eLogger BL Motor Sensor settings?

[JeromeF]

I've finally got round to getting my eLogger out and am setting it up ready for the T-Rex 500 and my weekend of flying.

I have the Brushless Motor RPM Sensor but am unsure what settings to use.

So my question is.... How many poles does the 500L motor have and what would be the gear ratio?

Thanks in advance

[JeromeF]

6 Poles and a ratio of 12.46 sound about right ?

[JeromeF]

Or should my ratio be set to 13.50?

The gear ratio would depend on the pinion you are using. The main gear is 162T, so if you are using a 13T pinion the gear ratio would be 12.46.

Wicked, many thanks.

I am using the 13t so will use these settings and get some logs of the RPM.
