All my Spirit heli's are on governor mode and I have always known the motor KV during setup.

The used Gaui X5 Formula I purchased has an unknown brand motor so no KV known. I set my Spirit Pro @ 3,000 max rpm in the setup and have 2250, 2350, and 2450 HS being reported by telemetry at 76%, 81%, and 86% throttle values after 3 gentle test flights.

Should I worry about knowing the KV? If yes, is there a way to use math and the telemetry data while keeping the heli on the ground with light skids to backward determine the motor KV?

Thank you.
