RE: P-200SX
 

Hey Ali,

Good to hear from you, how are things your end?

I am using the P-200SX in my Skygate Hawk and have the standard 4 litre tank PLUS two BVM MiG-15 Saddle Tanks (0.75 Each). This gives me 5.5 litres. I fly comfortably for 9 minutes and the GSU consistently says that I have used approximately 4 litres (never more than this).

I was using the standard P-200 before and fuel flow was exactly the same.

Hope to see you in Al-Ain and Dubai soon for all our upcoming RC events.

Regards,

Darryl

RE: P-200SX
 

All good at this end thanks. I have a couple of models that the 200 Sx's are going to find their way into. Tomahawk hawk ( Sightly bigger version of the skygate Hawk ) The HT Modellbau Hunter, and a Skygate Hawk that we are building for a customer ( from your neck of the woods :eek:) and trying to work out of 5.5L will be enough?

Thanks for the feedback.


Regards Al

RE: P-200SX
 

So potentially no need to change the 5.2L tank for the TomaHawk for an 8minute flight.

Al, you got a 200SX in for me yet? ;)

Cheers,
Mark

RE: P-200SX
 

MMmm that sounds good.
I am still finding it hard to believe that 5.2 ill be enough! I might still fit a bit more just to be safe ,
Oops forgot about your 200 Sx mate LOL I never thought that such a monster of a turbine would be so popular! With your order and other customer orders put together it means In total I need to order 8 of these bad boys! God bless big jets LOL I just hope there are enough left for me :eek:
Regards Al

RE: P-200SX
 

Hi Ali,
Don't listen to Darryl.
You'll need 20 liters of pure nitromethane to make the most of your 200SX ;)

RE: P-200SX
 

Who is them? JetCat Germany? It is my experience that they are not not to keen answering any questions and especially not in English...

I ask the question here because there seem to be a lot of dealers, reps and even a turbine reviewer that read this forum. You as a JetCat dealer and with your own brand of turbines (still?) may be able to answer why JetCat want to use a pump that the manufacturer recomends for up to 150N turbine on a 230N one??
The pump is rated 500 ml/min at 6V and at 6bar/ 85 psi pressure which means that it will deliver much more if the pressure is lower.

Anyone got an idea?

RE: P-200SX
 

Hi SAP,

I know that the pump nipple looks small but the plumbing that Darryl has described earlier works.

The answer to your question is in fact simple. They chose to keep this pump on the P-200 because it works !
It makes things much simpler and cheaper: one type of pump for the whole engine range.

The P-200 goes to 6V at full thrust.

RE: P-200SX
 

Thanks for answering, Oliver.

Thats what I thought. They want to keep things simple, allthough I don't think it would kill them to use two types of pumps on the thousands of engines they sell:D

Then a theoretical question.
I happend to have a couple of NIB ZP30020SF pumps with the big nipple (!) lying around. In your opinion would that pump work on the 200 given that you adjust the pump start and ramp values if needed and take it up to full rpm slowly to learn max pump voltage?

Loking forward to your review[8D]

RE: P-200SX
 

they want to keep things simple,one type pump for everything very smart.
i do agree it is running at its max , but then with 3 years warranty...it does not really matter it works.
you can ask Max Rheinhard very helpfull person and always giving a answer.
about using a more powerfull pump , you would need to change all the value,s inside the ecu , not possible.
it is not just a matter of setting the lower pump start values the whole range must be changed..
since the changed to the new SE-SX engines not possible anymore.
the idea behind the concept they use is that you can swap every engine between models without changing anything.
the ECU will find out what engine is hooked and will set all value,s automaticly.
all our sold SX 200 run fine , and at their max speed ..
so enjoy the engine and dont tamper with it ;).

RE: P-200SX
 

Amused people worry about the pump when they use Festo connectors and std JetCat filter with small holes in. We open up JetCat filters for all P160 plus set ups and either avoid Festo connectors or open them out.

std and M&R opened filter case.
