MOD Upgrading the ignition backup battery in a Carbon Cub E/FX-3 (EarthX ETX104)

[Neal]

I pulled the battery and it’s on the charger and appears to be taking a charge. Fault light is out.

The fault light was not on initially

No voltage available to drive it or the BMS.

Out of curiosity why are you guys shutting off Master before you go to idle cut off? I’m going cut off before master off. What am I missing?

I have the same question. Please enlighten us.

 

[Neal]

Yes, I go AV and MASTER off prior to shutdown.

As to the last flight data it shows the same as FlySto, it appears my time from AV/MASTER off to shutdown was too fast for the G3X to record. Maybe AXIS records faster

Attached is the last flight prior to yesterday. I checked several prior flights, all data log the same, V1 and V2 read until the log stops.

That data log stops with engine still turning at 830 rpm. Log samples at 1 Hz. You must have fast hands to get all the power off that quickly.
