So I have Gtr , tribunus iii and Jeti transmitter . The telemetry is set up divider is 5 gear ratio 10.1. Rpm will show on Jeti counts up to about 1260 rpm and as the rpm’s continue to rise towards maximum the display starts over at 0 the gets to about 400 once maximun rpm on heli is reached.. I assume it should continue past 1260 and all the way up to abou 1700 please help see attached vide to understand

I have exactly the same issue on a Spirit GT, Tribunus III 14-150A (HV) and Spektrum RX, divider set at 5 and gear ratio 10.1. The RPM starts back at zero around 1200rpm. Happens on all 4.x fw versions.

I also have another Spirit GT that has been in use for some time but with a Tribunus III 06-110A (LV), Spektrum RX, divider set at 5 and gear ratio 5.53 and have never had an issue, RPM has always been correct.

I am also having the same issue on a Spirit GT, Tribunis II 14-200A, Frsky X18RS, TD-MX, Nexus FBL. Divider set at 5 and gear ratio 10.6
Happens on all 4.x fw versions. Before When I set my gt up the 1st time on 4.0.0 I had it working. When I went to 4.0.1 and 4.0.2 doesn't work. I did go back to 4.0.0 again and now its not working. All other telemetry seems correct.

Hello,

please update to 4.0.2-r2 then it should work properly. It was issue in the latest two firmwares related to Scorpion telemetry. We are sorry for this problem. Fortunately we found it.

Hi, I've just updated the f/w to 4.0.2-r2 and telemetry is all working correctly again :-)

Thanks for the prompt response and resolution.

Just updated to 4.0.2 r2 and on my tribunus II+ 200a, rpm telemetry data is working. Thank you for fixing this. Flying a frsky x18rs and Td-mx.
