I made a new attempt.
Using a gps disabled configurazion i managed to arm the motors.
I added the gps and didn't find any combination of settings to make config botton greeen.
Then i stopped because the gcs stopped to move and there was no way to make it work again even disabling anywhere the gps.
I stop to try.

I tied to apply the coorrections you suggested but config botton remained red and gcs did not respond to the quadcopter movement any more.
I made many attempts to restore it aslo loading old functional .uav without gps but gcs was not restored.
I made an upgrade and erase and gcs move but now the op-link id is blank
I made an upgrade and erase of op-link but it is still blank.

How can i restore op-link id to copy it in controller configuration?

- The standard prop / motor direction is counter clockwise when viewed from the front of the motor (as if it were mounted on front on a normal airplane).
- If you want standard props to work in the future you should make the motor direction backwards (make it clockwise when viewed from the front of the motor).

I draw what you said and I forgot to write CW on the model pusher, as the CCW motion from the front was transposed to the CW motion in back. I hope I'm not getting confused...

Different startup times are not a problem.

"One of my motors spins before the other three as I raise the throttle." is your only problem and that is usually ESC calibration / Output Neutral setting.  It could be caused by a conflicting setting, like setting that ESC output to be used to blink a status LED, etc.

do I have to select MAVLink or ComBridge in the hardware config? --
No.

Of course both sides must be configured with the same data rate and some other things must match / be set correctly too (e.g. min/max channel, data+control, coord/receiver) .

There is known bad RF hardware out there.  Put the two devices close together and see if it stops disconnecting, then watch the received signal.  With bad hardware you will see the signal level drop a lot once in a while.  When it is farther away that is when you get disconnects.  If you have 2 bad ones they talk together OK.  If you have 2 good ones they talk together OK.  A bad one and a good one do not work together.

There seems to be a way to tell them apart.  Read this post and then refer back to the first post to see the picture for the large and small X2 on the RFM22B (the RF daughter board on OpLinks and Revos).  Also for a video that shows the RF Level drop.

CW / CCW for motors is always looking at the motor from the spinner nut side.

Your picture shows a CCW full size airplane prop and a CW rotation on the model pusher drawing.

Ah, any other reason I may be getting this issue? Or how could I look at those startup time settings you were on about?

I have tried a few things concerning telemetry: I have tried almost all speeds: 100000, 128000 256000, 57600 and 64000.
All those speeds are very laggy. The first 5 seconds, Rx rate is about 1500B/s then it drops to 100B/s or less.
The only mode that seemed to go a little better is 64000. It was more or less stable at 1500B/s BUT disconnecting and reconnecting every 15 seconds.
I don't know what I am doing wrong. Before updating to NEXT, telemetry was rock solid.
Any suggestions?
Thanks!

Learning new things every day.

Then... I was wrong saying the motor is spinning into the right direction, I'll have to reverse 2 wires.

Yesterday I have watched a video on YT where someone was starting his engine manually.
I have made a screenshot and draw what you explained me, as I have to visualized the things said in your text.

The propeller from the picture from my very first post, is the right one, I will only have to point it front with the small raised propeller size numbers molded into the propeller.
