And here the configs.

Hello,

thank you very much for the settings.

I checked your settings and it is looking good.
I recommend to check this:
1. Enable Servos/Subtrim (Tuning) menu end verify that all servo arms are really in the middle (perpendicular to push rods).
2. At the same time there should be 0° between main blades and swashplate should be level.

Error could be caused also by some kind of mixing in the radio.
We never heard about such issue, so I think that maybe in your radio there is a mix. You can verify it on the bench by disconnecting motor and disarming the throttle hold.

When moving with elevator stick, only elevator channel must move.
When moving with aileron stick, only aileron channel must move.
These two are very important to check.

Hi

I checked the radio twice. I even used a different one to be sure.

How do you set the position for the tail?

On some helicopters the tail can be rotated on the boom. The most of todays helicopters will not allow rotating the tail hub, so I believe this is not the problem on your models.
However it very strange and I can`t find any good explanation. Possibly only unit mounting could cause this if there is everything else OK.
We never experienced such issue unfortunately. Is is even more strange as it happens on both of your models which seems rather something in the radio.

What you can try is to increase Stick Deadband in the Expert Settings to maybe 30 and see if it helps.

Then please make sure that unit is mounted really precisely in all 3 axes with respect to the main rotor.
