It looks like the problem previously reported on the Jive Pro is back again, see this thread for the initial report: viewtopic.php?f=20&t=2301

I'm running A Kontronik Kosmik 200 with latest firmware (4.15), latest firmware on the Spirit too and on my Jeti Tx. I'm getting the exact same RPM telemetry issues. RPM is reported very low (around 650RPM reported when the real RPM is around 1800).. and most puzzling, when I increase RPM the telemetry RPM decreases :? .

I have the ESC setup with pole count to default '2' and gearing to 1.00:1. In the Spirit I have the correct settings of '7' for the sensor divider (14 pole motor) and 10.7 for the gearing. I even tried 'cheating' and setting the sensor divider to 3, this gave more realistic reported RPM but still the telemetry values decrease when increase headspeed :cry: .

Could it be that the latest Kosmik firmware has re-introduced the old problem again?

Hello,

do you use Kontronik Telemetry or new TelMe Telemetry?
I recommend to second option which should solve the issue completely.

Does it mean that it started right after updating the ESC? If yes, then downgrading back can solve the issue.

Thanks for the reply. No, I'm not using the 'TelMe' module, I'm just using the default telemetry output straight to the Spirit using the special Kontronik>Spirit telemetry cable. All other telemetry parameters are coming though perfectly.

The ESC new new to me. I updated it before installing in the heli so I'm not sure that earlier firmware did work. This was an assumption based on the reports that Kontronik telemetry was working for others, but I may be wrong.
