I upgraded an RS from 3.3.0 to the latest version.
After update, the ESC is not functioning properly. Motor starts but only slowly and then dies.
The rest of the controls seem to be working..

I checked configuration but did't find any problem.

Is it possible to downgrade back to 3.3.0 to verify that is not the problem.
Current settings app lets me revert a couple of versions but not back to 3.3.0

Any ideas?

Hello,

very likely you only have Spirit Governor enabled. It is enough to turn it off. Possibly it is or was enabled only in some Bank.
This should be not related to firmware upgrade, however there are few parameters you should check after the update.
