Default FEJ Liberty-S thread..

Well... my Liberty-S is on the way to Europe.

All James mailed me was a glimpse in the box before they shipped it..
This is the first "S" FEJ has done in the "HPAT" color scheme.



What i have so far are the settings suggested by Keith (aka Jetmodeller)
C/G at 20mm not 30mm ((The [link=http://www.flyeaglejet.com/en/Liberty%20Instruction%20%20Manuals.html]MANUAL[/link] however is saying 300mm))
Ailerons 10mm each way
Elevator 15mm each way
Flaps 45mm total movement

I would like to use this thread for sharing Liberty-S experiences.
So for all you Liberty-S owners out there, lets share..

Yeah she does look good doesn't she?!

I am going to mount a Jets-Munt Merlin 90 Turbine.
Should be plenty of blow for this bird.

The HPAT color scheme has only been done on the Liberty-L .... till now

(THIS IS THE LIBERTY-L)

I will keep you posted as soon as she arrives..
(maybe an unboxing on YouTube would be an idea)

Measuring from the wing root does make it easier to ballance.
Thanks for clearing this with us Keith.

I am subscribing to the R C J I magazine as we speak.
My only hope is that i will still recieve issue 100 !!

Very curious what you wrote for us Keith.


Thanks,

Hey guys ,
This airplane looks Firebird-ish especially the air inlets etc.
Anybody flown one yet , whats the performance like ?
I know the new RCJI has reviewed the kit but the review didnt sound terribly exciting.
Can it take a 120 ?

Yes, she does have some Firebird resembleses..



The smaller liberty-S can hold up to 92mm Turbine diameter.
The bigger Liberty-L certainly works with a 120 - 160 Turbine.

I think Keith is the most experienced Liberty-S guy who can tell you more on how she flies.
Like I said, i am waiting for mine to arrive.

As soon as she's in, I will update this thread with my build and flight experiences on this jet. (with YouTube videos to support it)

Actually, to see a Liberty and a Firebird side by side, they don't look as similar as one thinks.

Hello Bob,
This particular Liberty-S is powered by a Wren Super Sport.
A jets-Munt merlin 90 would also do the trick.

Note the NACA ducts on the top and bottom, these ducts gave the Wren 10N of extra thrust.

It had to do with a wheel being a little stuck in the wheel well and a small air leak in one of the hoses.
The problem is fixed and Bert van Didden will fly the Liberty again this upcoming week-end in Nederweert the netherlands.

Appart from that, the gear and cilinders are fine.

Let's keep it on-topic please?

Cool vid and nice flight.

Behaves very well and very fast!!!! I like it!

It took me 12 months to sort my air lines and cylinders for leaks. Now works perfect every time. Called teathing problems and is normal.

The Liberty S and K80 combo Ill be using also. I would think any 12-18 lb thrust turbine will be just fine.... I also have the Liberty L in the works and plan to drop a Kingtech K160 into that one.

Hi guys

Iv been flying the liberty L for awhile now and it is realy a awesom jets,it is very smooth and has no bad habbits.
It does take alot of set up to get flying 100%,the set up is very critical just like a good pattern plane.
We had the South African jet masters a few weeks back whivh i won with the liberty,the only thing i would suggest is setting up a little crow brakeDue to the very little frontal drag
she tends to come in a slightly hot.However i do fly at hight altitude and off a normal model field you cant take to much of a chance on landing,you need to get the speed right and get her on the numbers.

Regards Greg

Hi JET FX,

Will the Kingtech K80 fit in a Liberty S? I thought the the diameter was too big.

Without modding the airplane, a 92mm Turbine is the absolute maximum, you can fit.
A K-80 will eventually fit but you need to remove some wood of the turbine mount in the airframe.

If you do not have an engine yet, a Jets-Munt Merlin 90 is the engine to go for.
95 Newton of power and only 90mm wide.

Hi Craig, I have not trial fitted it as yet although I dont see there being any issues fitting the K80, maybe at best a little triming of bearers and she should be fine. Feel free to email or PM me your contact details and I will send you some pics of my K80/ Liberty install...

Cheers- Marty
