Spirit System

Problem when Unit does not attached to computer:

I have Spirit on my Trex 600N. I tuned the unit using the setup wizard, everything works Just fine. When I unplug the sys cable from computer and unit, plug again transmitter and unit (only reciever battery), all collective servos perform very poorly. Any idea why?
Tnx

It seems like - although I'm not sure - that the software changing to the correct bank (0). Is there a way I can change bank using my transmitter?

Hello,

you can check if banks are changing properly in the Diagnostic tab.
Just flip the switch to see how it is changing and what bank correspond to the position.

Check Bank Comparison in the Backup tab to see difference in your settings between banks.
I am not sure what "poorly" looks like, so it is very hard to answer.
But if they are just moving in a smaller range the problem is just that the values are different between banks. For example Collective Pitch Range could be different.
