Default RPM logging
Hi,

Can anyone explain why my RPM readings are off the chart at the beginning and end of each flight?

I've got my ET connected inline with my regulator and using a magnetic sensor on the main gear of my T-Rex 600n.

All my sessions are like this.

Ignore them, pulse counters will do this at low rpm or when the rpm is changing rapidly.
