Hi, I request your help.

I have a 600 T-Rex FBL in a AS 350 body running with 6S.

After a while I wish to operate this heli again and I updated the spirit 2 to 3.5.0.

I found several stab modes like scale and koaxial. Two years ago there was only one stab mode.

What is the best for me to come back into heliflying again. I don´t want to crash my beauty heli.

Thnks in advance.

Hello,

stabilisation modes were more or less same for years but you can find all descriptions here:

You do not have to use any of them. You can fly your model so you do not have to learn anything new.
More important is if your base setup is correct. It is possible some adjustments are needed, depending on what your previous version was.
