Hi jhonny,
Yes, Telega v1 can be used to identify the moment of inertia of the propeller: Propeller dynamics identification - Telega v1.0 Reference Manual
You could switch to Telega v1, run the identification, then switch back. However, we have found that with Telega v0 specifically, the best results are achieved through manual tuning roughly as described here: Telega v0 quick-start guide - Support / Electric drives - Zubax Forum. The approach I’d recommend is first to zero the PID gains and get a rough approximate tracking using the feedforward terms alone. After that, add the PID terms one by one as described. This way achieving good performance is a relatively straightforward task.
