between old and new motherboards of different is TPM
some motherboards they have tpm while the old motherboards they don't have this tpm
it is a required protection required by windows 11.
Maybe it could be the cause of the problem, from what I've read this error it just happens only on windows 10 and on old pc.
The helicopter flies great for me.
It's all set up now.
Can I ask you a question?
in the old version of the software I saved the file on the PC and then also in demo mode I uploaded the file and I studied the parameters to change.
Now in the new version of the spirit software the file is not asked where to save it?

I dont understand the problem with loading backup file. The behavior should be same between old and new version. At least with version 3.6.3.

I replied to you privately.
Listen if I want a helicopter less blocked but more agile I have to increase flight style
or I have to decrease cyclic gain?

with the translation into Italian I can't understand well.

I want a more agile movement when I do flips aileron and elevator
the degrees per second of the servants I'm ok They have the right speed.
the agility of the helicopter I want to increase (just a little)

If you mean Agility as starting reaction of the stick then combination of Cyclic Gain, Flight Style, Cyclic Feed forward will make very big difference.
With increasing Cyclic Feed Forward reaction will change. All 3 parameters are changing behavior of the model, including stick reaction, but in different way.
It depends on what do you want to achieve. Agility is defined differently in each FBL system.
For some FBL unit faster agility mean faster degrees per second - faster roll rate/faster nick rate. This is changed by Rotation Speed for Spirit.
