no it is absurd.
Metal main rotor holder they are impossible to find.
Your third site has the main rotor holder but not do you mail to Italy.
I found something in america.
that's why I left everything as it is now.
I only need this but they are not found

I found something in UK, but in backorder - they ship really worldwide -

https://www.hely-shop.co.uk/t-rex-500pro-metal-main-rotor-holder-h50150t/

But UK is not more EU and that will be a problem of taxes, they can be very high -
Thats the problem with "old" helicopters I have also an Align 500X Dominator, there you will get little parts too -

GREAT
idea if i use metal main rotor holder trex 500x ?
all components are the right size same as t rex 500 efl (my t hub)
can you measure me the length of the t hub (the red line)
of your trex 500x
and the circumference measured with the caliper, internal internal (circle red)

Hello Franz,
I measured a length with ~34 mm -
Inner distance between the bladegrips is ~37 mm.

I can now roughly measure the outer diameter of the spacer, which is ~10 mm, since everything is assembled.

I hope this helps !

Regards
Matthias

Vibrations are coming from the tail. It was apparent even from the video sound.
It is well visible from Spectrum Analysis tool. I recommend it highly.

why the vibration are they recorded?
in diagnostic- spectrum analyzer I see them in real time.
but I can fly and then see them?
I know how to use it with the helicopter connected with the usb cable.
But it's not the best to see it on the ground.
My spirit is rs and geolink v2

It is more than enough to record with USB cable at the ground without main blades.
Vibrations come almost always from tail when model is not in good condition.

I did the setup from 0
I decreased the vibrations
now if i use 2500 rpm i have 40% vibration if i use 2600 rpm i have 60-70% vibration.

but I always get the same result
the helicopter flies great
but if i active altitude limit geolink during a flight 3d it activates at the wrong altitude.
If i I fly normal and I don't do any 3D maneuvers altitude limit it always activates at the desired height.

But you have a video of the limit altitude during a 3d flight?
during normal flight (no 3d) if i active limit altitude at 5 metres every time I get to 5 meters altitude limit activates and is PERFECT

but if i use flight 3d and active altitude limit at 5 metres sometimes it activates at 15 meters, other times 10 meters, during 3d flight is unpredictable.
I can see tests during 3d flight?
PS
I also have videos

this is video during 3d flight and when it behaves bad
https://youtu.be/N4jsigR-XAI

this is video during normal flight and when it works well (2 minutes and 42 seconds)
https://youtu.be/RfNbROVy7Us

when it goes straight up it means that it is activated limit altitude
in the first video I tried to change 0 meters and set 5 meters.
In the second video i set 0 meters and i came back again to the hard deck variable
