Spirit System

I've still not test flown my new TRex 700 Nitro due to issues reading RPM's and therefore uneven engine speeds.

If I flash the new firmware before I test fly again what do I need to reconfigure?
Anything?

You do not need to do any reconfiguration if you are not using Governor from the unit.

If so, then you will need to re-configure Max. parameter, Spoolup rate, Governor Response and Holding performance and to enable Governor in the Bank you wish (mostly all banks).

Yes I will be using the Nitro governor.
