Good morning,

I’m experiencing some issues with my Spirit GTR system. Specifically, it hangs when attempting to run the governor (ESC YGE Saphir 125 with telemetry connected to the EL2 port). The system starts up without any problems, but after a short period of operation (even when simply powering on and off or moving the servos on the ground without blades), it becomes unresponsive. The motor continues to run at the RPM where it froze, and no commands can be executed. The servos remain in their last position, and the only way to stop the motor is by disconnecting the battery.

I have tested the setup without the governor and with telemetry connected to the EL1 port, and the issue does not occur in that configuration. It seems to be related to the telemetry connected to the EL2 port. I've tested with firmware version 3.7.1, and I plan to downgrade to 3.6.2 to see if that resolves the issue.

Do you have any insights into what might be causing this?

Please take a look at the manual:
https://manual.spirit-system.com/index. ... _Telemetry

Connecting anything at the E2 pin is strictly prohibited and could cause loss of control. You have to use E1 port for this purpose.

But if I connect telemetry to EL1, RPM sensor is not detected; Should I only connect RPM sensor (middle red wire) to EL2?

Yes, RPM should be connected at the middle pin.

OK thank you.

What are the EL1 and EL2 ports discussed here??

I see SAT1, SAT2 JST-XH (Spektrum satellite style) ports and EXT/RPM/E2 port on the servo rail. I don't see the EL1 and EL2 ports discussed in this thread.

Sorry, there was a typing mistake, I meant E1 and E2
