OMP M4 ESC Telemetry and Spirit W1?
Posted: Sun 29. Jun 2025 8:56:26
I have set the ESC Telemetry to 'OMP M4' with the displayed wire connections and my Spirit W1 unit.
Having set the Poles / 2 to 21, I get reasonable ballpark head-speed rpm at about 1850 to 1950, which checks out with a tachometer.
However, the capacity consumed and current displayed are completely out for some reason!
On two flights I got the following:
(1) Displayed capacity used 63744 mAh, where replaced charge was 476 mAh
(2) Displayed capacity used 42248 mAh, where replaced charge was 462 mAh. In the second flight I recorded current peak at 292.6A (for a 65A esc)!
In the first flight way over 300A was initially displayed?
What am I doing wrong, please?
The head speed is not the highest, but still within quoted specifications!
I will check settings again on the computer, this evening, shortly.
Regards,
Andy
