Hello.
Don't understand why X16 Mlink flickers a lot with many lost frames. Doesn't matter if I use Mpx Mlink or Radimaster Boxer and their ER receivers.
How should I interpret the LF values that count at a fast rate, what is acceptable? Is there anything I can do to make the green light shine with a steady light and avoid all lost frames?
My X10+ behaves the same. Otherwise, everything works as it should, all the servos move smoothly and well.

What input mode are you using? You should never see any flickering unless there is a loss of data. Do you have receiver ports enabled without a receiver plugged into the port?

With Multiplex and RX-9-DR rx on X10 I use 6 FLASHES 6 – JETI UDI/MPX SRXL.
With Multiplex and RX-9-DR rx on X16 I use Multiplex SRXL.
With RM Boxer and ER6 rx on X10 and X16 I use SBUS.
To your question, "Do you have receiver ports enabled without a receiver plugged into the port?" I'm not sure which way I used, maybe tried both with and without connected receiver?
Have you seen my video? If not here is the link,

Would be grateful if you answered how many lost frames is acceptable.

You should never be seeing continuous lost frames like that. Do you happen to know what frame the Multiplex is using?
Do you see the same thing when using SBUS?

I have set 14 ms with Multiplex (fast respons of), all according to the manual for X10+. When I use Boxer and ER receiver (elrs) with Sbus both in X10+ and X16 it behaves the same.

Although X10+ and X16 count LF very much, they never goes into failsafe and everything seems to work, but I dare not fly with the system when it behaves like that.

Problem solved with Multiplex, I had the wrong modulation/frame rate 21 ms, changed to 14 ms and everything is perfect. Now I have to try to find a corresponding solution with Boxer and the ER receivers, which are ELRS. Will report back if I find the solution.

Which LF values are recommended or acceptable? In the last test with Boxer and the ER receiver (elrs), the X16 registered 5-10 lost frames within 1 minute, is that ok?

I tested the X10+V2 powerbox again with the Boxer tx and ER6 rx with the same settings as with the X16, D250-104dBm, telemetry ratio 1:32 in Wide mode. I guess I lost no frames, or only those 5-10 lost frames per minute so hope/believe I must be satisfied.
You can see in the video that the green LED lights up steadily and does not flicker which it did in previous test.
And the result was the same with X16.

5-10 per minute is perfectly acceptable. You can actually safely fly with 80% packet loss. Sounds like you found the solution!
Keep in mind that you are more likely to be seeing lost frames inside your house than outside your house, or at a flying field. You will likely find that turning on your microwave oven in your house causes a lot of lost frames compared to normal.
